Annual Report

Michael Kesinger, Chief 

Bureau of Citrus Budwood Registration 

The 2007-2008 fiscal year will be remembered for the new beginnings in Florida’s Bureau of Citrus 

Budwood Registration. The establishment of new foundation budwood sources for Florida’s citrus 

industry has happened before, but never under as dire circumstances as have led to the opening of 

the new foundation greenhouse facility at Chiefland in 2007. The first Florida foundation grove was 

planted north of Haines City in 1959, and was replaced with a second foundation planting located at 

Dundee in 1973, along with a subsequent planting of a foundation grove in 1989 at Immokalee. 

Foundation trees have been kept at several secondary sites, such as Winter Haven, Ona and south of 

Leesburg, over the years. All foundation trees are now located north of the citrus industry in new 

secure greenhouses isolated from citrus pathogens, their vectors and citrus host threats present 

within the traditional boundaries of our commercial citrus industry. Removing and protecting 

foundation budwood source trees outside of the industry became our first line of defense in having a 

healthy nursery industry in Florida. Budwood is the beginning of the nursery tree. It is 

undisputable that the only option growers have is to obtain nursery trees that are not infected with 

citrus greening, or any other graft-transmissible pathogens of citrus, for our industry to survive in an 

era when so many diseases threaten our economic existence. 

The greenhouses were completed at the new Chiefland facility in late August 2007, with the office/headhouse 

construction scheduled for completion later in 2008. The greenhouses comprise a total of 82,000 sq ft. with 4 

separated sections. The facility design requires anyone entering the greenhouses to pass through the office into a 

screenroom where everyone is decontaminated prior to entering a double entry area with an air-curtain which leads to 

a central vestibule, with four separate access doors that lead into separated greenhouse ranges. The greenhouses are 

cooled with fan and pad evaporative cooling systems and all exposed areas are covered with an insect exclusion 

screen. Liquid propane-fired heaters and irrigation provide winter cold protection. 

All trees are planted in the ground to maximize budwood production. The greenhouse ranges have the capacity to 

hold 1,180 trees. Four hundred of these spaces are dedicated to single clonal selections that function to preserve the 

germplasm and to parent subsequent propagations. The remaining 780 tree spaces are designated for budwood 

multiplication for the major commercial citrus varieties. Budwood is distributed from all available trees to registered 

citrus nurserymen, who in turn, are able to start their own scion trees or increase blocks to keep their nurseries as self 

sufficient as possible. The recommended budwood scheme for nurseries is for each individual nursery to set up a 

small number of registered scion trees in a protected greenhouse. The nursery’s scion trees become the basis of all 

future propagation, as these scion trees provide budwood for increase blocks that are used to provide the majority of 

budwood used in nursery propagation. The scion trees are tested for various graft-transmissible pathogens of citrus, 

including annual tests for citrus greening and citrus tristeza virus. Increase blocks are valid for a period of three 

years from budding. All budwood sources are required to be housed in secure enclosed greenhouses with monthly 

inspections in addition to the pathogen testing. 

Eight hundred fifty-one trees representing 311 different clonal selections have been planted in the Chiefland 

greenhouses, and the first limited quantities of budwood were distributed to commercial nurserymen on 1/10/2008. 

Over 41,000 total budeyes were cut for nurserymen during this first year of operation. In early January, the 

temperatures at Chiefland dropped to the low 20’s Fahrenheit; but temperatures in the 50’s were maintained in the 

greenhouses by running 50 percent of the heaters. 


A second foundation facility is planned in Alachua County at an IFAS research center north of Gainesville. This new 

facility will also house the Citrus Germplasm Introduction Program (CGIP) that is now operated out of the Division’s 

Gainesville office. The budwood foundation backup at Boston Farm is planned to hold one accession of every 

Chiefland selection. 

Although no greening disease was found in the Immokalee Foundation Greenhouses, budwood cutting was 

indefinitely suspended from the facility due to the proximity of citrus greening in the adjacent grove. One hundred 

twenty-one of the greenhouse protected budwood trees were topworked to rootstock varieties in order to provide the 

industry a clean source of seed material. Ten different rootstock selections are now in one of the houses. During the 

8 years of greenhouse budwood production in Immokalee, 577,467 budeyes were distributed from the greenhouses. 

Prior to establishing the greenhouses at Immokalee, 1,113,462 budeyes were distributed from the original field 

foundation planting. 

Division of Plant Industry inspectors witnessed the planting of 484 new scion trees this fiscal year. Eighty-two 

percent of the nursery scion trees are less than two years old. Ninety-one percent of the industry’s scion trees have 

been established in greenhouses within the past 4 years. Because of the young age of most scion trees, the average 

budwood yield has decreased from 2,858 budeyes per tree five years ago to 403 eyes this year. 

The pathogen testing of citrus stock will continue in Winter Haven, where proximity to the clean foundation stock 

will no longer be a concern. As nursery production increases, so does the demand for propagating material, and the 

number of source trees increases to meet that demand. Five thousand ninety-three scion trees were registered this 

year, which was a 16 percent increase. The greater number of trees requires a greater number of pathogen tests; 

therefore, the bureau’s laboratory had to become more efficient to keep up with the testing demands. The Budwood 

Bureau implemented real-time PCR testing for citrus greening in October 2007 for foundation and scion source trees. 

Real-time PCR testing is more sensitive and cost effective than the previous tests. Real-time PCR gives the added 

benefit of being able to do multiple pathogen tests from one collection and one extraction. The bureau’s laboratory 

and biological testing program was able to make 33,623 pathogen determinations this fiscal year. 

Grower trends that may impact the nursery industry, such as open hydroponic systems that may result in earlier fruit 

production and a higher demand for nursery trees as higher tree planting density are envisioned. Mechanical 

harvesting may also change the way nursery trees are grown as higher –headed trees may require additional time in 

the nursery before planting. Nurseries have already expanded greenhouse capacities, and propagations reached 3.5 

million this year (the highest production level in four years). The number of citrus nurseries has also increased, as 

several nurseries resumed production in new greenhouses at their previous locations. Several other nurseries were 

able to locate on new sites away from commercial citrus. Forty-two commercial citrus nurseries reported making 

propagations in 13 counties. All citrus nursery stock produced during this fiscal year has been required to be 

propagated in approved greenhouse structures. This is the first full reporting year under the new regulations for 

producing certified citrus nursery stock. 

Hamlin and Valencia continue to be the most widely propagated varieties. Midsweet orange was the third most 

popular variety propagated, followed by Ruby Red and Flame Grapefruits. Swingle Citrumelo has now been the 

number one rootstock for the past 20 years. Kuharske and Carrizo citrange were the 2 nd and 3 rd most popular 

rootstocks utilized. 

This year’s report continues the pattern of recent years in providing more information on nursery propagation. 

Especially significant this year, the recording of nursery propagations to include the break down of use by clonal 

selection, by rootstock, and the reporting of the number of scion and foundation source trees that are available for 

each selection, all in one chart. Also notable: the graphic illustrations of the basic budwood program workings on 

pages 12, 13 and 15.

used. 

DPI Division of 

Plant Industry 

Data for propagation figures are taken from 

submitted nursery plats. In the early years, a 

smaller portion of the budwood cut was 

platted as the program was voluntary. Only 

those propagations that were properly 

platted were designated as registered. 

Numbers taken from Bud Cutting Reports 

would be much higher. Starting in 1995-96 

the amt cut was used, Since 1995-96, the 

amount budded figure is used when numbers 

are divided by various rootstocks.

Historical look at the numbers of tests run for routine citrus pathogen indexing. A larger number of indicator plants were used as the number of indicators 

per test varied from 3 to 10. 

1 Due to citrus canker concerns and the proximity of clean stock to testing areas, testing of outside sources of budwood was suspended. This reflects in 

lower numbers of tests performed 2004-2007. Testing will resume once clean stock is moved out of Winter Haven.

Pathogen Testing 

Viroid Testing 

Testing for viroids has always been anchored by the biological test in Etrog citron which is very 

effective in picking up a wide range of isolates of Citrus viroids I, III, IV, V and citrus exocortis viroid 

(CEV). PCR is used as a quicker and more specific test, and it can detect all the above viroids and in 

addition, viroid II (which includes cachexia). All of these viroids are endemic to Florida. 

The decline in the number of biological testing starting in 2004 was because of the perceived risk of 

bringing in canker from sampled trees. The continuing smaller numbers has related to increasing 

workload with no increase in personnel, and the increased sensitivity, efficiency and cost savings of the 

PCR tests. 

This year a majority of the scion grove trees were tested for citrus viroids II, III and citrus exocortis 

viroid. Many of the remaining viroid tests performed this year were on the pathogen collection for 

perfecting each test and to make each test as economical as possible. 

Psorosis Testing 

Psorosis biological indexing at cool temperatures in Madam vinous sweet orange detects other 

pathogens in addition to psorosis. It is essential for new parents entering the program. It is our longest 

test as the greenhouse available for this test can only produce the required low temperatures from 

approximately December through April. As psorosis can be vectored from tree to tree through the soil 

in other countries, it is very important that we re-test for this pathogen. The availability of antisera for 

psorosis was the reason for starting ELISA testing in 2001. The earliest antisera was very sensitive, but 

later this was not available, the results not as promising and it was discontinued in favor of PCR testing 

which was tricky and performed only on a small scale to speed Shoot-tip grafts. The PCR test 

continues to be improved and some day re-testing starting with foundation trees may be possible. 

Citrus Greening 

Citrus greening testing is done annually as a check that no vectors were able to get inside of approved 

structures and spread citrus greening. The annual collection of samples is based on the time of year 

that is best for detection of citrus greening as this is such an important pathogen with great implications 

if it enters the citrus budwood stream. Testing began with the Budwood Bureau Laboratory doing all 

of the extractions and Southern Gardens Diagnostic Laboratory running the PCR. This year we also 

assumed the PCR testing; our laboratory did 6,811 extractions and 6,069 citrus greening PCR tests. 

Citrus Tristeza Virus 

Testing for citrus tristeza virus (CTV) in Florida is unique as we allow mild strains of tristeza to be 

present in Foundation trees. The test in use since 1997 has been ELISA. This test allows the 

discrimination of most of the decline and stem-pitting strains of tristeza from the mild strains. Most of 

the heavily used commercial clones are available without CTV and we are in the process of cleaning 

the remaining cultivars. 

When CTV testing was assumed by the state, it meant another collection of samples as ELISA 

required a different type of extraction process. We are in the process of converting to the more 

sensitive PCR test for CTV. This more sensitive test can be run from the same sample used for citrus 

greening testing, cutting in half the number of collections from scion groves. 


Florida Parent Tree Introduction and Shoot-Tip Grafting 

Parent tree indexing consists of comprehensive testing of trees with germplasm new to the Budwood Program. 

Biological testing is used for Citrus viroids and Citrus psorosis virus and PCR for the remaining endemic 

pathogens. With the presence of Citrus Greening, shoot-tip grafting is a very important tool, for the safe reintroduction 

of field material into the Citrus budwood stream in conjunction with complete testing. Of the 71 

trees currently in the Parent Tree Indexing Program, 18 were entered this year. 

In 2007-2008, 753 shoot-tip grafts were set up, of these, 74 were grafted into rootstocks in the greenhouse. 

Unless there are multiple diseases, or particularly difficult diseases to remove, a maximum of three grafted STGs 

of each variety are used for testing. Fifteen shoot-tip grafts (STGs) were released. The following pathogens 

were removed: severe CTV (12 varieties), mild CTV (one), exocortis viroid (one) and blight protein (one). 

At the end of the fiscal year a total of 111 cultivars were in various stages of being shoot-tip grafted. The 

number in each category is a moving target as STGs are moved along as quickly as possible, especially those 

cultivars assigned a high priority. We have assigned the following stages: On List, InSTG, InTest, Fruit Check, 

and Release. Varieties On List have been identified as needing to be cleaned up, but there is some obstacle in 

the way such as needing to find a source, or the propagations made for a source need to grow to an appropriate 

size. InSTG cultivars are being fit into the schedule depending on their priority and rootstock needed for 

STGing. Some may have been attempted multiple times. InTest cultivars have been successful STGed and are 

undergoing testing. Cultivars undergoing Fruit Check may be top-worked or have a propagation placed outside 

to speed the process. The responsibility for this may be transferred to the owner of the variety if they are willing 

to do so and are more familiar with the characteristics of the fruit. Cultivars undergoing Release have received 

all testing results that are negative, fruit check and have been propagated if they will be kept at Chiefland, and 

the paperwork is being completed. 

There were nine varieties On List. Sixty-six are being STGed. They have the following prioritization: First -28; 

second – 20; third and fourth – 18. First priority is usually those for which there is no clean source, or a newly 

developed variety coming from the field. Second priority being cultivars of lesser interest, and third and fourth 

priorities are those for which there is either less demand, or there is already budwood available, but it is being 

cleaned up to remove mild strains of CTV. 

Twenty-three cultivars InTest were being evaluated for presence of disease with PCR and biological indexing. 

One single STG for each cultivar will be selected for further testing, and fruit evaluation. The selection is done 

by an inspector with the lab to select the one that is most horticulturally sound as well as most advanced in being 

tested. Three varieties are complete with the exception of the Fruit Check. Ten varieties were in the process of 

being released. 

In May, one week of training in Spain’s IVIA citrus Center was focused on shoot-tip grafting. Improvements 

from what was learned in Spain are being implemented and improved results are already being seen.

Shoot-tip Grafting (STGing) 

Technique for removing citrus pathogens 

Seedling used for the recipient of micro-graft are grown in test tubes in the dark. 

Bud sticks of the clean-up candidate are sterilized and grown in solid 

media. Heat therapy is applied to remove pathogens. Once the bud 

sticks sprout, they are ready to micro-graft into an etiolated seedling. 

STGing takes advantage of the fact that under optimal 

conditions, apical meristems can outgrow plant viruses 

and viroids. It is used in the budwood laboratory to 

clean-up or remove pathogens from citrus selections. The 

process requires the harvesting of a minute piece of 

meristem and surgically micro-grafting it into sterile 

grown seedlings. The STG is grown in a test tube in 

sterile media under grow lights for optimal growth. 

After the STG has sprouted, it is side-grafted on a 

rootstock in the greenhouse to facilitate growth. 

It could take up to two years before enough tissue is 

produced by the tiny STG plant to be able to retest for the 

target pathogens to verify success. With the use of PCR, 

the first testing can take place within 6 months of 

propagation. The goal is for the STG process from start 

to finish taking 18 months.

Our Vision 

The Bureau of Citrus Budwood Registration’s vision is to provide high yielding, pathogen free, quality 

budlines that will impact the productivity and prosperity of our citrus industry. 

Our Mission 

The Bureau of Citrus Budwood Registration administers a program to assist growers and nurserymen 

in producing citrus nursery trees that are believed to be horticulturally true to varietal type, productive, 

and free from certain recognizable bud-transmissible diseases detrimental to fruit production and tree 

longevity. 

Benefits of a Budwood Program 

The Florida budwood program has greatly impacted Florida citrus, as the use of registered budwood 

selections or “budlines” is responsible for impressive increases in yield and fruit quality in the industry. 

The budwood program introduced many nucellar lines that are still the foundation of many of our main 

varieties. The ability to test for graft-transmitted pathogens and exclude unclean propagating material 

has not only increased production and tree longevity but also the ability of our groves to withstand 

other environmental stresses. 

Diseases are kept out of the propagation system 

o Using clean nursery stock means grower receive disease free trees coming out of the nursery 

Testing for citrus viroids is more critical than ever as the industry uses predominantly 

citrange and citrummelo type rootstocks that are more susceptible to viroids 

o The budwood program is credited with having viroid free trees for the industry to use when the 

rootstocks were changed from rough lemon and sour orange to Carrizo and Swingle 

Other countries without budwood programs had major viroid problems when changing 

rootstocks away from sour orange 

Citrus tristeza virus strains are worse today than a few years ago 

o Stem pitting tristeza virus strains have been found in several commercial grove locations in 


Psorosis virus is becoming hard to find in Florida after 50 years of budwood registration 

o Prior to the budwood program psorosis was widespread in Florida 

Yields in psorosis infected trees were reduced 10 to 35 percent and made the trees easier 

to succumb to cold and other environmental stresses 

Protection of our industry from exotic citrus diseases requires controlling citrus 

propagating material 

o Citrus greening is the latest disease to move from the exotic disease list to become an endemic 

disease. 

o Citrus variegated chlorosis and sudden death diseases are examples of unwanted pathogens 

whose main means of control is budwood certification 

Grove trees started from clean stock have the potential to be profitable even in the 

presence of disease, whereas nursery trees started systemically infected will never 

become profitable grove trees 

Yields are increased with registered budwood clonal selections 

o Nucellar Valencia clones alone increased yields by 25% over old line selections 

o Examples of registered clonal selections in every variety show remarkable yield gains 

True to type varieties and rootstocks are propagated 

o Inspected trees with off-types are removed from budwood supply 

Budwood programs are recognized world wide as the most effective means of excluding 

and containing citrus graft-transmissible pathogens.
