Application No: 2001/168 Accepted: 9 Aug 2001.
Applicant: New Farm Crops Ltd, Lincolnshire, UK.
Agent: Heritage Seeds Pty Ltd, Mulgrave, VIC.
Characteristics (Table 19, Figure 53) Plant: growth habit
erect, height short to medium (mean 84.23cm), frequency
of plants with recurved flag leaves absent or very low.
Lowest leaves: hairiness of leaf sheaths absent. Flag leaf:
anthocyanin colouration of auricles present, intensity of
anthocyanin colouration of auricles medium. Flag leaf:
glaucosity of sheath medium to strong. Time of ear
emergence: medium. Awns: anthocyanin colouration of tips
present, intensity of anthocyanin colouration of tips
medium, length short (mean 100.69mm). Ear: glaucosity
absent or very weak, attitude semi-erect, number of rows
two, shape parallel, density medium, length long (99.5mm).
Rachis: length of first segment short, curvature of first
segment weak. Sterile spikelet: attitude parallel to weakly
divergent. Median spikelet: length of glume and its awn
relative to grain equal. Grain: rachilla hair type long, husk
present, anthocyanin colouration of nerves of lemma
medium, spiculation of inner lateral nerves of dorsal side of
lemma absent, hairiness of ventral furrow absent,
disposition of lodicules clasping. Seasonal type: spring.
Origin and Breeding Controlled pollination: seed parent
‘Chalice’ x pollen parent NFC breeding line. Initial cross
was made in January 1994 in the UK. F 1 plants were grown
in the field between Mar and Aug 1994. 2000 F 2 plants
from this population were sown in New Zealand in Oct
1995 and harvested in February 1996. 300 single ears were
selected from the population in NZ and returned to the UK.
300 F 3 progenies were sown in rows in the field in the UK
and grown from March 1996 to August 1996. 35 F 3 lines
were selected and single F 4 plants harvested from the
selected rows. Selections from this population were based
on early maturity, disease resistance and large grain size. 35
F 4 lines (6921-01 to 6921-35) were shipped to NZ and
grown in 2 metre long rows from October 1996 to February

1997. Disease resistance was used to select two lines that
were sent to Australia for evaluation. The two lines were
planted during 1998 as single plots. During this period the
lines were assessed for general agronomic performance
including type, maturity, height and straw strength. The
plots were harvested for yield and grain recovery. Samples
were submitted for malting quality evaluation. 6921-23 was
selected as the most promising line on the basis of good
agronomic performance and malting quality. 6921-23 was
selected for inclusion in replicated trials during 1999.
During 2000 the line was included in a number of replicated
trials across the barley growing regions of southern NSW
and Victoria. Pure seed was introduced from the breeder
during 2000 and harvested as the beginning of the seed
production process. A greater number of wider ranging
replicated trials were conducted during 2001 to continue to
assess the agronomic performance and malting quality. The
line was submitted for PBR and the field DUS trial was
conducted. Pure seed multiplication continued during the
same season. Selection criteria: high yield, disease
resistance, high malting quality. Propagation: seed.

Choice of Comparators Grouping characteristics used in
identifying the most similar varieties of common
knowledge were – Plant: growth habit erect, height short,
maturity medium; Ear: attitude semi erect. On the basis of
these grouping characteristics following comparator
varieties were included in the trial: ‘Gairdner’ A , ‘Osprey’ A
syn Galaxy A , ‘CK85’, ‘Sloop’ A , and ‘Schooner’. The seed
parent ‘Chalice’ was not included as it has a different
growth habit (intermediate), leaf type (long and recurved),
awn length (long) and ear length (long). The pollen parent
was not included as it is of later maturity than the candidate
variety.
Comparative Trial Location: sown on “Shrublands”,
Heritage Seeds’ Research facility, Riverina Highway,
Howlong, NSW, (Latitude 35º60′ South, elevation 150m),
autumn-summer 2001. Conditions: trial sown into a redbrown
soil with good moisture levels at 55 kg/ha sowing
rate with 100 kg/ha of DAP. Trial design: randomised plots
1.2m x 5m in 3 replicates. Measurements: five plants
randomly selected per replicate from a total of
approximately 1,100 plants.
Prior Applications and Sales Nil.
