Details of Comparative Trial<br />
Location<br />
Tamworth, NSW<br />
Descriptor<br />
Grass (General descriptor for grasses) PBR GRASS<br />
Period 2006-2009<br />
Conditions Trial field is alluvial flood plain bordering the Peel River 7<br />
km's west of Tamworth. Soil is deep and predominately<br />
silt/clay loam. It has very good moisture-holding traits, very<br />
fertile with no element deficiencies. The only fertilizer used is<br />
nitrogen at high rates which is necessary to stimulate seed<br />
setting, not plant growth<br />
The climate here has a definite winter spring summer fall<br />
cycle. Winters are very frosty which is needed to cause<br />
Kikuyu to go dormant. Dormancy is vital to good seedsetting.<br />
Spring and summer are not too hot, very few days<br />
above 38 c, very hot summers causes kikuyu to stop<br />
flowering. Falls here are usually dry, an absolute must for<br />
harvest as the crop has to be put thru the harvesters up to 5<br />
times. The climate has been true to history and my yields<br />
have been good. The trials were planted 20 Feb. as are all the<br />
seed crops and the mild autumns have given good growth<br />
before the first frosts.<br />
Trial Design Trials of 8 plots at Tamworth were irrigated by overhead<br />
pivot and no fertilizer or pesticides were used. 24D Atrazine<br />
was used 3 times for weed control.<br />
Measurements Measurements were taken per plant randomly from eight plots<br />
were developed for PBR trial and measurements for stolon<br />
lenth of internode were taken from 60 samples.<br />

Origin and Breeding<br />
Selection from source material: Breeding conducted by field selection from 1 acres of<br />
‘Noonan’ – ‘Noonan’ seed supplied by NSW Department of Ag Grafton and planted<br />
very thin by drill on 1 acres. <strong>Plant</strong>s were selected on basis of leaf size, length, colour,<br />
stolen length and node intervals. Colour by selecting only darker plants. All plants<br />
were selected for turf qualities only. Only the least aggressive and densest plants were<br />
selected. Selected plants were transplanted on 1 acre area and managed for seed<br />
production. Seed harvested was replanted on a new 5 acre plot and any off-types were<br />
eliminated by digging up. The plot was then managed for seed production and<br />
harvested seed was sown on 25 acres. Seed was taken to Tamworth and planted on 80<br />
