PLANT VARIETIES JOURNAL 2000 VOL <strong>13</strong> NO. 1<br />
anthocyanin colouration absent, sheath glaucosity strong.<br />
Stem: straw pith thin. Ear: glaucosity medium, semi<br />
recurved, tapering, white, lax, fully awned. Lower glume:<br />
shoulder width medium, shoulder shape elevated, internal<br />
hairs strong, glume beak length medium to long, slightly<br />
curved. Lemma: straight. Grain: Prime Hard (PH) grade,<br />
white, ovate to elongated, germ face shallow, width<br />
medium, brush length medium, end profile medium.<br />
Disease Resistance: moderate resistance to stem, leaf and<br />
stripe rust. Resistant and intolerant to Cereal Cyst<br />
Nematode (CCN), susceptible to flag smut and susceptible<br />
to very susceptible to yellow leaf spot.<br />
Origin and Breeding Controlled pollination: seed parent<br />
BD225 (‘Cook’*2/ ‘Millewa’//TM56) x pollen parent<br />
CD87 (‘Pavon’S’/‘Condor’). The seed parent BD225 is<br />
moderately susceptible to leaf rust, ‘Chara’ has moderate<br />
resistance to leaf rust. The pollen parent CD87 is<br />
susceptible to CCN ‘Chara’ is resistant to CCN. The<br />
original cross was made in 1988 at VIDA, Horsham,<br />
Victoria, single plants selected in the F 2 and F 2 derived F 3<br />
lines were evaluated for disease resistance and agronomic<br />
type. Single spike selections were taken in F 4 and again in<br />
F 9 to ensure uniformity for disease resistance and<br />
agronomic characteristics. Selection criteria: Stem, leaf and<br />
stripe rust resistance, resistance to CCN, agronomic<br />
adaptation to southern New South Wales, central and north<br />
eastern Victoria. Propagation: by seed. Breeder: Peter<br />
Martin, Agriculture Victoria Services, Horsham, VIC.<br />
Choice of Comparators ‘Condor’ was chosen as a<br />
comparator because it is a semi dwarf, white chaffed, fully<br />
awned spring wheat of medium to late maturity similar to<br />
the candidate. ‘Condor’ is used extensively in the seed<br />
parent BD225 (Cook*2/Millewa//TM56) via TM56<br />
(Aus10894/4*Condor) and in the pollen parent CD87<br />
(‘Pavon’S’/Condor). ‘Mira’ was chosen as a comparator<br />
because it is also a semi dwarf, spring wheat of similar<br />
mature height to the candidate. ‘Mira’ has a similar pedigree<br />
to ‘Chara’ via its pollen parent XD85<br />
(TM56/Agent//4*Condor). Both comparators are varieties<br />
of common knowledge. ‘Cocamba’ (a sister line of TM56)<br />
was initially considered but later was excluded because it is<br />
susceptible to stem rust and leaf rust.<br />
Comparative Trial Comparators: ‘Condor’, ‘Mira’.<br />
Location: Avon Districts Centre for Cropping Systems,<br />
Northam WA. Sown 9/6/99. Conditions: plants raised in red<br />
loam pH 5.6 in CaCl2 in open beds. The plots were treated<br />
with glyphosate on 30/5/99 and Sprayseed® on 10/6/99,<br />
Hoegrass® at 1.5l/ha on 1/7/99 was applied for grass control.<br />
Brodal® at 150 ml/ha on 7/7/99 was applied for wild radish<br />
control, no treatment for disease or insect control was<br />
required. Agras No 1 at 120 kg/ha was drilled with the seed<br />
and Urea at 80 kg/ha was topdressed at early tillering. Trial<br />
design: plants sown in randomised complete blocks in 10m x<br />
1.42m plots (8 rows) with 2 replications. Measurements:<br />
taken from 10 specimens per replicate selected randomly<br />
from approximately 2000 plants. One sample per plant from<br />
twenty plants at random. One sample per plant.<br />
