Period 2010<br />
Conditions<br />
A comparative trial was sown on the Roseworthy Campus of<br />
the University of Adelaide. In 2009 the area carried a faba<br />
bean crop which was harvested for grain and the resultant<br />
stubble was baled and removed. Pre-seeding herbicides Boxer<br />
Gold (2.5L), Roundup Powermax (1.5L) and Lontrel (100ml)<br />
together with an insecticide Imidan (150ml) were applied<br />
prior to seeding on 3 Jun 2010. 90kg DAP fertiliser was<br />
applied with the seed. The season was very favourable for<br />
growth of the crop and of weeds and disease, so the trial was<br />
sprayed post emergence with Hussar OD (100ml), Lontrel<br />
(100ml) to control weeds, with Rogor insecticide (100ml),<br />
fungicide Opus 125 (500ml) for stripe rust and powdery<br />
mildew. Crop performance was enhanced with the application<br />
of micrunutrients and urea (50kg). Late in the season aphids<br />
needed to be controlled and Chlorpirifos (400ml) and Alphacypemetherin<br />
(200ml) was applied. At no time was the trial<br />
stressed by the weather so varieties were able to fully express<br />
their genetic potential.<br />
Trial Design Randomised block design of 3 blocks and 16 entries<br />
consisting of comparators and potential candidates. Sown in<br />
12 ranges of 4 plots wide, block 1 being in ranges 1 to 4 and<br />
so on. Plots were 1.25m wide (5 rows) and 3.2m long. There<br />
were approximately 1000 plants per plot.<br />
Measurements Qualitative characters were recorded for every replicate at the<br />
appropriate growth stage. Quantitative characters were<br />
measured on 10 randomly sampled plants from each replicate,<br />
the samples being taken at the appropriate growth stage or<br />
after maturity. Statistical analyses were completed using<br />
GENSTAT software.<br />

Origin and Breeding<br />
Controlled pollination: A single cross between a University of Adelaide breeders line<br />
(TX93-19-2D-3) and the variety ‘Treat’ was made in 1999. A total of 25 F 2 derived<br />
doubled haploids were produced from this cross in 2000. Seed was multiplied in the<br />
