Canola : assessment of early maturing Stage 2 lines.

Location: Katanning, Newdegate Research Station, East Beverley Annex

Production of Canola in medium rainfall zones offers the opportunity for a rapid expansion of the industry. However presently recommended varieties take too long to mature for the area's shorter growing season. The Stage 2 trials assess Canola lines selected on the basis of earliness from the remnants of Dr Roy's now defunct rapeseed breeding programme as well as selections from Eastern States breeding programmes. The trials arc conducted at three sites to account for environmental effects on cultivar …

Trial 87A19, 87MT50

Persistence of AMV in annual medic swards.

In 1990, the fourth year of this trial, although the medic plants were numerous the burr medic swards at Avondale grew poorly and weeds were widespread in the plots, especially long storkbill, flatweed and grasses. Poor growth was due to nodulation failure caused by low soil pH (5.3 in water). Hardly any medic plants were left in the Zodiac medic plot at Avondale while a few remained at Mt. Barker.

Location: Avondale and Mt. Barker.

Trial 88A21

Effect of AMV on the productivity of burr medic swards after cropping, regeneration …

Trials: 90GE113, 90MO62, 90WH87, 90ME72, 90NO115, 90A24, 90AB17, 90AL35

Locations: Geraldton, New Norcia, Wongan Hills, Merredin, Southern Brook, Avondale, Katanning, Tenderden.

The selection SEP29.1 was outstanding for both dry matter production and seed yield over a wide range of sites varying in both rainfall and soil type. On the basis of these trials, six lines have been selected for further evaluation in 1991.

They are: SEP29.1 SEP26.2.7 GRC69 GRC87.1 87F01.28 87FB2.36
