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 90PE11
Location: South Perth.
A survey was conducted to determine the extent of Bean Yellow Mosaic Virus (BYMV) infection in subterranean clover pastures. The pastures were sampled in October by officers from each of the country districts and from south Perth. 100 samples were collected from each pasture, 1 sample every 5 paces , and sent to south Perth. The ELISA test and the Gibbs and Gower formula were used to determine a percentage BYMV infection for each infected pasture.

Losses Causes By And Control Of Important Seed-Borne Virus Diseases Affecting Productivity Of Annual Pasture Legumes., R. Wroth
Experimental Summaries - Plant Research
Trial90V1 and 90W1
Assessment of pasture productivity in subterranean clover pastures infected with SCMV.
Location: Woogenellup, Vasse and Wokalup.
These trials measure SCMV disease progress, herbage and seed production losses in Woogenellup pasture swards which are: (i) initially artificially infected by using infected transplants in the first year; and ii) naturally infected via seed transmission of the virus in year two. Trials are grazed by sheep throughout the season, maintaining the pasture height at less than 20 cm.

Cucumber Mosaic virus in lupins.
A testing service for lupin growers was provided by the Seed Testing Station. The level of CMV in seed was determined in a 1000 seed sample using the ELISA (Enzyme Linked Immunosorbent Assay) technique developed by Dr. R.C. Jones.To speed up processing of samples levels greater than 1.2% were not determined - to do so would have required repeating the test at a different level of grouping. Growers were charged $114 per sample tested. The service was advertised as being available for samples received up until 28 February.

Effects of different levels of infection in seed sown. - 90BA12, 90WH17
Location: Badgingarra and Wongan Hills.
Trials were done at Badgingarra and Wongan Hills in which plots were sown with seed of cv. Gungurru which transmitted CMV at rates of 5%, 1% and 0%. The plots were separated by 30 in wide cereal buffers.

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.

National Subterranean Clover Improvement Programme., P. G. H. Nichols
Experimental Summaries - Plant Research
The National Subterranean Clover Improvement Programme (NSCIP) aims to develop, by breeding and selection, better adapted and more productive low—oestrogen cultivars of subterranean clover for a range of environments in southern Australia. The programme is a collaborative one with the University of Western Australia and consists of two phases: (i) early generation selection, which involves selecting varieties satisfying primary selection criteria; and (ii) field evaluation of advanced lines, which is conducted by the Departments of Agriculture in each State and co—ordinated by the Plant Breeder.
The first phase is conducted at the University Field Station (UFS) and is continued until …
