The project 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 …

Annual Medic Evaluation On Eradu Sandplain Soil - Plots, Bradley Nutt, M. K. Laslett

Trial 88EC17

Location: East Chapman Research Station.

The plots were hand sown at 2 g/m2 of inoculated and lime pelleted seed. The medics were inoculated with WSM540 which may have been ineffective on some of the M. littoralis and M. tornata varieties. The time taken to form ripe pods was monitored to gain some extra measure of maturity besides flowering time for comparing wide ranges of species. The ripening time involved was very similar over all the varieties, averaging out to 44 days after the flower opens. What appears to be a more important factor when considering maturity is the …

Miscellaneous Publication 11/88 - Manjimup Horticultural Research Centre - A Guide To Activites, David Johnston

Horticulture published reports

Within the south-west of Western Australia, in the area encompassed by Bunbury, Margaret River, Albany and Manjimup, the horticultural industries have become of major importance to economic viability and employment opportunities.

The Manjimup Shire grows45 percent of the State's potatoes, 50 per cent profits cauliflowers and 32 per cent profits apples. Other important crops are onions, beans and peas for processing and Chinese cabbage. A range of other horticultural crops are produced on a small scale.

The recent establishment of an Edgell-Birds Eye processing plant at Manjimup will provide a further significant boost to the region. By 1992 this plant …

Location: Avondale, New Norcia, Darkan, Cranbrook, Arthur River, Kellerberrin North Quairdading, Gabalong, Merredin, Badgebup and Pingrup.

Over 300 recent overseas introductions of murex medic were evaluated in rows at South Perth in 1988. Of these 15 selections were identified with acceptable spinniness that flower in 100 days or less. Four years ago there was only one selection flowering in under 110 days and that was spiny!

These selections will be evaluated in small plot trials in several country sites in 1989.

This programme aims to identify superior varieties to Zodiac which was released in 1988.

Tolerance Of New Cereal Varieties To Current Herbicides., D Bowran

Experimental Summaries - Plant Research

Trial 88EB26

While this site had a low population of weeds no yield increases were apparent. Few variety differeces were apparent at this site, though Hoegrass + Glean reduced yield of Crabook significantly.

Trial 88EC27

Few crop effects were experienced at this site. The major effect was due to variable fertility in replicates 3 and 4 and this resulted in the somewhat uyp and down nature for the Glean, Logran and hoegrass results.

Improving Lupin Pod Setting And Yield, R J. Delane

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australia's lupin production has grown twenty-fold since 1977. Lupins are now a valuable seed, feed and rotation crop on light-textured neutral and acid soils throughout southern Australia. Nevertheless, both experimental and commercial yields have been variable over sites and seasons. A major cause has been excessive flower and pod abortion on the main stem. Farmers have often commented on well grown lupin crops which appear to carry few pods

Murex Medic : A New Pasture Species, Dennis J. Gillespie

Journal of the Department of Agriculture, Western Australia, Series 4

Murex medic (Medicago murex) is a new species of medic not previously used commercially anywhere in the world. The first variety, Zodiac, was developed by the Western Australian Department of Agriculture and released to seed producers throughout Australia in 1988. Other varieties are being evaluated and further releases are likely in a few years.

Trial 88EC31

This site received a basal treatment of 1.5 L of simazine/ha prior to seeding. Due to a heavy stubble load lupin seed was dropped onto the surface and lightly incorporated.

High rates of Simazine were better tolerated by Gungurru 75A/260 and CE2/435. The highest rate of Brodal reduced yields in all varieties except Gungurru.

Trial 88EB27

This site was severely infested with aphids and bean mosaic virus such that the varieties Illyarrie and Danja had up to 60% plant death by anthesis. Other varieties were affected but to a lesser extent.

Journal of the Department of Agriculture, Western Australia, Series 4

The release of Santiago follows an extensive Department of Agriculture testing programme conducted primarily in the 325 to 425 mm rainfall zone. Santiago substantially outperformed both Serena and Circle Valley and was the best amongst the large number of non-commercial medic varieties tested. About 500J000 ha were sown to burr medic between 1983 and 1988 and the Department of Agriculture expects that the release of Santiago will result in additional new plantings from

Objective: To measure reproductive output in relation to times of emergence and herbicide application.

Trial No. 88WH10

Growth of doublegee under summer irrigation.

Objectives: A major impediment to achieving biological control of any annual weed in the wheat belt is that the bicontrol agent must have a means of aestivation. Since the only insect to have been introduced to Australia for a the control of doublegee does not aestivate, it was thought that populations could be able to oversummer in irrigated doublegee standards. The aim of this study was to assess the …

Factors Affecting Frost Damage To Wheat In Western Australia, S P. Loss

Division of Plant Research : Technical Report Series

It may at first seem strange that precious research funds are being channelled into a project concerned with frost damage in a country where high temperatures and moisture stress limit the growth of plants for a large portion of the year. But cereal crops are only grown in the temperate zones of the continent during winter and spring when they may be exposed to low diurnal temperatures. In many areas cold damage is irregular and rare,however it limits yields not only by causing actual damage but also by restricting the most effective period for flowering. For muck of the Australian …
