Managing Lupin Anthracnose, Greg Shea, W A. Cowling, B J. Burchell, D Luckett, H Yang, Mark W. Sweetingham, Geoff J. Thomas

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

Anthracnose in lupins was first reported in commercial crops in Western Australia in September 1996. By October 1996, several thousand lupin breeding lines and wild types of 11 lupin species were sown in New Zealand for resistance screening. In 1997, resistance to anthracnose was confirmed in several breeding fines and commercial cultivars of narrow-leafed lupins (I. angustifolius), landraces of albus lupins (I. albus) and wild types of several other lupin species. Important information on critical seed infection levels and fungicide seed treatment has also been determined.

Pulses : Profitable New Crops For The Wheatbelt, Kadambot Siddique, Stephen Loss, Ian Pritchard

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

Narrow-leafed lupins have beeb produced on sandy acid soils throughout the wheatbelt for more than two decades. However, the wheatbelt contains large areas ofsoilsnot suited to narrow-leafed lupins. For several years reasearchers have been examining alternatives to narrow-leafed lupins for these soils.

Kadambot Siddique, Stephen Loss and Ian Prichard look at production of these new grain legumes, known as pulses.

Cucumber Mosiac Virus In Lupins, Annette Bwye, Roger Jones, Wayne Proudlove

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

Cucumber mosaic virus is a threat to lupin crops from Geraldton to Esperance, particularly to those growing in areas receiving more than 400 mm average annual rainfall. The disease markedly decreases grain yield in narrow-leafed and yellow lupins but doesnot infect albus or sandplain lupins. Worldwide , after bean yellow mosaic virus, cucumber mosaic virus is the second most important virus affecting lupins. Annette Bwye, Roger Jones and Wayne Proudlove outline the symptoms, spread and management of this serious disease.

Fast Tracking Barley Varieties Using Anther Culture, Sue Broughton, Penny Priest

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

Breeding new varieties of barley or other cereal crops usually takes between 12 and 15 years. five years of that time may be needed to stabalise the new varieties so that they breed trueto type, but anther culture can reduce this delay to only eight months. This technology will allow the Department of Agriculture's barley breeding programme to respond more rapidly to changes in goals set by industry and to meet market demands.

Crops In The Woolbelt : Current Options And Emerging Prospects, Wal Anderson, Ross Gilmour, Robyn Mclean, Peter Nelson, K H.M Siddique, Paul Carmody, Ian Prtichard

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

It has traditionally been more profitable to grow sheep for wool in the medium rainfall parts of the south-west of Western Australia than to grow crops . Crop production has been difficult owing to the hilly terrain, the frequency of waterlogging, the high incidence of damaging frosts in some areas, the frequency of losses from diseases, difficulties with wet weather at harvest, and a lack of adapted crop varieties.

Advances over the past decade have made cropping on a limited scale potentially profitable in the woo/belt.

This article is intended to bring the various options for crop production to the …

Production Of High-Value Wheats : One Sustainable Answer To The Cost:Price Squeeze, Wal Anderson, Alan Peggs, Doug Sawkins

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

Farmers and scientists alike over the past decade have sought to address the declining terms of farm trade (the cost.price squeeze) by increasing wheat yields in ways that will ensure both their economic and ecological survival. Nevertheless, costs have continued to increase as a proportion of the value of the product.

Many farmers have increased their wheat yields substantially and the industry as a whole is more conscious of the quality of its product.

Over the past 10 years or more there has been intense interest in, and considerable adoption of. conservation farming techniques such as minimum tillage, residue retention, …

A Tale Of Two Ladies : Pink Lady And Sundowner, John Cripps, Eleanor Melvin-Carter

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

It is five years since the first Western Australianbred Pink Lady and Sundowner apples were sold on the local market. In that time, these crisp, sweet flavoursome apples have become top-selling, premium fruit.

The story is no different overseas. Trial shipments to London, Taiwan and Singapore have indicated a big demand for the unique Pink Lady apple - far more than Western Australia can presently supply.

One million fruiting Pink Lady apple trees are needed to meet anticipated export sales. Today, there are only 100,000 trees in the ground, of which about half are bearing fruit.

New high quality apple …

Domestication Of Rough-Seeded Lupins, Bevan Buirchell, Wallace Cowling

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

Wheat Quality And Wheat Variety Decisions, Mark Stevens

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

The choice between which wheat variety to plant has always been a trade-off between yield and wheat quality. When wheat prices were higher and quality payments were less, quality considerations were of little importance and varieties were selected almost entirely on yield potential. Now, with low wheat prices and a greater emphasis on wheat quality from our customers, growers must place more importance on quality characteristics when selecting varieties. For example, should a grower select a higher yielding average quality wheat such as Spear, or a lower yielding, good quality wheat such as Machete? The important question a wheat grower …

Increasing Wheat Yields Through Breeding, B R. Whan, R. Gilmour

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

With the current 'cost price' sueeze facing Australia's farmers, the development of new higher yielding varieties is moe important that ever. By growing higher yielding varieties, farmers can increase their returns at virtuakky no additional cost: for example a wheat variety that produces 5 per cent extra yield from 1 t/ha crop returns about an additional $8/ha. Farmers can therefore increase their production by growing improved varieties.
