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.

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, …

New Yellow Serradella Varieties For Low Rainfall Pastures, Clinton Revell

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

Large areas of acidic, sandy soils in Western Australia's low and medium rainfall, wheatsheep areas are suited to the pasture legume, yellow serradella.

In the past, a lack of varieties with suitable maturity has limited the use of this species.

New varieties developed in Western Australia and significantly earlier in maturity than traditional types can now extend the use of yellow serradella into these regions.

Pasture Improvement In South Western Australia, J W. Malcolm

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

"There is no doubt that Australia's enhanced prosperity in the last 30 years has been dependent in no small measure on the use of legume-based pastures." E. M. Hutron, June, 1968. *

THE LAST 30 years have seen an increased interest in pasture improvement which has transformed much of Western Australia. Large areas have been sown to new and improved pasture species—as a result productivity of both livestock and cereal enterprises has risen.

Wren Wheat Unimpressive In West Australian Trials, Department Of Agriculture, Western Australia

Growing And Marketing Yates For Profit, Frank Melville

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

THE YATES APPLE is a late maturing red variety which because of its good storage qualities enjoyed a prominent place on the late market for many years.

The trees grow and crop well, the only disabilities are insufficient colour under some circumstances, small size fruit and a tendency to shrivel.

All these troubles can be successfully overcome by appropriate management.

Bussell Barley, J L. Mcmullan, J. A. Parish, H. M. Fisher

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

BUSSELL is a new high yielding 2-row barley variety named early in 1967.

An early maturing variety, with white grains of good quality, Bussell has short and extremely strong straw.

It has yielded more than any other variety under test in areas of Western Australia which receive more than 18 inches of annual rainfall.

It has yielded more than Prior in all areas.

The History And Characteristics Of Troodos And Olympus Rose Clover, E T. Bailey, N. B. Gayfer

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

ROSE CLOVER is being produced and used in increasing quantities in south-western Australia. The first line named was designated Kondinin and five lines have now been given cultivar (variety) names.

One of the first samples of rose clover, C.P.I. 13949, introduced into Western Australia proved to be a mixture of two very similar types, differing visibly only in leaf markings.

The mixed sample was named Troodos,* and the selection from it, Olympus.

This paper describes the origin of the two varieties, their history and characteristics.

Varieties And Time Of Sowing, H M. Fisher

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

THE extent to which seasonal conditions favour the various stages of plant development has a marked effect on cereal yields. Because varieties differ in their development they react in different ways to a particular seasonal pattern.

The Naturalised And Cultivated Annual Medics Of Western Australia, B J. Quinlivan

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

Research Report : Chemical Thinning Of Apples, J E L Cripps, N. J. Halse

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

MANY progressive fruit growers have adopted spray thinning of apples, and have found that it pays well.

More widespread adoption to reduce costs of production in the face of returns which show no tendency to rise, would benefit the apple industry.

For this reason improved recommendations have been formulated, based on local research.

Spray Thinning Of Japanese Plums, J E L Cripps

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

THE hand thinning of Japanese plums is the most tedious work which the orchardist is called upon to undertake so that any method of crop reduction other than by hand should be welcome.

Growers may, therefore, be pleased to know that in experiments conducted by the Department of Agriculture several varieties have been successfully spray thinned. The material used was D.N.B.P. (Dinitro secondary butyl phenol).

Spraying with this material considerably reduces but does not eliminate hand thinning.
