New Approaches To Clover Breeding, M. T. Abberton, T. A. Williams, T. P. T. Michaelson-Yeates, A. H. Marshall, C. Jones, E. Sizer-Coverdale, R. P. Collins

IGC Proceedings (1997-2023)

White clover (Trifolium repens L.) and red clover (T. pratense) are the major forage legumes of temperate pastures. Breeding efforts have focused on overcoming the constraints to productivity and reliability in this species and thereby optimising their contribution to mixed swards. In recent years there has been an increased emphasis on livestock production and the efficient utilisation of forage material in the rumen. In this paper we report on a shift in the aims of forage legume breeding at IGER, building on a strong agronomic platform but giving greater consideration to the environmental footprint of our varieties …

Promising Pasture Plants From Overseas, John Lawson

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

Farmers from Northampton to Albany were among the 00 visitors to a spring field day at Agriculture Western Austrslis's Medina Research Station, where they saw a collection of promising new and different pasture legumes. These were the products of a highly succesful selection and breeding program based mainly on material collected overseas.

John Lawson highlights the overseas collection aspects of an exciting and rewarding program.

Developing Improved Varieties Of Subterranean Clover, Phil Nichols, Bill Collins, Dennis Gillespie, Martin Barbetti

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

Subterranean clover is widely recognised as the most important pasture legume species in southern Australia, having been sown over about 20 million hectares.

Together with superphosphate and trace elements, it has been a key factor in improving and maintaining soil fertility, and has resulted in dramatic increases in crop, livestock and wool production.

While the value of subterranean clover is well established, it does have some shortcomings.

Many varieties grown today are not sufficiently adapted to the environments and management systems in use. Others lack sufficient pest and disease resistance.

Improved subterranean clovers are being bred with better adaptation and …

Breeding Field Peas In Western Australia, T N. Khan

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

Field peas have grown dramatically in popularity in western Australia in the past five years, with the planted area increasing from a mere few hundred hectares to about 70,000 ha in 1988. This growth may continue, as more than 700,000 ha of agricultural land is potentially suitable for growing field peas.

However, any such growth of the pea industry will require new cultivars with improved yield, adaptation and quality characteristics to meet local and export demands. The Department of agriculture therefore decided to start a selection and breeding programme to support the pea industry.

Breeding Field Peas : Screening Pea Lines, G H. Walton

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

The early use of field peas in Western Australia was as a green manure crop or to feed stock be grazing the mature crop. Varieties which produced a large bulk of green material were sown. There was no control over insects or diseases.

In 1985, the Feseral Government recognised that to realize the potential of grain legumes grown throughout Australia, more research was needed.

One of the Grain Legume Research Council's (GLRC) priorities is species evaluation and variety improvement.

Since 1983, the Western Australian Department of Agriculture has screened advanced crossbred lines from the South Australian breeding programme for its …

Lupin Breeding In Western Australia : The Narrow-Leaf Lupin (Lupinus Angustifolius), John Sylvester Gladstones

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

Over the past seven years the narrow-leafed lupin (Lupinus angustifolius) has become a significant crop plant in Western Australia.

The present crop varieties are the result of a long-term breeding programme started in 1954 with the aim of producing a broad-acre crop from a plant well adapted to our light soils but with a number of characteristics which precluded its use for cropping.

To an original sweet narrowleafed lupin, soft-seededness, nonshattering pods, early flowering and a distinctive appearance to distinguish it from bitter types were progressively added.

The author of this article, Dr. J. S. Gladstones, began lupin breeding at …
