Phomopsis-Resistanct Lupins : Breakthrough Towards The Control Of Lupinosis, W A. Cowling, J. G. Allen, P Mcr. Wood, J. Hamblin
Journal of the Department of Agriculture, Western Australia, Series 4
Attemots to control lupinosis in sheep have been thwarted by the unpredictable occurence of the disease in the field. The complex interaction of the toxin-producing fungus (Phomopsis leptostromiformis) with its host (the lupin plant), together with variable weather and paddock grazing conditions, have made it difficult to predict when stock are in danger of contracting the disease. The risk of lupinosis discourages many farmers from growing lupins, despite the many potential benefits of including them in crop rotations.
A team of Department of Agriculture plant breeders, plant pathologists, and animal scientists set out in the mid 1970s to find resistance …

Reduced-Branching Lupins, R J. Delane, J. Hamblin, J. S. Gladstones
Journal of the Department of Agriculture, Western Australia, Series 4
The flowering time of present narrow-leafed lupin varieties is now probably correct for most of Western Australia's grain growing areas. However lupin yields are frequently not as high as might be expected, in either low or high yielding sistuations, and further marked yield improvements seem theoretically possible. A likely reason for seed yields being below expectations is the growth and development pattern of present lupin varieties.
Some new lupin types in which branching is suppressed genetically - known as reduced-branching types - are being studied. These types could be useful in some lupin growing areas to help overcome seed yield …

Preventing Lupinosis With Phomopsis-Resistant Lupins, Jeremy G. Allen, W. A. Cowling
Journal of the Department of Agriculture, Western Australia, Series 4
Lupinosis is one of the major livestock siseases in Western Australia. It is caused by stock eating toxins produced by the fungus Phomopsis leptostromiformis which colonises the stems of dead lupin plants.
In 975, the Department of Agriculture started a breeding programme to develop Phompsis-resistant lupins to overcome or control lupinosis. In the previous issue of this Journal the results of small plot evaluations of new lines of Phompsis-resistant lupins developed in this programme were reported. This article describes the first trial involving grazing of Phompsis-resistant lupins.
