Breeding Phomopsis-Resistant Lupins, John Sylvester Gladstones
Journal of the Department of Agriculture, Western Australia, Series 4
The release of Gungurru and Yorrel lupins marks the coming of age of the narrow-leafed lupin as a crop plantt. These are the first cultivars of the species th have substantial resistance to Phomopsis stem blight, which will make the stubbles much safer for grazing stock.
This article describes the new lupins, their background, and how they were bred. It also acknowledges the contributions of colleagues who helped in important ways.

The planting of Phomopsis-resistant lupins will increase net farm income. They will also alter the traditional blend of pastures and cropping, depending on grain and wool prices. In mixed farming areas of Western Australia's southern wheatbelt, they will allow more land to be sown to lupins rather than cereals on farms in which the lack of sheep feed over summer severely restricts wool production.
The benefits of Phompsis-resistant lupins arise from a reduction in sheep deaths due to lupinosis, a longer safe grazing period (free from lupinosis) on lupin stubbles, a decrease in the need for supplementary sheep feed over …

Leaf Diseases Of Wheat And Time Of Sowing, J M. Wilson
Journal of the Department of Agriculture, Western Australia, Series 4
Leaf diseases of wheat can be avoided by delaying the planting of a crop, but this often leads to reduced yield because the benefits of early sowing usually outweigh anylosses caused by leaf disease.
However, it is only in exceptional circumstances that farmers need to consider leaf disease when making decisions about planting date, as this article shows. Most examples are taken from department of Agriculture trials in its northern advisory region, but the principals apply to other agricultural areas.
