羽扇豆炭疽病[由Colletotrichum lupini (Bondar) Nirenberg、Feiler 和 Hgedorn 引起]于 1996 年首次出现在西澳大利亚州 (WA) 的经济作物中，严重影响了羽扇豆产业，特别是在西澳大利亚州北部粮食带。随后的研究确定了窄叶羽扇豆（Lupinus angustifolius L.）和白羽扇豆（Lupinus albus L.）对这种疾病的良好抵抗力来源。然而，直到最近，黄羽扇豆（Lupinus uteus L.）还缺乏可靠的抗性来源。对从全球各地获得的材料进行筛选，发现了三种假定的抗性来源。在抗性品系和其他育种品系之间进行杂交。因此，已经开发了几种对该疾病具有部分抵抗力的育种品系。这是关于黄羽扇豆炭疽病抗性发展的第一份报告。这种水平的抗性应该为西澳西南部种植黄羽扇豆提供足够的保护，因为该地区没有炭疽病病原体的永久天然宿主蓝羽扇豆（Lupinus cosentinii Guss.）。
Lupin anthracnose [caused by Colletotrichum lupini (Bondar) Nirenberg, Feiler & Hagedorn] first occurred in commercial crops in Western Australia (WA) in 1996 and severely affected the lupin industry, particularly in the northern grain belt of WA. Subsequent studies led to the identification of good sources of resistance to the disease in narrow-leafed lupin (Lupinus angustifolius L.) and white lupin (Lupinus albus L.). However, a reliable source of resistance was lacking in yellow lupin (Lupinus luteus L.) until recently. Screening of accessions obtained from various parts of the globe yielded three putative sources of resistance. Crosses were made between the resistant lines and other breeding lines. Consequently, several breeding lines have been developed with a partial resistance to the disease. This is the first report on the development of anthracnose resistance in yellow lupin. This level of resistance should provide enough protection to grow yellow lupin in southwest of WA as this region does not have blue lupin (Lupinus cosentinii Guss.), a perpetual natural host of the anthracnose pathogen.
