鉴定与筛选来自国内外938份蚕豆种质对赤斑病(Botrytis fabae Sard.)的抗性,结果表明:中抗品种96份,占总数10.23%;中感品种386份,占41.15%;感病品种295份,占31.45%;高感品种161份,占17.16%.中抗品种来自蚕豆赤斑病常年发生严重的浙江、湖南、江苏、湖北等省.品种抗性类型与该病引起产量损失、粒色和粒型大小的关系分析显示,中抗品种在该病流行年份,不施药防治也能保持较稳定的产量,说明能基本控制该病流行为害;中抗品种的籽粒以中粒型为主,仅有极少数材料为大粒型,而且其粒色以绿色为主,乳白色和浅绿色有一定比例.
Identification and screening of 938 domestic and foreign germplasms of broad bean germplasm resistant to red spot (Botrytis fabae Sard.), The results showed that: 96 resistant varieties, accounting for 10.23% of the total; susceptible varieties 386, accounting for 41.15%; 295 cultivars, accounting for 31.45%, 161 cultivars with high susceptibility, accounting for 17.16% .The resistant varieties were from Zhejiang, Hunan, Jiangsu and Hubei Provinces where annual occurrence of annual red spot of Vicia faba was serious.Resistance varieties and the yield The relationship between loss, grain size and grain size showed that the resistant varieties could maintain a stable yield in the epidemic-year without application of pesticides, indicating that they could basically control the disease epidemic. Grain-based, only a very small number of materials for the large grain, and its grain color to green-based, milky white and light green have a certain percentage.
