小麦品种资源抗条锈性鉴定

IDENTIFICATION OF RESISTANCE TO STRIPE RUST IN WHEAT VARIETIES

1986～1990年对甘肃3578份小麦品种资源抗条锈性分小种鉴定结果,冬麦区,陇南的品种抗条锈性明显好于陇东;春麦区,甘肃中部和临夏的品种优于河西。亲本以繁六、钱保德、水源11、抗引655、7084和柯斯的杂种后代抗条锈性强;洛夫林10号、13号、牛朱特和山前等“洛类”品种的杂种后代多数感染条中29号小种,国内各省品种的抗锈性,西部品种的抗性比东部好;国外材料表现免疫至高抗的有Aminda、Ibeech等。

Identification of stripe rust races to 3578 wheat varieties was conducted in Lanzhou during 1986～1990. The results showed that in winter wheat areas resistance to stripe rust of varieties from South Gansu was signficantly stronger than that of varieties from East Gansu; In spring wheat areas resistance to stripe rust of varieties from middle Gansu and Linxia region was stronger than that of virieties from Hexi corridor. Hybrid progenies of Fan 6, Chambord, Suwon 11, Kangyin 655, 7084 and chris in parent combinations had strong resistance to stripe rust; And most of hybrid progenies of Lovrin 10,13, Nouzucht, and et al were susceptible to stripe rust No. 29. Resistance to stripe rust of varieties from West China was higher than that of varieties from East China, and of in foreign materials Amimda and Ibeech et al had higher immunity.
