云南小麦品种抗条锈性测定初报

Preliminary Report of Test of Resistance to Stripe Rust of Wheat Varieties in Yunnan

利用条中31号、条中32号、水源11-14和Hybrid46-8等小麦条锈菌生理小种混合菌系对主要生产品种、优质专用小麦及拟推广品种、其它一些有苗头的高代材料共95个品种(品系、材料)进行苗期和成株期抗条锈性测定。结果表明:供试材料中14.7%表现全生育期免疫,24.2%表现成株期中—高抗,24.2%表现成株期中抗—中感,测定结果可为抗病品种的选育选用提供重要的依据。

Testing of the resistance to stripe rust of 95 wheat varieties indicates that 14.7% of the subjects showed immune in all growing period,24.2% showed mid to high resistant,and 24.2% others varied from mid resistant to mid susceptible at the adult plant stage. The tested varieties by using a mixture of CYR31,32,Shuiyuan 11-14 and Hybrid 46-8 include the main planting varieties,high quality varieties, spreading varieties and a number of prospective stocks. The results are expected to provide basic information for the breeding and using of resistant varieties.
