摘要
1997～ 1 999年对四川 1 80份大麦种质资源材料 (品种 )进行了白粉病的田间抗性鉴定 ,初步鉴定出来源于四川省境内的抗性种质资源材料 6份 ,中抗性种质资源材料 5 7份 ;裸麦、多棱大麦种质资源中抗性及中抗性材料相对比例较大 ,而且存在兼有早熟与抗病性的资源材料 ,同时还分析了抗性种质资源的来源。
During 1997 1999,180 materials(varieties) of barley germplasmic resources collected in Sichuan were examined in the field for their resistance to powdery mildew (Erysiphe graminis f.sp.hordei).Among these varieties,6were preliminarily identified as resistance,57 varieties as moderate resistance.The naked poly rowed barley varieties with resistance and moderate resistance accounteed for the major proportion in comparison with husked or two rowed ones,some varieties possessed both property resistance and early maturity.The origin of the resistant germplasmic resources were also analyzed.
