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。 From 1997 to 1999, the field resistance of powdery mildew from 180 barley germplasm resources in Sichuan Province was identified. Six resistant germplasm resources were obtained from Sichuan Province, 57 of the quality resource materials; the relative proportions of the resistant and the medium resistant materials in rye and polygamous barley germplasm resources were relatively large, and there were both the resource materials with early maturity and disease resistance, and the resistance germplasm resources origin of.
