1979～1983年,在浙江舟山大麦黄花叶病重病田,连续3年重复鉴定了国内外大麦品种资源6026份,抗病材料经过多点10次以上鉴定,筛选出不发病或免疫材料36份,高抗材料24份,可作抗源之用。通过大量品种抗病性鉴定资料的统计分析证明,大麦对黄花叶病的抗性,多棱大麦比二棱大麦强,皮大麦比裸大麦强,六棱皮麦同其他各类棱型比较,抗性最强。已筛选到的抗源材料大部份原产于我国,并集中分布在长江中、下游的江、浙、鄂、赣四省。国外抗源材料以日本品种中出现的频率最高。 From 1979 to 1983, 6,026 barley varieties of domestic and foreign germplasm resources were repeatedly identified for three consecutive years in Zhoushan barley yellow mosaic disease serious disease field in Zhejiang Province. After more than 10 times of disease resistance materials were identified, 36 non-diseased or immunized materials were screened, High anti-material 24 copies, can be used as a source of resistance. Through the statistical analysis of a large number of varieties of disease resistance identification data, the resistance of barley to yellow mosaic leaf, polygonal barley stronger than the two barley, barley barley stronger than bare barley, six-sided leather compared with other types of prism, Most resistant. Most of the anti-source materials that have been screened originate in China and are mainly concentrated in the four provinces of Jiangsu, Zhejiang, Hubei and Jiangxi in the middle and lower reaches of the Yangtze River. Foreign anti-source materials in Japan varieties appear the highest frequency.
