在广西、湖南、北京进行白叶枯病抗病性同步鉴定,将1574份云南稻种分为15个抗病类型。筛选出抗病品种41份,占总数的2.6%,其中海南糯对25个菌株表现广谱抗性,并对Bs-3和Ks-6-6两菌株表现全生育期抗性。云南稻种籼粳间抗病性差异显著。对白叶枯病的抗性与原产地海拔高度呈负相关。
In Guangxi, Hunan and Beijing, simultaneous identification of bacterial blight resistance was carried out, and 1574 Yunnan rice cultivars were divided into 15 types. Thirty-one resistant varieties were screened out, accounting for 2.6% of the total. Among them, Hainan had waxy broad-spectrum resistance to 25 strains and resistance to Bs-3 and Ks-6-6. Differences in resistance between indica and japonica rice varieties in Yunnan were significant. The resistance to bacterial blight was negatively correlated with the altitude at the origin.
