| 摘 要： | 用8个稻瘟病菌稳定菌系,将969个籼稻品种(组合)区分为9个群106个品种型,其中籼A群1号,有166个品种,出现频率最高,抗8个稳定菌系,为主要品种型。在籼A1品种型中选出68个有代表性品种,再用分属于18个小种的30个菌株作了抗谱测定。从中选出一些抗谱广、抗性稳定的抗源品种和可在生产上推广试用的抗病、高产良种(组合)。

| Abstract: | 8 stable strains were screened from 950 cultures of Pyricularia oryzae isolated in China. 969 indica rice varieties (combinations) can be distinguished into 9 variety-groups and 106 variety-types based on their reaction to the 8 stable strains. Among them,XA1 was the principal variety type appeared in high frequency.68 varieties selected from XA1 were inoculated with 30 strains belong to 18 races. Some varieties were screened out for their broadest resistant spectrum and resistant stability. They could be used as the resistance source for breeding and the resistant cultivars (combinations) for agricultural production. |
