| 摘 要： | 对1996年鉴定的30份感病品种(品系)含88个单株后代,以成株率为依据,测定一次性自然选择效果,用模糊数学的隶属函数值U(X)进行综合评判。表明同一材料株间感病性存在差异,群体抗病性趋与减弱。从感病的群体中可以选到抗病的单株后代。

| Abstract: | Based on the study of 30 susceptible breeds including 88 filial generations indentified in 1996, their lump sum natural selected effects were determined on the base of averege survival plant rate, and all breeds were evaluated comprehensively with fuzzy mathematics. Results showed that susceptibility to flax wilt for the same varieties is different among plants. Resistance to wilt for all samples tended to decrease and the resistant plants were selected in the susceptible linseed colony. |
