对新铁炮百合 17个株系主要性状的变异进行了观察 结果表明 ,所观测的大部分性状在株系间存在显著或极显著差异 根据选育的主要性状 ,综合水平较好的株系为 1、2、6、8、9、10、17 同时对 17个株系进行聚类分析 ,表明株系间遗传距离差异大 ,最大的为 51.4 18,最小的仅 2 .94 9,根据遗传距离将 17个株系分为 3大类 认为该百合分离群体具有较丰富的遗传变异性 ,是新品种选育的良好基础群体
The variation of major traits in 17 lines of Lilium regia Lilium was observed. Most of the traits observed showed significant or extremely significant differences among the lines. According to the main characters of breeding, the lines with better overall level were 1, 2, 6, 8, 9, 10 and 17 clustering analysis of 17 lines at the same time showed that the genetic distance between the lines varied greatly, with the largest being 51.418 and the smallest being only 2.949. According to the genetic distance The 17 strains were divided into three categories that the lily segregated population has a rich genetic variability, is a good breeding base for new varieties
