| 摘 要： | 利用DUS测试中的47个性状对15份普通玉米自交系和13份糯玉米骨干自交系进行了形态多样性研究。结果表明:本研究所选用的普通玉米自交系较糯玉米自交系的形态变异更为丰富;47个性状的Shannon-Weaver多样性指数存在较大差异。聚类分析表明,糯玉米自交系紧密地聚在一起,与普通玉米自交系存在较大形态差别。DUS测试性状涵盖的信息量大且受环境影响相对较小,可应用于玉米自交系的形态多样性分析。

| Abstract: | 47 DUS testing traits were used to investigate the phenotypic diversity of 15 common maize inbred lines and 13 elite waxy maize inbred lines.The results indicated that the common maize inbred lines were more diverse than the waxy type at the phenotypic level;the Shannon-Weaver diversity index between 47 traits varied widely.Clustering analysis showed waxy inbred lines clustered together tightly,and they had great phenotypic difference with common maize inbred lines.DUS testing traits can be used in the phen... |
