新疆春小麦种质资源农艺性状和品质性状的遗传多样性分析
Analysis of Genetic Diversity of Xinjiang Spring Wheat Agronomic Characters and Quality Characters
摘要
Abstract
[Objective]The research aimed to understand the genetic basis of 82 spring wheat germplasm resource. [Method]This paper determined 8 agronomic characters and 6 quality characters of 82 shares of spring wheat, and made statistical and cluster analysis of teat results. [ Result ] Diversity index of agronomic characters was from 0.900 to 0.814, coefficient of variability was from 11.21% to 30. 82% , diversity index of quality characters was from 0.709 to 0.878,coefficient of variability was from 38.06% to 8. 53% ; basing on the cluster analysis of agronomic characters at 3. 93, all the provided materials were grouped into 6 main classes and 8 subclasses. They were grouped into 5 main classes basing on the cluster analysis of quality characters at 3. 98. [ Conclusion ] The results indicated that there existed more extensive genetic diversity between provided wheat varieties.关键词
