| 中文摘要: |
| 为了充分了解新疆冬小麦地方品种农艺性状的遗传多样性，以117份新疆冬小麦地方品种为材料进行13个农艺性状和2个品质性状的比较分析。结果表明，新疆冬小麦地方品种主要农艺性状存在丰富的变异：各性状的变异系数为6.54%～52.41%，Shannon多样性指数为1.812～2.656。15个性状变异系数按大小排列依次为：不育小穗数（52.41%）>有效分蘖数（34.98%）>总分蘖数(31.25%)>穗粒重(29.52%)>旗叶长度(23.57%)>千粒重(18.28%)>穗粒数(17.94%)>株高(15.15%)>旗叶宽度(14.29%)>小穗粒数(12.62%)>穗长(12.39%)>每穗小穗数(11.93%)>小穗着生密度(11.55%)>湿面筋含量(7.67%)>蛋白质含量(6.54%)。性状间简单相关分析中有24对性状相关极显著，其中旗叶长度、旗叶宽度、株高、分蘖数、有效分蘖数等性状与穗长、小穗粒数、穗粒数、穗粒重、千粒重以及蛋白质含量、湿面筋含量都有较大的相关性。聚类分析将参试的117份资源聚为6类。 |
| 英文摘要: |
| This article analyzed and compared the genetic diversity in 13 agonomic traits and 2 quatitative traits of winter wheat landrace varieties in Xinjiang.The results showed that there were abundant diversity among main agriculture traits of different varieties.Variation coeffient of thirteen agonomic traits and two quality traits was 6.54%～52.41%, diversity index cofficient was 1.812～2.656. The results indicated that there were 24 pairs of characters with significant correlations in simple correlation analysis,respectively. The results of cluster analysis with average genetic distance showed that 117 landrace varieties could be divided into six groups with different characteristics in the study,which could afford reference in winter wheat breeding. |
