| 摘 要： | 运用典范相关分析方法,对西藏及周边地区芥菜型油菜的产量性状、主茎性状、分枝性状、角果性状等4组性状间的典范相关关系进行了比较研究.结果表明:(1)所研究的18个性状中,西藏芥菜型油菜的平均数为周边地区芥菜型油菜的1.88倍,总体变异系数比周边省份芥菜型油菜高10.22％；(2)西藏芥菜型油菜单株产量主要取决于每株角果数和千粒重,而周边省份芥菜型油菜单株产量主要取决于每株有效角果数,中国周边国家芥菜型油菜单株产量主要取决于每株有效角果数和千粒重；(3)影响西藏芥菜型油菜产量性状最重要的因素是角果性状,其次是分枝性状和主茎性状,而影响周边省份和中国周边国家芥菜型油菜产量性状最重要的因素则是主茎性状,其次是分枝性状和角果性状.

| Abstract: | Canonical correlation analysis were used for 4 agronomical traits including yield traits,the main stem traits,branching characteristics and pod traits of Brassica juncea species in Tibet and the Adjacent Regions.The results showed that :(1)Among the 18 traits investigated,the average value for Tibetan B.juncea species was 1.88 folds of that from the species in the adjacent provinces,and the population coefficient of variation was 10.22%and higher than that of the adjacent regions.(2)In the Tibetan B.juncea ... |
