| 摘 要： | 对14个烤烟品种的株高、百叶重、叶龄、节距、腰叶长、腰叶宽等6个农艺性状与产量进行了灰色关联度分析.结果表明,各农艺性状与产量的灰色关联度大小依次为:株高、百叶重、叶数、节距、腰叶长、腰叶宽.因此在烤烟高产育种和高产栽培中,应当侧重株高、百叶重和叶数等农艺性状,并兼顾其他有利生物学性状的选择.

| Abstract: | Based on the theory of gray correlation system,correlativity between yield and the six agronomy characters of fourteen flue-cured tobacco varieties was analyzed.The results showed that the relational grade was as follows: plant-height,weight per one hundred leaves,the number of leaves,the length of internode,length of waist leaves and width of waist leaves.Plant height,weight per one hundred leaves and the number of leaves are more important than other traits in flue-cured tobacco high yield breeding,while other good biological options should be taken into account. |
