| 摘 要： | 采用灰色关联分析法对2007年牡丹江烟区3个主栽烤烟品种农艺性状与经济指标间的关联度进行了分析,以探讨农艺性状与经济指标之间的关系.结果表明:与烟叶产量关系最密切的因素是叶数、最大叶长和株高,其次是最大叶宽、茎围;与产值关系最密切的因素是叶数、株高和最大叶宽,其次是茎围和最大叶长;而农艺性状对均价、上中等烟、上等烟比例的关联度的大小顺序均为:最大叶长、株高、茎围、叶数、最大叶宽;因此,在烤烟品种的优质选育和高产栽培中,应注意叶数、株高、最大叶长等农艺性状的选育,并兼顾其他有利生物学性状的选择,进而提高育种效率. |

| Abstract: | The gray correlation degree was applied to reveal the relationship between agronomic characters and economic indexes of the 3 Major flue-cured tobacco varieties in Mudanjiang in 2007.The results indicated that the closest factors to yield were number of leaf,the maximum leaf length and the plant height,followed by the maximum leaf width and stalk circumference.The closest factors to quality were number of leaf,the maximum leaf width and the plant height,followed by the stalk circumference and maximum leaf l... |
