| 摘 要： | 利用灰色关联度法和相关分析法,对7份苜蓿雄性不育材料的单株种子产量及其与7个主要产量性状的关系进行了分析.结果表明:单株种子产量与各产量性状关联度的大小顺序为:生殖枝数>花序数/枝>株高>种子数/荚>千粒重>小花数/花>荚果数/花序.其中对苜蓿雄性不育杂交制种产量影响最大的因素是单株的生殖枝数,其次是花序数/枝和株高,这为提高雄性不育系的种子产量提供了理论依据.

| Abstract: | The correlation of single plan seed yield t and main yield traits of 7 alfalfa male sterile was studied with the analysis of grey correlation degree and correlation analysis.The results showed that the sequence of every main yield traits correlation degree and single plant seed yield behaved:number of reproductive branch>inflorescence number/branch>plant height>seed number/pod>1000-grain weight>floret number/inflorescence>pod/inflorescence.The number of reproductive branch of single plant was the most influ... |
