摘要
研究了直链淀粉含量、胶稠度、碱消值、蛋白质含量、粒长、粒宽、长宽比和千粒重等 8个品质性状之间的遗传相关 ,以及直链淀粉含量、胶稠度、碱消值和蛋白质含量等 4个品质性状与单株穗数、穗实粒数、千粒重和单株产量等 4个产量性状之间的遗传相关。结果表明任两个品质性状之间及品质性状与产量性状之间均存在某种遗传相关 ,其中有的性状之间表现为较复杂的遗传相关 ,存在两种以上的遗传相关分量 ,而另一些性状之间的遗传相关较为简单 ,仅存在一、二种遗传相关分量。
Deals with genetic correlations among the quality traits of seeds, such as amylose content, gel consistency, alkali digestion, protein content, grain length, grain width and 1000-grain weight, and genetic correlations between the quality traits and yield traits, such as effective number of panicles per plant, plumped number of grains per panicles, 1000-grain weight and grain yield per plant. The results indicated that genetic correlation components were observed among the quality traits, also observed between the quality traits of seeds and agronomic characters of their maternal plants. In the genetic correlations among some of the traits there were more than two genetic correlation compoments, which showed the complex nature of their relationship. But the genetic correlations among other traits were simple, only one or two genetic correlation components appeared.
