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。
The genetic correlation among eight quality traits, such as amylose content, gel consistency, alkali consumption, protein content, grain length, grain width, aspect ratio and 1000-grain weight, were studied. The effects of amylose content, Value and protein content of four quality traits and the spike number per panicle, grain number per spike, 1000-grain weight and yield per plant and other four yield traits between the genetic correlation. The results showed that there was some genetic correlation between any two quality traits and between quality traits and yield traits. Some traits showed more complicated genetic correlations, more than two kinds of genetically related components, while others The genetic correlation between traits is relatively simple, there is only one or two genetic related components.
