The gene effects of ear length, ear thickness, kernel rows per ear, hundred-grain-weight(H. G. W. ) and grain weight per plant were analyzed in a set of diallel crosses which involved 8 parents.
由8个亲本组成的双列杂交试验，分析了穗长、穗粗、穗行数、百粒重、单株籽粒产量的基因效应。
The results show that 1000 grain weight, rows per ear, ear diameter, kernels per row and kernel percentage have higher positive correlation with kernel yield and the first two are most important.
结果表明，所研究性状中千粒重、穗行数、穗粗、行粒数和出籽率等对籽粒产量有较大的正直接作用，并且以前两者最为重要。
Density is negatively correlated with number of kernel per ear and 1 000 grain weight.
密度与穗粒数和千粒重均呈线性负相关。
The number of ears per plant, the number of kernels per ear and 1000-kernel weight decreased as density increased. Grain yield and density showed a quadratic parabola relationship.
单株穗数、穗粒数和千粒重随密度增加而下降，籽粒产量与密度呈二次抛物线关系。
