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。
It would deteriorate its ear characteristics, and decrease significantly ear kernel number and 100-kernel weight as well as economic yield of maize.
进而引起果穗性状恶化，穗粒数和百粒重减小，最终导致经济产量大幅下降。
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。
