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。
The contribution of kernels to yield is decreased by sink-limiting treatment. However, the contribution of kernels number and kernel weight exceeds the number of ear in the source-reducing treatment.
限库处理降低穗粒数对产量的贡献，减源处理下穗粒数和粒重对产量的贡献超过穗数。
The result of multiple regression showed that ear diameter, ear rows, 1000 kernel weight and plant height with grain yield were significant.
逐步回归表明：穗粗、穗行数、千粒重、株高对产量的影响达到显著水平。
The variations of grain filling period, 1000 kernel weight, plant height and ear height with latitude and altitude were studied using 6 medium maturing maize varieties grown in Southwest China.
对6个中熟玉米品种在我国西南地区不同纬度和海拔高度的灌浆期、千粒重、株高和穗位高的变异与纬度和海拔的关系进行了分析。
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。
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.
