小麦株高、穗幅宽和植株展开度的研究

A Study on Height, Plot Spike Width and Plant Spread Angle in Wheat

对 1 0个小麦品种 (系 )的株高、穗幅宽、植株展开度进行了研究。结果表明 ,株高、穗幅宽、植株展开度与产量的表型相关均达极显著水平 ,穗幅宽与产量的遗传相关也达显著水平 ,以上三性状的遗传力和选择效果较高 。

This study was conducted with 10 genotypes of winter wheat. There were significantly negative correlations between grain yield and height, between yield and plot spike width, and plant spread angle. These characters were provided with high hereditability and correlative genetic advance, and can be regarded as important criteria of selection in high-yield-breeding.
