摘　　要：对 11个小麦品种 (系 )植株展开度、穗幅宽与产量性状的关系进行了研究。结果表明 ,植株展开度、穗幅宽与子粒产量的表型和遗传正相关达极显著水平。通径分析进一步说明 ,植株展开度、穗幅宽对产量的效应主要是通过生物产量、收获指数和穗粒重而起作用 ,该二性状测定方法简单 ,可作为高产育种的参考指标。The relationship among plot spike width,plant spread angle and yield traits in 11 wheat varieties was studied.The results showed that the phenotypic and genetic correlations among plot spike width,plant spread angle and yield were all positively significant at 1% level.Path analysis further showed that the total effect on yield of plot spike width and plant spread angle was basically by biomass,harvest index and spike grain weight.Plot spike width,plant spread angle measured simply and can be regarded as important criteria of selecting in high yield breeding.
