【摘要】 利用11个不同的小麦基因型,对克草粒数的基因型差异及其与产量性状的关系进行了研究。结果表明:克草粒数在小麦基因型间存在极显著差异,与经济系数的表型正相关和遗传正相关均达极显著水平,与生物产量呈弱的正相关,与籽粒产量的表型正相关和遗传正相关也达极显著水平。更多还原

【Abstract】 The 11 wheat cultivars under plot-cultivated condition were used in this experiment. The results showed that there were highly significant differences between various cultivars. The phenotypic and genetic correlations among G/W and harvest index, plot yield were all positively significant at 1% level, but the correlation between G/W and biomass was not significant.更多还原
