[目的]寻求小麦高产和超高产育种的关键指标。[方法]以安徽省种植的10个小麦品种(系)为试验材料,研究不同品种(系)的产量与产量构成因素(有效穗数、千粒重、穗粒数、穗粒重、单位面积粒数、穗长、结实小穗数、不实小穗数)、生物学产量、株高、收获指数等性状之间的相关性。[结果]产量与其他若干性状在相关方向和程度上均有差异,且其他性状之间相关性及差异显著性均有不同;大多数品种(系)的产量与产量构成因素中的生物学产量及穗粒重显著相关,同时某些品种(系)的产量与其他性状之间显著相关。[结论]以产量作为小麦高产及超高产育种的选择指标之一是有效的。
[Objective] The research aimed to seek the key indexes of wheat with high yield and super high yield. [Method] Ten wheat varieties (lines) planted in Anhui Province were used as experimental materials to study the effects of different varieties (lines) on yield and yield components (effective panicle number, 1000-grain weight, , Spike length, number of spikelets, number of spikelets), biological yield, plant height, harvest index and other traits. [Result] The yield and some other traits were different in the direction and degree of correlation, and the correlations and the differences were significant among other traits. The yield of the most cultivars (lines) and the biological yield of yield components And grain weight were significantly correlated, while some varieties (lines) yield and other traits significantly correlated. [Conclusion] Taking yield as one of the selection indexes of wheat high yield and super high yielding breeding was effective.
