摘要
[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 study was aimed to seek the key indices for high-yield and super high-yield breeding of wheat. [Method]Ten wheat varieties （or lines）, which are suitable for cultivation under Anhui conditions, were chosen as the experimental materials to study the relation- ships between yield and yield components （ the number of spikes, grain weight, grain number, grain weight, grain nmnber per unit area, pike length, fruit spikelet number, spikelet number of abortive spikelet）, biomass, plant height, and the harvest index. [ Results] Coefficient be- tween yield and other traits varied in direction and degree was different. Among the studied agronomic traits, there were significant differ- ences. For most of the varieties （ or lines） studied, grain yield was significantly related to biomass and grain weight per spike. For some of the other varieties （or lines）, grain yield was significantly related to other parameters. [ Conclusion] Yield parameter itself can be adopted effec- tively in seleetin~ ootential hizh-vield and super hizh-vield wheat varieties.
