小麦品种产量和品质性状相关的研究

选用２５个小麦品种，分析了其产量性状和品质性状的变异和相关，结果表明：籽粒产量与生物量和收获指数极显著正相关；生物量与收获指数无明显相关；ＳＤＳ沉降值、蛋白质含量、湿面筋含量及硬度间显著或极显著正相关；各品质性状与籽粒产量、生物量呈明显负相关，与收获指数等无明显相关。

Correlation between Yield and Quality Traits in Wheat Varieties

Twenty five wheat varieties were selected to analysis the variation of yield and quality traits and their correlations.Grain yield high significantly and positively correlated with biological yield and harvest index;Biological yield had no association with harvest index;There were significant and positive correlations among SDS sedimentation volume,protein content,wet gluten content and grain hardness;These quality traits significantly and negatively correlated with grain yield and biological yield,and had no correlations with harvest index and orther yield components.
