| 摘 要： | 目的]了解小麦上三叶性状与产量及其构成因素的关系。方法]选用10个优产小麦品种（系），采用相关及回归分析方法，分析了小麦上三叶与产量构成因素问的相关性。结果]结果表明，小麦上三叶性状与穗粒数，千粒重，穗粒重和产量等性状间的相关系数分别达到了显著或极显著水平。最后，建立了上三叶性状与产量及其构成因素的最优多元回归分析方程。结论]为西南地区小麦高产、稳产提供了参考，为小麦育种提供了理论依据。

| Abstract: | Objective]The research aimed to understand the relationship between the traits of top-three leaves and yield and its compositions of wheat.Method]Choosing 10 genotypes of high-yield wheat,the relativity between the traits of top-three leaves and yield and its compositions of wheat was analyzed by correlation analysis method and regression analysis method.Result] The results showed that the relationship between the traits of top-three leaves and grains per spike,1 000-kernel weight,grain weight of spike,yield were significant or most significant.And the multiple regression equations were founded in top-three leaves traits and yield traits.Conclusion] The study provided the reference for high yield and steady yield of wheat in southern area,and provided the theoretical basis for wheat breeding. |
