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间的相关性。[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。
[ 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.
