本文对3种类型30个冬小麦品种的15个性状与抗旱性、产量的关系,进行了相关分析和通径分析。认为良好的群体结构和高度的抗寒性是旱地冬小麦抗旱性和丰产性的基础性状。稳定穗数,提高穗粒数和千粒重则是进一步提高旱地小麦产量的有效途径。
In this paper, the correlation analysis and path analysis of 15 traits of 30 winter wheat cultivars with drought resistance and yield were conducted. It is considered that good population structure and high degree of cold tolerance are the basic traits of drought resistance and high yield of winter wheat in dryland. Stabilizing the panicle number, increasing the number of grains per spike and 1000-grain weight are the effective ways to further improve the wheat yield in dryland.
