Abstract:

The study aims to evaluate the changes of the main traits of winter wheat in the Huanghuai dryland regional test and the relationship between the traits, and fully explore the utilization rate of the big data of traits in the regional trial and the possibility of using succession characteristics to improve the breeding accuracy of the selected traits, thus providing support of trait selection in wheat breeding. 16 apparent quantitative traits collected from tested varieties in the Huanghuai winter wheat dryland region in the year 2000-2015 were summarized and classified. Taking the yield traits, broad tolerance traits, and quality traits as the three index traits, based on the grouping of regional test, the differences in traits and performance trends of two kinds of tested cultivars were compared, and simple correlation analysis and typical correlation analysis method were used to study the general traits (sub-traits or indirect traits for breeding-assisted selection) and target traits (required traits of variety approval direct inspection) of the tested lines. Typical trait factors and their effects on selection and evaluation of dryland wheat breeding traits were analyzed to improve the selection of excellent traits.
