Comprehensive analysis of main characters of new wheat series
In order to make good use of wheat germplasm resources and materials to further understand the relationship between yield and main traits of Xinmai series varieties,11 main agronomic and quality traits of 27 Xinmai series wheat varieties were analyzed.The results showed that the variation range of quality traits was large,among which the coefficient of variation of stability time was the largest,the genetic variation degree of germplasm resources was high,and the genetic basis was richer,and there was a complex correlation between agronomic traits and quality traits,and there were 8 pairs of traits that were significantly or extremely significantly correlated,with 1 000-grain weight and yield being significantly positively correlated,protein and wet gluten and water absorption,protein and stabilization time being significantly positively correlated,and there was no obvious constraint relationship between yield and quality traits.According to agronomic traits and quality traits,the tested materials can be clustered into five groups,group Ⅱ can be used as the resource material for improving panicle characteristics in breeding,group Ⅲ can be used as dwarf straw lodging resistance and early maturing materials,and the varieties in group Ⅴ are all high-quality strong gluten varieties,which can be used as high-quality strong gluten and high-yield resources in breeding.
