Genotype-environment interaction analysis of the main quality traits of soft wheat in wheat area of Anhui province
To deeply study the interactive relationship between genotypic effects of the main quality traits and the en-vironmental effects of different planting regions and the relationship stability of soft wheat in wheat-growing areas of Anhui province,AMMI biplot was used to comprehensively evaluate four quality indicators such as protein content,wet gluten content,dough stabilization time and water absorption rate,of 12 soft wheat varieties planted in seven ecological pilot sites in this study.The analysis results of the AMMI biplot indicated that,ecological test sites of Suixi and Xinmaqiao could dis-tinguish the wet gluten content of different varieties well.The best location for distinguishing dough stability time of varieties was Taihe ecological test site.Fuyang cological pilot site could distinguish the water absorption rate of different varieties well,and the appropriate ecological site for dis-tinguishing protein content was Xinmaqiao.The varieties that performed well in water absorption rate and dough sta-bilization time were Ruihuamai 516 and Tianyikemai 5.The most stable varieties in terms of wet gluten content were Huacheng 863 and Ruihuamai 516.Tianyikemai 5 had a relatively high and stable average protein content.In comparison,Tianyikemai 5 has a widely adapted,stable and high-quality genotype.
