AMMI模型与BLUP方法相结合评价河北省冬小麦品种丰产性和稳定性
High yield and stability evaluation of winter wheat varieties in Hebei Province by combining AMMI model and BLUP method
摘要
Abstract
In order to effectively identify and evaluate the yield,stability and adaptability of winter wheat varieties in Hebei Province,and to select superior wheat varieties suitable for widespread cultivation in this region,a new variety evaluation system,namely WAASB(weighted average of absolute scores)and WAASBY(considers both stability(WAASB)and mean performance(dependent variable,Y))were employed.Comprehensive analysis was then conducted on the yield data of 14 trial varieties from the water-saving group in 10 test sites in Hebei Province during 2018-2019 winter wheat season.The AMMI(additive main effect and multiplicative interaction)model showed that environment effects were the main source of variation,followed by the interaction between genotype and environment,and genotype effects accounted for the smallest proportion.In terms of model diagnosis,AMMI 2 and GGE 2 were used as suitable models for the AMMI family and GGE models by FR test.The ratios of genotype and environment interaction(GE)signals and GGE signals accounted for 84.06％and 85.25％,respectively.The principal component analysis of various stability factors showed that the first two principal component axes collectively explained 78.5％of the variance.The grain yield was highly positively correlated with stability factors based on the mixed effects model and the geometric adaptability index.According to the GY x WAASB biplot,'HH1704''ZN202''ZX8482''MG729''JH16415'and'Sta14'were selected as the varieties with outstanding high yield and good stability.Among the selected varieties,'ZX8482'had the highest WAASBY score,which performed the best among the tested varieties,while'HK4242'had the lowest WAASBY score,which performed the worst.The suitable varieties to be promoted in Dacaozhuang,Shenzhou and Yongnian were'HH1704'and'ZN202'.The suitable varieties for planting in Handan and Luquan were'HK4242'and'MG729'.It was also found that variety'ZX8482'was suitable for planting in Shenzhou,Xinji,Xingtai and Yongnian.In conclusion,the use of the mixed linear model stability index(WAASB)and simultaneous selection index(WAASBY)can provide a basis for the demonstration and promotion of winter wheat varieties in Hebei Province.关键词
