Abstract: To evaluate the high yield,stable yield and adaptability for analyzing the genotype and environment interaction of new wheat cultivars under different ecological conditions,and to analyze the variation rule of yield of new wheat cultivars could provide scientific reference for the selection and breeding of wheat varieties with high quality.Regional trial was participated at Shangqiu, Luoyang and Xinxiang City in 2018-2020, with eight winter wheat cultivars as material, which were planted in Henan Province,mathematical statistics and GGE biplot were used to analyze the high yield,stability and adaptability of the new wheat varieties.Variance analysis showed that years,locations,cultivars and their interactions,except for years×cultivars,had extremely significant effects on wheat yield(P <0.01),and the years and locations had a greater contribution rate to wheat yield,38.63% and 32.86% respectively,while contribution rates of locations×cultivars,cultivars and years×cultivars to wheat yield was the smallest, only 1.31%. The yield of winter wheat in 2019-2020 was decreased by 9.71% compared with that in 2018-2019, the Shangqiu location had the lowest average yield for two years, which was significantly lower than the average yield of Luoyang and Xinxiang locations. The average yield of eight wheat cultivars from three regional test sites across two years were 8 049.04 kg/ha, yield of Taihe 896 had the highest, while yield of Bainong 207 had the lowest. In terms of high yield,Taihe 896,Nongkeda 888,Shengke 188,Hemai 53,Zhiyou 33,Yanbo 369 and Puda 1030 were varieties with better yield.In terms of stability,Bainong 207,Hemai 53,Nongkeda 888 and Zhiyou 33 were varieties with better yield stability.In terms of adaptability,Nongkeda 888,Taihe 896 and Shengke 188 were varieties with better adaptability.The research results provide a scientific basis for the rational utilization of new wheat varieties and have certain reference value.
