Eurytopicity Analysis of'Zhongheyou1',an Indica-Japonica Hybrid Rice Va-riety Based on GGE Biplot
In order to evaluate the eurytopicity of'Zhongheyou1',an indica-japonica hybrid rice variety,the high yield,stability and adaptability were analyzed by using the yield data of 2017 to 2018 national medium indica late-maturing group A in the middle and lower Yangtze River based on GGE biplot.The high yield and stability analysis indicated that the yield of'Zhongheyou1'was 4.66％and 6.62％higher than that of the control in 2017 and 2018,respectively.In 2017,it showed the best yield performance in Chuzhou of Anhui Province,Yangzhou of Jiangsu Province,Jiujiang of Jiangxi Province and Hangzhou of Zhejiang Province.In 2018,it had an outstanding high and stable yield performance better than the control and the average environment in all the regional test sites.It was a variety type with both high yield and stability.The ideal variety analysis showed that'Zhongheyoul'had a pool ranking as the control in 2017.On the contrary,it was one of the closest combinations to the center of ideal variety.The'Which Won Where/What'polygon view indicated that'Zhongheyou1'was the'winner'in Chuzhou of Anhui Province,Yangzhou of Jiangsu Province,Jiujiang of Jiangxi Province,Hangzhou of Zhejiang Province and Wuhu of Anhui Province in 2017.It had special adaptability in these three regional sites.In 2018,it was most suit-able for planting in Huangshan and Hefei of Anhui Province,Nanping of Fujian Province,Xinyang of Henan Province,Yichang of Hubei Province,Yangzhou of Jiangsu Province,Jiujiang and Nanchang of Jiangxi Province.Comprehensive analysis indicates that,'Zhongheyou1'is one of the ideal varieties with high yield,stability and wide adaptability in the medium indica late-maturing group A of middle and lower Yangtze river.
