摘　　要：为评价长江中下游地区籼稻稻瘟病抗性以及丰产适应性和稳定性,采用GGE双标图对13个中籼迟熟水稻品种在长江中下游16个试验点的产量数据及稻瘟病抗性数据进行综合分析。结果表明:‘爽两优粤农丝苗’平均产量为0.95kg/hm^(2),产量稳定性好,稻瘟病抗性鉴定指数3.2,是长江中下游地区高产、稳产、且对稻瘟病高抗的中籼迟熟品种;‘春9两优70’平均产量高,可达0.97kg/hm^(2),稳定性中等,稻瘟病抗性高,其鉴定综合指数为3.3,该品种在湖南岳阳、湖北黄冈和安徽芜湖的产量表现均较好,产量分别达1.09、1.16和1.06kg/hm^(2),具有广泛的适应性。‘深和两优1133’产量也较高,可达0.93kg/hm^(2),但稳定性差,稻瘟病抗性鉴定综合指数平均为4.0,对环境敏感性强,适合在特定的地点如江西高安、福建建阳、浙江温州等地种植。通过GGE双标图对试验地点进行综合评价,湖北武汉、湖北黄冈、安徽休宁、江西吉安和浙江温州对参试品种的区分力较强、生态区的代表性好,是较理想的试验地点。In order to evaluate the most stable rice blast resistance and its stability and high yield adaptability in the middle and lower reaches of the Yangtze River,the yield data and rice blast resistance data of rice varieties were comprehensively analyzed based on GGE biplot.A total of 13 medium Indica rice varieties planted in 16 test sites of the middle and lower reaches of the Yangtze River were selected.The results showed that:The average yield of Shuangliangyouyuenongsimiao'was 0.95 kg/hm²and the comprehensive index of identification was 3.2.It was an ideal variety with high yield,good stability,and high resistance to rice blast.The average yield of Chun 9 Liangyou 70'0.97 kg/hm^(2)was high with medium stability and strong resistance to rice blast.Its comprehensive index of identification was 3.3.This variety has the best yield performance in Yueyang of Hunan,Huanggang of Hubei and Wuhu of Anhui,reaching 1.09,1.16 and 1.06 kg/hm^(2),respectively.This variety showed the best yield performance in multiple locations,which meant an ecologically adaptable variety.The yield of‘Shenheliangyou 1133'0.93 kg/hm^(2)was higher,but it was low stability and sensitive to the environment.The average comprehensive index of rice blast resistance identification was 4.O.This variety was suitable for promoting planting in specific locations such as Gao'an,Jianyang,Wenzhou,etc.The ideal test sites selected for comprehensive evaluation based on GGE biplot were Wuhan,Huanggang,Xiuning,Ji'an and Wenzhou because these sites had strong differentiation of varieties and good representation of ecological regions.
