摘要
为更合理评价籼粳交杂交水稻组合‘中禾优1号’的广适性,利用2017—2018年长江中下游中籼迟熟A组区试产量数据,对各参试品种(组合)进行丰产性、稳产性和适应性的GGE双标图分析。丰产性、稳产性分析表明:2017年、2018年‘中禾优1号’分别比对照增产4.66%和6.62%,2017年在安徽滁州、江苏扬州、江西九江和浙江富阳丰产性最好,2018年在所有试点均稳定的表现出优于对照品种和平均环境,丰产性突出,是既高产又稳产的品种类型。理想品种分析显示,‘中禾优1号’和对照品种2017年的排名较后,2018年是最接近理想品种的参试组合之一。“哪个赢在哪里”功能图分析表明‘,中禾优1号’是2017年安徽滁州、江苏扬州、江西九江、浙江富阳和安徽芜湖等试点内的“赢家”,具有特殊适应性;2018年在安徽黄山、安徽合肥、福建南平、河南信阳、湖北宜昌、江苏扬州、江西九江和江西南昌等8个试点内最适宜种植。综合分析表明‘中禾优1号’是长江中下游中籼迟熟A区试组内兼具丰产性与稳产性理想品种之一,具有广泛的适应性。
In order to evaluate the eurytopicity of‘Zhongheyou 1’,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‘Zhongheyou 1’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‘Zhongheyou l’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‘Zhongheyou 1’was the‘winner’in Chuzhou of Anhui Province,Yangzhou of Jiangsu Province,Jiujiang of Jiangxi Province and Hangzhou of Zhejiang Province,2017.It had special adaptability in these three regional sites.In 2018,it was most suitable 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.Comprehensively,‘Zhongheyou 1’is one of the ideal varieties with high yield,stability and wide adaptability in the medium indica late-maturing group of middle and lower Yangtze river.
