用GGE双标图分析贺油花生品种产量稳定性及试点代表性

Application of GGE-biplot analysis on yield stability and testing-site representativeness of Heyou-series peanut in southeast China

采用GGE-biplot双标图分析方法,分析了贺油系列花生品种在江西赣州,福建泉州,广东湛江、罗定,广西贺州、桂平、武宣的产量数据。结果表明:贺油11号、贺油12号具有较强的稳产性、高产性和适应性,其中贺油11号的平均产量、最高产量分别为3 510.7、4 447.5kg·hm^(-2),贺油12号的平均产量、最高产量分别为3 440.2、4 575.0kg·hm^(-2),除了贺油12号在贺州试点表现不佳外,这两个品种在其他试点中均表现良好;其余品种都有各自特殊的适应区域,贺油9号适合贺州试点所代表的区域种植,贺油10号适合广东罗定试点所代表的区域种植,贺油13号适合江西赣州和广东湛江试点所代表的区域种植;在各品种适应的种植区域中,它们的产量均高于3 410.0kg·hm^(-2)。GGE双标图分析方法对指导花生在不同生态环境条件下的选育和产量鉴定有一定的指导意义,为贺油系列花生品种选择有针对性推广区域提供了理论依据。

GGE- biplot was used to analyze the yield data of Heyou peanut tested in 7 sites including Ganzhou,Quanzhou,Zhanjiang,Luoding,Hezhou,Guiping,Wuxuan in South China. The results showed that Heyou11 and Heyou 12 had higher yield ability and stability than other Heyou cultivars. Average yield and the highest yield of Heyou 11 were 3 510. 7 kg·hm^-2and 4 447. 5 kg·hm^-2,and those for Heyou 12 were 3 440. 2,4 575. 0 kg·hm^-2respectively. Both Heyou 11 and Heyou 12 adapted to most sites tested,except Heyou 12 in Hezhou. The rest of the cultivars had their own special adaptive region. Heyou 9 was most suitable for planting in Hezhou,Heyou 10 in Luoding Guangdong,Heyou 13 in Zhanjiang Guangdong and Ganzhou Jiangxi,respectively. Their yields were higher than 3 410. 0 kg ·hm^-2in their adapted region. GGE- biplot method could provide a guideline on cultivar breeding and yield evaluation at different conditions,and this study could contribute to peanut expansion and peanut breeding of Heyou improvement.
