用GGE双标图分析广西旱藕品种产量稳定性和试点代表性

The yield stability and site representative of canna varieties in Guangxi using GGE biplot

为了筛选适合广西种植的旱藕新品种,用GGE双标图分析了5个旱藕品种在广西4个不同海拔区域的产量稳定性和试点代表性。结果表明,兴芋3号属高产稳产型;兴芋2号稳定性好,产量较高;田林旱藕产量最低,稳定性较差;马山旱藕产量较高,但稳定性差。从品种对试点的特殊适应性分析,兴芋3号特殊适应性最广。从产量水平来看,兴芋3号表现较好,其次为兴芋2号,可加大力度推广。田林县和大化县试点区分能力强,都安县试点代表性较好。

In order to screen the new canna varieties suitable for plantation in Guangxi,the GGE biplot was used to analyze the yield stability and test site representatives of five canna varieties in four different altitude regions. The results showed that Xingyu 3 was a type of high and stable yield. The stability of Xingyu 2 was good with high yield.The yield of Tianlin canna was the lowest with poor stability. The yield of Mashan canna was higher,but its stability was poor. The special adaptability analysis of varieties in the test sites showed the special adaptability of Xingyu 3was the widest. From the yield point of view,the performance of Xingyu 3 was good,followed by Xingyu 2,which should be greatly promoted. Tianlin and Dahua sites had the best discrimination,while Du＇an site had the best representativeness.
