应用GGE双标图分析湖北省玉米区域试验品种适应性和稳定性

Analysis of Adaptability and Stability of Maize Regional Trial Varieties in Hubei Province by Using GGE-Biplot

以湖北省2009年玉米(Zea mays L.)区域试验数据为例,介绍了GGE双标图在评价玉米品种适应性、稳产性、丰产性以及试验点的鉴别力和代表性的运用。结果表明,Hk9509、Sx0759、Hz06148、Kn0901共4个品种的丰产性、稳产性较好;宜昌市、长阳土家族自治县、建始县地点鉴别力较大;恩施市、仙桃市、长阳土家族自治县地点代表性较强;综合地点鉴别力和代表性分析,长阳土家族自治县和宜昌市试验点较好。

A regional variety test with maize(Zea mays L.)in Hubei Province in 2009 as an example,the application of GGE-Biplot in evaluating the variety of adaptability,yield-ability,stability and the locations of identification and representativeness was introduced.The results of analysis showed that Hk9509,Sx0759,Hz06148 and Kn0901 possessed high stability and productive level.Yichang,Changyang Tujia autonomous county and Jianshi county possessed high distinguishability.The locations of Enshi,Xiantao and Changyang Tujia autonomous county possessed high representativeness.Based on the location distinguishability effects and representativeness of the variety was estimated.As a result,Changyang Tujia autonomous county and Yichang are more appropriate locations.
