基于GGE双标图的北方地区鲜食糯玉米产量和品质性状及试点鉴别力分析

Analysis of Yield,Quality Traits and Testing Site Discrimination of Fresh Waxy Corn in Northern China Based on GGE Biplot

为筛选优良糯玉米品种,为其在北方代表生态区种植与推广提供理论依据与参考,通过GGE双标图法对北方鲜食糯玉米区试产量等性状和试点鉴别力进行分析。结果表明,郑白甜糯9号和天贵糯932是兼丰产性、稳产性和广适性的优良品种,万糯188、珍旱2019和京科糯617丰产性较好,稳产性略差。产量―品质性状功能图分析表明,万糯188、天贵糯932、京科糯617和郑白甜糯9号是综合表现优良的品种。筛选出内蒙古赤峰市和新疆石河子市是鉴别力和代表性较强的试点,可以用其选择优良品种,淘汰不稳定品种。

In order to screen excellent waxy corn varieties and provide theoretical basis and reference for its planting and popularization in the representative ecological areas in the north,the yield and other characteristics and pilot discrimination of fresh waxy corn in the north were analyzed by GGE biplot.The results showed that Zhengbaitiannuo 9 and Tianguinuo 932 were excellent varieties with high yield,stable yield and wide adaptability,while Wannuo 188,Zhenzao 2019 and Jingkenuo 617 had better high yield and slightly worse stable yield.Functional diagram analysis of yield-quality traits showed that Wannuo 188,Tianguinuo 932,Jingkenuo 617 and Zhengbaitiannuo 9 were the varieties with excellent comprehensive performance.Screening out the pilot sites with strong discrimination and representativeness were Chifeng city and Shihezi city,which could select excellent varieties and eliminate unstable varieties.
