基于R语言GGE双标图的河南省弱筋小麦区试品种的丰产性和稳定性分析

Analysis of Yield and Stability of Weak Gluten Wheat Varieties in Henan Based on R Language GGE Biplot

利用GGE双标图综合评价2017-2018年2年河南省弱筋小麦区试品种基因型及基因与环境的互作效应。结果表明,2017年中‘森科09-3’和‘信麦1168’均表现出优良的丰产稳定品质,2018年中‘太学766’是具有广泛适应性的优良品种。试点评估中,2017年的8个试点和2018年的6个试点均被划分为3个生态亚区。其中,2017年兼具区分力和代表力的试点是信阳,而光山是2018年所有试点中代表性和区分力最强的理想试点,可以用于筛选丰产稳产小麦品种。GGE双标图为小麦新品种选育评价、试验点评价选用等方面提供更直观高效的评价方法和参考价值。

This study utilized the GGE biplot to comprehensively evaluate the genotypes of weak gluten wheat cultivars and the genotype-environment interaction effects in Henan Province during the 2017–2018 growing season.The results indicated that'Senke 09-3'and'Xinmai 1168'exhibited excellent and stable yield characteristics in mid-2017,while'Taixue 766'was identified as an excellent variety with broad adaptability in mid-2018.In the pilot evaluations,eight sites in 2017 and six sites in 2018 were categorized into three ecological subzones.The Xinyang site in 2017 demonstrated both distinguishing and representational strengths,while Guangshan emerged as the ideal site in 2018,showing the strongest representational and distinguishing capabilities among all sites.This site can be utilized for screening high-yielding and stable wheat varieties.The GGE biplot provides a more intuitive and efficient evaluation method and offers valuable references for the assessment of new wheat varieties and trial site selection.
