摘　　要：对黄河流域中熟杂交棉花区域试验参试品种进行分析和评价,可以为品种合理布局和品种性状改良提供科学依据。本研究利用GYT双标图对2022—2023年黄河流域30个参试品种的产量、品质、农艺性状、抗病性进行综合评价,深入分析皮棉产量与铃重、单株铃数、霜前花率、衣分、第一果枝节位、果枝数、生育期、株高、子指、纤维长度、断裂比强度、马克隆值、伸长率、整齐度、枯萎病指数、黄萎病指数等性状的组合水平,联合方差分析结果表明, 2年试验中所有性状的基因型效应和环境效应均达到了极显著水平,大部分基因型与环境互作效应达到了显著或极显著水平,同时大部分互作效应平方和占比总变异平方和比例大于基因型效应。筛选出中棉所9B07等产量-性状组合优良的品种,比对照品种中棉所9711适应性更广、丰产性更好,具有较高的应用推广价值。GYT双标图比GT双标图具有解释的变异比例更高、拟合度更好、分析结果可信度更高等优点,可以更加直观展示参试品种特点,为我国作物品种多性状综合评价提供参考。The analysis and evaluation of the regional cotton trials for medium-maturing hybrid varieties in the Yellow River Basin provide a scientific basis for optimizing varietal distribution and improving trait characteristics.This study comprehensively evaluated the yield,quality,agronomic traits,and disease resistance of 30 tested varieties in the Yellow River Basin from 2022 to 2023 using the GYT biplot method.An in-depth analysis was conducted on key traits,including lint yield,boll weight,number of bolls per plant,pre-frost yield rate,lint percentage,first fruiting branch node,number of fruiting branches,growth period,plant height,seed index,fiber length,fiber strength,micronaire,fiber elongation,fiber uniformity,Fusarium wilt index,and Verticil-lium wilt index.The joint analysis of variance showed that genotype and environmental effects were highly significant,and most genotype×environment interaction effects were significant or highly significant over the two-year experiment.Notably,the sum of squares for interaction effects exceeded that for genotype effects.Among the tested varieties,ZMS 9B07 demonstrated wider adaptability and higher lint yield compared to the control variety ZMS 9711.Compared to the GT biplot,the GYT biplot method exhibited a higher proportion of explained variation,better model fit,and greater reliability.This method more intuitively displays the characteristics of the tested varieties,providing a valuable reference for the comprehensive evaluation of multiple crop traits in China.
