摘要:

为筛选适宜黄淮海麦区种植的优异冬小麦品种,本研究以60个冬小麦品种为试验材料,测定生育期、群体结构、产量构成及抗逆性等12项性状指标,采用主成分分析与聚类分析进行综合评价。结果表明,12项性状均存在显著差异,变异系数为1.4%~28.3%;产量与全生育期、最高分蘖、抽穗天数等呈极显著正相关,与综合抗病指数呈极显著负相关。通过主成分分析提取的5个主成分,其累积贡献率达77.517%,构建的综合评价模型可有效量化品种综合表现;综合得分前10名的品种,其平均产量达到11737.8 kg/hm2,比对照‘周麦36号’增产11.2%,可作为豫东麦区重点推广或高产攻关的核心品种。聚类分析将60个品种分为3个类群,明确了各类群的应用场景,其中Ⅰ类群中18个品种综合表现最优。本研究结果可为黄淮海麦区小麦品种的区域布局、生产应用及育种改良提供理论依据和实践指导。

Abstract:

To screen excellent winter wheat varieties suitable for planting in the Huang-Huai-Hai Wheat Region, 60 winter wheat varieties were used as experimental materials, and 12 trait indicators such as growth period, population structure, yield components and stress resistance were determined. Comprehensive evaluation was conducted by adopting principal component analysis and cluster analysis. The results showed that there were significant differences among the 12 traits, with the coefficient of variation ranging from 1.4% to 28.3%. Yield was extremely significantly positively correlated with the whole growth period, maximum tiller number and heading days, while extremely significantly negatively correlated with the comprehensive disease resistance index. Five extracted principal components accounted for a cumulative contribution rate of 77.517%, and the constructed comprehensive evaluation model could effectively quantify the comprehensive performance of varieties. The top 10 varieties in comprehensive score had an average yield of 11737.8 kg/hm2, which was 11.2% higher than that of ‘Zhoumai 36’ (control), and these varieties could be used as core varieties for key promotion or high-yield research in the Eastern Henan Wheat Region. Cluster analysis divided the 60 varieties into 3 groups, among which 18 varieties in group Ⅰ showed the best comprehensive performance, and the application scenarios of each group were clarified. The results of this study can provide a theoretical basis for the regional layout, production selection and breeding improvement of wheat varieties in the Huang-Huai-Hai Wheat Region.
