17份冬小麦品种农艺性状的相关分析及聚类分析

为了更有效探明小麦主要生物性状与产量之间的相关性，试验采用相关分析及聚类分析对 17个小麦品种的7个农艺性状进行调查、归类分析。结果表明：产量与收获穗数的关联系数值为0.59，水平达到显著，小穗数和穗粒数之间的关联系数为0.79,水平达到显著；收获穗数对产量的影响最大，收获穗数的提高对产量增加起到关键的作用。通过聚类分析将17个小麦品种划分为5大类群。17份塔额盆地小麦新品种农艺性状具有丰富的遗传多样性，变异幅度大；根据育种目标的不同，可选择不同类型的小麦品种作为亲本，同时推动了塔额盆地小麦品种改良工作，为选配亲本提供了科学依据。

Correlation Analysis and Cluster Analysis of Agronomic Traits of 17 Winter Wheat Cultivars

To effectively explore the correlation between the main biological traits of wheat and yield, correlation analysis and cluster analysis were conducted to investigate and classify 7 agronomic traits of 17 wheat varieties. The results showed that the correlation coefficient between yield and ear number was 0.59, and the correlation coefficient between spikelet number and ear number was 0.79. The analysis results showed that the number of harvested ears had the greatest effect on yield.The increase in harvested ear number played a key role in the increase of yield. The 17 wheat varieties were divided into 5 major groups by cluster analysis. The agronomic traits of these 17 new wheat varieties in the Taehe Basin had rich genetic diversity and substantial variation. Depending on different breeding goals, different types of wheat varieties can be selected as parents, and the improvement of wheat varieties in the Tage Basin is promoted, which provides a scientific basis for the selection of parents.
