摘要: 为了合理利用春小麦种质资源,给小麦新品种选育提供材料,对30份供试材料的9个农艺性状进行主成分分析和聚类分析。结果表明,有效分蘖数、生物产量、单株产量、穗粒数、穗长、千粒重、株高7个农艺性状的变异系数超过10%,是影响春小麦特征特性的主要农艺性状;参试材料分为3类,第Ⅱ类材料的综合表现较优,该组材料的生物产量、单株产量较大,千粒重、穗粒数适中,是综合性状表现较为理想的育种选择材料。

Abstract: In order to make efficient use of spring wheat germplasm resources and provide material for wheat cultivars breeding, 9 agronomic traits of 30 testing materials were tested for principal component analysis and cluster analysis. The results showed that 7 agronomic traits of effective number of tillers, biological yield, grain yield per plant, grain number per spike, spike length, thousand-grain weight and plant height have a high coefficient of variation over 10% , and they were the main agronomic traits that had an effect on the characteristics of spring wheat. Material could be divided into 3 categories, and the materials in the second category had excellent synthetic performance, the biological yield and grain yield per plant were large, thousand-grain weight and grain number per spike were moderate, so they were good breeding materials with ideal comprehensive characters.
