绿豆种质资源农艺性状的因子分析及综合评价

为合理利用绿豆种质资源,本研究以55份绿豆种质资源为材料,通过对其10个农艺性状进行因子分析及聚类分析。结果表明:10个农艺性状的变异系数为8.57%~47.19%,其中单株粒重变异系数最大,生育期变异系数最小。将10个农艺性状简化为结荚数因子、高度因子、粒数因子、粒重因子和生育期因子5个独立的主因子,该5个主因子可以反映原始信息的86.340%。经综合得分排序,评选出10份性状优良的绿豆种质资源。聚类分析将55份种质资源的10个数量性状分为3大类,类群I、类群II、类群III分别包括22份、7份、26份材料。结合综合评价和聚类分析认为,在黑龙江绿豆生产中,‘安绿8号’、‘佳木斯黄绿豆’、‘冀绿1号’可作为品种选育的改良亲本,也可大面积种植利用。

Factor Analysis and Comprehensive Assessment of Agronomic Characters of Mungbean (Vigna radiata L.) Germplasm Resources

In order to provide theoretical basis for rational use of mungbean varieties, 10 agronomic traits of 55 mungbean germplasm resources were analyzed through factor analysis and cluster analysis in this study. The results showed that the variation coefficient of 10 agronomic traits was from 8.57% to 47.19%, among them the highest was seed weight per plant, and the lowest was growth period. Further study divided these traits into 5 main factors, namely podding number, plant height, seed number, seed weight and growth period which represented 86.340% information of total traits by factor analysis. 10 accessions of mungbean germplasm resources with excellent traits were selected based on comprehensive score. According to the results of cluster analysis, 10 quantity traits of 55 mungbean germplasm resources could be classified into three clusters. Cluster I, cluster II and cluster III included 22 accessions, 7 accessions, 26 accessions, respectively. Combined with the comprehensive evaluation and cluster analysis, in the mung bean production in heilongjiang province, ''Ann green 8'', ''Jiamusi yellow mung bean'', ''Jilv 1'' could be not only used as breeding materials, but also planted in large area.
