依据红麻高产育种目标,利用因子分析和聚类分析对40个红麻品种(系)的9个表型性状进行分析。结果表明:供试材料9个表型性状的变异系数为5.13%~25.33%,具有较大差异和丰富的遗传多样性;对供试红麻材料进行聚类分析,可分为3大类,其中,第Ⅲ类群属理想的高产品系。二维排序分析,评选出7个综合性状表现较好的亲本,T17-2、福红951、FH航992、H1301、ZHKX-01、福航优1号、福航优3号共7个品系,可在生产和育种中加以利用。
According to the goal of kenaf high yield breeding, 9 phenotypic traits of 40 kenaf varieties (lines) were analyzed by factor analysis and cluster analysis. The results showed that the coefficient of variation of the 9 phenotypic traits was 5.13% ~ 25.33%, which had great difference and rich genetic diversity. Cluster analysis of kenaf materials could be divided into three categories, Among them, the third group is an ideal high-product line. Two-dimensional sequencing analysis, seven parents with better comprehensive traits were selected, including 7 T17-2, Fuhong 951, FH Hang 992, H1301, ZHKX-01, Fuhangyou 1 and Fuhangyou 3 , Can be used in production and breeding.
