为提高国外引进甘蔗种质的利用效率,为甘蔗种质的杂交和种质创新利用提供参考。以104份国外引进甘蔗种质为材料,分析其22个质量性状和7个数量性状,研究其种间的表型多样性。结果表明,104份国外甘蔗种质的质量性状在曝光后节间颜色、芽形、57号毛群、蒲心、曝光前节间颜色、内叶耳和脱叶性的多样性十分丰富;数量性状中有效茎和分蘖的遗传变异较大;聚类结果把104份种质分为3个大类群、5个亚类群及8个小类群。
In order to improve the utilization efficiency of foreign introduced sugarcane germplasm and provide reference for sugarcane germplasm hybridization and germplasm utilization innovation. Using 104 foreign introduced sugarcane germplasms as materials, 22 quality traits and 7 quantitative traits were analyzed to study the phenotypic diversity of their species. The results showed that the quality traits of 104 foreign sugarcane germplasms were very rich after internode color, bud shape, 57th hair group, Poxin, internode color before exposure, inner ear and defoliation. The quantity The genetic variation of effective stems and tillers was larger in the traits. The results of cluster analysis divided 104 germplasms into three major groups, five sub-groups and eight minor groups.
