摘 要：
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。

摘 要：
Aimed at providing knowledge on exotic sugarcane germplasm for cross breeding and further utilization,22 qualitative traits and 7quantitative traits of 104 exotic sugarcane germplasm were analyzed to study phenotypic diversity. The result showed that the genetic diversity was rich in the internode color exposed,bud shape,hair group 57,pithy stems,the internode color unexposed,underlapping auricle,deciduous. The genetic variations of quantitative traits were mainly contributed by the stalk and tillers; Cluster analysis showed that 104 sugarcane germplasm could be divided into 3 groups,5 subgroups and 8 small groups.
