摘要
利用品种资源信息管理系统对1000多个甘蔗品系的原始亲本及其育成后代的信息，以及100多个自育品种的血缘关系进行了分析。育成我国现有甘蔗主要杂交品系的原始亲本仅30个左右。育成目前甘蔗品种的原始亲本为用个，其中10个为热带种品系，野生种及甘蔗近缘植物的利用仍非常有限。现有甘蔗品种至少有7个共同的祖先，亲缘关系非常密切。
Thc ancestors of more than 1, 000 hybrid clones with their later gencrations and the pedigrees of 100 home-bred varieties were analysed by using the sugarcane germplasm data base management system. The results rcvealed that about 30clones of basic germplasm of sugarcane and wild trlatives were used for the development of the current hybrid clones, and 10 of the 18 clones of primitive parents of the 100 home-bred varieties belonged to S officinarum L., but wild sugarcane genetic resources and relative plants had been limitedly used so far.descending from at least 7 common primitive parents, the home-bred varieties were genetically associated closely with one another.
