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。
The information of the original parents and their offspring of more than 1000 sugarcane lines and the genetic relationship of more than 100 self-breeding varieties were analyzed by using the variety resource information management system. Bred into China’s existing main hybrid lines of sugar cane only about 30 original parents. The original parents of the current cane varieties are bred, of which 10 are tropical species, and the utilization of wild species and sugar cane related plants is still very limited. There are at least seven common ancestors in existing sugarcane varieties, which are closely related.
