摘　　要：经过8年的资源考察,收集到甘蔗亚族7个属14个种的资源植物700份;继而用近10年时间研究了它们的性状、锤度、花期、形态和分类地位,以及在云南境内海拔分布的上下限。在利用方面,主要开展了有性杂交育种研究,探索出在高原气候条件下诱导甘蔗开花的技术,获得一批含有新血缘的杂种后代。700 species of resourses of sugarcane,Saccuarinae belongs 7 genera, 14 species had been collected from Yunnan Province through investigation for 8 years.Then,the characteristics, Brix, flowering stage, morphological character, classification and distribution at the upper and lower limit of altitude were studied for 10 years. In the breeding study, the technique of inducing flowering under the plateau climate in this province had been researched and a number of intermediate hybrids bearing new kin had been obtained by sexualhybri-dization.
