本文报道了1997年及1998年海南甘蔗育种场甘蔗基础种质种性研究及其近年研究的综合评价。通过产量性状、糖分及抗病（黑穗病、嵌纹病）性诸方面的综评推荐一批优良原种种质作为基础杂交亲本。通过基础杂交、培育与选择，期望快速、有效获得用于经济杂交的新型种质与亲本，从而扩大甘蔗遗传育种基础，提高品种水平．
This paper reports on the research on the basic germplasm of sugarcane in Hainan sugarcane breeding farm in 1997 and 1998 and its comprehensive evaluation in recent years. Based on the comprehensive evaluation of yield traits, sugars and disease resistance (smut, mosaic disease), a batch of elite elite germplasm was selected as the basic hybrid parents. Through basic hybridization, breeding and selection, it is expected that the new germplasm and parents for economic crossbreeding will be rapidly and effectively obtained, thereby expanding the base of genetic and breeding sugarcane and increasing the variety level.
