摘　　要：概述了感温型早熟组合在广西水稻生产中的地位及应用概况,针对广西感温型早熟组合选育存在的产量低、米质差、组合类型单一、缺乏抗病组合等问题,提出扩大品种资源的引进、加强感温型优质早熟不育系与恢复系的选育、开展穿梭育种、重视耐寒早熟组合的选育与筛选等策略,以促进广西感温型早熟组合的选育与推广应用。This paper discussed the importance,application and the current status of thermo-sensitive early maturing rice hybrids for Guangxi ＇ s rice production. It had a great development of breeding thermo-sensltive early maturing hybrids in Guangxi in recent years. But there are some problems,including not enough hyhrids released and weak resistance of this kind hybrids,imbalance of yield and grain quality. Based on the analysis,the some considerations of breeding thermo-sensitive early maturing rice hybrids in Guangxi, China have been advised in the paper.
