摘　　要：T优15是以优质不育系T98A为母本,与自选的新恢复系R15测配选育而成的三系杂交早稻新组合,该组合综合性状优良,高产稳产,2006—2007年参加国家南方稻区早稻区试,平均单产7.5 t/hm2,比对照浙733增产4.32%,抗逆能力强,生育期适宜,适应性广,制种易获高产,2007年11月通过国家农作物品种审定委员会审定(国审稻2007005号)。介绍了T优15的选育过程、主要特征特性、栽培技术及高产制种技术要点。T You 15, derived from T98A, a fine quality CMS line, and R15, a new restorer line, is a new three- line early hybrid rice combination developed by the Hunan Huaihua Aopulong Crop Breeding Engineering Institute. It has a good integrated characteristic and a high and stable yield. In 2006 and 2007, it yielded averagely 7.3 t/hm^2, 4.32% higher than the check hybrid Zhe 733 in the National Early Rice Regional Trials of the South Rice Growing Area. It showed a strong stress resistance, suitable early maturity, wide adaptability and easiness in hybrid seed production. It was certified and released by the State Crop Variety Appraisal Committee in November, 2007. The breeding procedure, major characteristics and the key techniques of cultivation and hybrid seed production of T You 15 were introduced in this paper.
