摘　　要：谷优2173是用强恢复系福恢2173与三系不育系谷丰A配组而成的三系中籼杂交水稻新组合。该组合具有群体整齐、熟期转色好、产量高、稳产性好、制种产量高等特点。2011年通过福建省农作物品种审定委员会区域性(三明)审定。福恢2173是2003年春季在海南用蜀恢527做母本,与A227杂交,2003年秋季在福州用其F1做母本与HK01(航86/台农67//多系1号)杂交,F3(HR328)、F4(ER435)代在上杭茶地自然稻瘟病区筛选,对所获得的优良单株连续多年在沙县和海南反复加代定向培育而成。介绍了该组合的选育过程、特征特性和制种技术要点。Guyou 2173 was developed by crossing the high quality 3-line male sterile Gufeng A with the restorer line,Fuhui 2173.The hybrid rice exhibited the desirable characteristics including population uniformity,good color change during mycelium ripening,high yield,stable yield,ecological adaptabilities and high seed production.It has been certified by Fujian Crop Variety Evaluation Committee（Sanming） in 2011.Fuhui 2173 was a result of crossing Shuhui 527 as the female parent with A227 in Hainan in the spring of 2003.The F1 derived from the combination was applied as the female parent to cross with HK01 in Fuzhou in the fall of this year.And then,its F3（HR328） and F4（ER435） were planted in the rice-blast-infected field at Shanghang for cultivars-screening.The selected plant lines were repeatedly cultivated for several generations in Shaxian and Hainan to assure cultivar stability.This paper presents the breeding procedures,hybrid characteristics and seed production of Guyou 2173.
