摘要:
2003年春季在海南用明恢86作母本与蜀恢527杂交,2003年晚季在福州用该杂交组合F1作母本,与多系1号杂交,后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,选育出恢复系福恢656。利用恢复系福恢656与三系不育系泰丰A配组,选育出三系晚籼杂交水稻新品种泰丰优656。该品种具有米质优,熟期转色好,丰产性好,制种产量高等特点,2013年通过福建省品种审定委员会审定。
Abstract:
Initially,a hybrid rice was bred by crossing Minghui 86 as the female parent with Shuhui 527 from Hainan.The cross combination was used as the female parent to breed with Duoxi 1from Fuzhou during late spring in 2003.And,the progeny were planted in a rice-blast-infected field at Shanghang for cultivar-screening.The finally selected plant lines were named Fuhui 656 and subjected to repeat cultivations for several generations in Shaxian and Hainan to assure cultivar stability.Subsequently,this restorer line,Fuhui 656 was bred with 3-line male sterile Taifeng A to result in Taifengyou 656.The new hybrid rice exhibited many desirable characteristics including high grain quality,yield and seed production,as well as good color change during ripening.It has been certified by Fujian Crop Variety Evaluation Committees in 2013.
