摘　　要：针对华南稻区杂交稻高产难优质、抗性不强的问题,通过创制高配合力优质亲本,育成了粒型细长、品质优、食味好的不育系丰田1A。截至2021年底,用丰田1A配组育成14个弱感光型优质杂交稻组合,其中13个组合品质达部标优质3级及以上标准,1个组合被认定为绿色超级稻,较好实现了杂交稻高产、优质、抗性的协调提升。丰田优1999是利用丰田1A与恢复系R1999配组育成的优质弱感光型杂交稻新组合,2019年通过广西农作物品种审定委员会审定,同年通过广东省引种备案,目前已成为弱感光型杂交稻的当家组合之一。In response to the problem of high yield but poor quality and weak resistance of hybrid rice in the South China,a cytoplasmic male sterile line Fengtian 1A with slender grain shape,fine quality and good taste was bred by creating fine quality parents with high combining ability.By the end of 2021,14 weak-photosensitive high-quality hybrid rice combinations have been bred using Fengtian 1A,13 combinations of which have meet the ministerial high-quality standard of grade 3 or above,and 1 combination has been recognized as green super rice,achieving a coordinated improvement in high yield,high quality,and resistance of hybrid rice.Fengtianyou 1999 is a new hybrid rice combination with high-quality and weak-photosensitivity derived from the male sterile line Fengtian 1A and the restorer line R1999.It was registered and released to commercial production by the Guangxi Crop Variety Appraisal Committee in 2019 and passed the introduction record of Guangdong Province in the same year.It has become the main combination of weak-photosensitive hybrid rice.
