摘　　要：永兴A是福建省农业科学院水稻研究所以龙特甫B/金23B的杂交后代F8代中间材料作母本,以优质、抗稻瘟病保持系元丰B为父本进行杂交,在F4代用元丰A测交选育保持系,经过连续多代择优回交选育而成的野败型水稻三系不育系,具有不育性稳定、花粉败育彻底、株型松紧适中、柱头外露好、异交结实率高、分蘖力强、配合力好、米质优等特点,2021年通过福建省农作物品种审定。所配组合永兴优香粘(永兴A/九香粘)于2022年通过福建省农作物品种审定,米质达部颁一等优质食用稻品种品质标准。A wild abortive indica three-line male sterile line Yongxing A was derived from the cross between a stable progeny from Longtefu B(high outcrossing rate maintainer line)/Jin23B and Yuanfeng B(A fine quality and disease-resistant maintainer line)and then testcross of its F4 generation to Yuanfeng A,was a CMS line developed through successive backcrossing by the Rice Research Institute of Fujian Academy of Agricultural Sciences.This sterile line was characterized by stable fertility,moderate plant type,high stigma exsertion rate and outcrossing seed setting rate,strong tillering ability,good combining ability and high grain quality.It was registered and released by the Crop Cultivar Registration Committee of Fujian Province in 2020.Yongxingyouxiangzhan(Yongxing A/Jiuxiangzhan)was registered and released by the Crop Cultivar Registration Committee of Fujian Province in 2022 and the rice quality reached the quality standard of first-class high-quality edible rice varieties issued by the Ministry.
