摘　　要：赣野A是江西省农科院水稻研究所将东乡野生稻的耐冷性和耐低氧萌发能力导入抗稻瘟病保持系赣香B后再与赣香A测交和回交育成的野败型三系籼稻不育系。该不育系败育彻底,异交结实率高,配合力较强,具有较强的耐冷性和耐低氧萌发能力,在直播杂交稻育种中应用前景广阔。2019年通过了江西省品种审定。Ganye A, derived from the cross between Dongxiang wild rice with strong low temperature tolerance and seed anoxia germinability and the maintainer line Ganxiang B with blast resistance and testcross to Ganxiang A followed by successive backcrosses, is a WA-type indica CMS line developed by the Rice Research Institute of Jiangxi Academy of Agricultural Sciences. It has complete male sterility, high stigma exsertion rate and outcrossing rate, good combining ability, strong low temperature tolerance and seed anoxia germinability, showing a broad prospect in breeding of directseeding hybrid rice. In 2019, it was registered by Jiangxi Crop Variety Appraisal Committee.
