摘　　要：粳恢35是用"人工制恢"法选育的能恢复野败型粳稻不育系的粳型新恢复系,与野败型粳稻三系不育系热粳1A配组育成具有米质优、中抗稻瘟病、花粉量大等特点,于2012年通过重庆市品种审定委员会技术鉴定。杂交粳稻组合热粳优35(热粳1A/粳恢35),在区试中表现高产、抗病、米质优,于2014年2月通过重庆市农作物品种审定委员会审定。Developed by way of cross breeding,Jinghui 35 is a new japonica-type restorer line in rice with the restoring ability to the WA-type japonica CMS line. It shows fine grain quality,moderate blast resistance and heavy pollen load. In 2012,it was technically identified in Chongqing. Crossing it to Rejing 1A,a WA-type japonica CMS line,the japonica hybrid combination Rejingyou 35（ Rejing 1A / Jinghui 35） was successfully developed and performed well in regional trials with high yield,blast resistance and good grain quality. Rejingyou 35 was registered for release to commercial production by Chongqing Crop Variety Appraisal Committee in February,2014.
