摘　　要：H344S是以1892S为母本、以广占63S为父本杂交,经过7年12代系谱选择育成的育性稳定、败育彻底、育性转换临界温度较低(23.5℃)、株叶形态好、穗大粒多、抗性较好、米质优、配合力高、异交结实率高的籼型光温敏核不育系,2012年通过安徽省品种审定委员会技术鉴定。Derived from the cross of 1892 S and Guangzhan 63 S,H344S is a new PTGMS line in indica rice. It shows the characteristics of complete and stable male sterility with 100% of sterile plants and pollen sterility,lowcritical temperature（ 23. 5℃）,good plant type,big panicles with many spikelets,good blast resistance,good grain quality,high combining ability and favorable outcrossing habits. It was approved for commercialization by Anhui Provincial Crop Variety Release Committee in 2012.
