【摘要】 以广占63S为母本,与含苯达松敏感基因的农林8号M系为父本杂交后,择优回交一次,育成含苯达松敏感基因籼型光温敏核不育系绿敏S。该不育系表型与广占63相似,但对苯达松敏感,故其种子纯度较易保证。此外,它还具有育性稳定、育性转换起点温度低、异交特性较好、在海南可繁性较好、配组优势强等特点;2007年8月通过安徽省科学技术鉴定。更多还原

【Abstract】 Derived from the cross of Guangzhan 63 S(an indica PTGMS line) //Guangzhan 63 S/Norin 8 M(with Bentazone sensitivity genes),Lüming S is a new indica-type photo-and/or thermo-sensitive genic male sterile(PTGMS) line with Bentazone sensitivity genes in rice.It is similar to Guangzhan 63 S in phenotype,but it is sensitive to Bentazone,which is favorable to ensuring the hybrid seed purity.Moreover,it is characteristic of complete and stable male sterility,low critical sterility-inducing temperature,high outcrossing rate,easy multiplication in Hainan and good combining ability.It was technically identified in Anhui Province in August,2007.更多还原
