摘要
贡887S是以1892S作母本、育种中间材料8-8S/R9311作父本杂交,后连续多年单系单株加代和定向选育而成的优质两系中籼不育系.该不育系起点温度低,株叶型好,异交结实率高,稻米品质优良,所配杂交稻组合耐热性好.所配组合贡两优粤农丝苗、贡两优京贵占于2021年分别通过国家和江西省农作物品种审定委员会审定.
Abstract
Gong 887S,derived from the cross between 1892S and the breeding material of 8-8S/R9311,is a high-quality medium indica rice photo-thermo-sensitive genic male sterile(PTGMS)line developed through pedigree selection for many years.It has the advantages of low critical sterility-inducing temperature,good plant type,high outcrossing rate,excellent grain quality and strong heat tolerance in its F1 hybrids.The hybrid combinations derived from Gong 887S,Gongliangyou Yuenongsimiao and Gongliangyou Jingguizhan,were registered and released to commercial production by the National and Jiangxi Provincial Crop Variety Appraisal Committee in 2021,respectively.
