摘　　要：6022S系安徽省农业科学院水稻研究所以1892S为母本,与6M022(3M178/9311 F_(6))杂交、自交,经5年7代选择育成的籼型光温敏核不育系。该不育系株型紧凑,分蘖力强,抗倒伏性好,不育起点温度低,异交结实率高,配合力强。2019年8月通过安徽省农作物品种审定委员会的鉴定。6022S所配组合表现出熟期适中,株高较矮,粒型较好,抗倒伏,高产优质等特点。6022S,derived from the cross of 1892S and 6M022(the 6th generation from a cross of 3M178 and 9311)followed by self-crossing,is a new Indica photo-and thermo-sensitive genic male sterile(PTGMS)line in rice,which is developed by the Rice Research Institute of Anhui Academy of Agricultural Sciences.It has the characteristics of good plant type,strong tillering ability,good resistance to lodging,low critical temperature of fertility alteration,high outcrossing rate and high combining ability.It was registered in Anhui Province in 2019,and its F1 hybrids showed the characteristics of moderate growth duration,short plant height,good grain shape,lodging resistance,high yield,good quality and so on.
