摘要
湖南杂交水稻研究中心利用株高矮、分蘖力强、抗倒性强的两系不育系深08S与抗病性好、米质优的两系不育系中间材料15S(Y58S/成恢993)杂交,选育出了株型理想、分蘖力和抗倒性强、配合力好、米质优、抗性较好的温敏核不育系炜567S,于2023年12月29日通过湖南省农作物品种审定委员会鉴定.利用该不育系配组育成的杂交中稻新组合炜两优2133于2024年通过湖南省农作物品种审定委员会审定.
Abstract
Wei 567S,derived from the cross between Shen 08S,a two-line sterile line with short plants,strong tillering ability and strong lodging resistance,and 15S(Y58S/Chenghui 993),a breeding material of two-line sterile line with fine grain quality and strong disease resistance,is a thermo-sensitive genic male sterile(TGMS)line in rice developed by Hunan Hybrid Rice Research Center.This sterile line has the characteristics of ideotype,strong tillering ability and lodging resistance,high combining ability,fine grain quality and good resistance.It was technically identified by Hunan Crop Variety Appraisal Committee in 2023.Weiliangyou 2133,a new medium hybrid rice combination derived from Wei 567S,was registered and released for commercial production by Hunan Crop Variety Appraisal Committee in 2024.
