摘　　要：目前,杂种优势利用是选育高产、优质油菜新品种的重要途径,自贡市农业科学研究院(以下简称“本院”)近些年通过改良油菜种质,利用杂种优势不断选育杂交油菜新品种,助力四川油菜产业发展。‘贡油5005’是本院以胞质不育系‘7149A’与双低恢复系‘7(50)R’杂交、鉴选出的首个高产、优质甘蓝型胞质不育杂交油菜新品种。在2017—2019年四川省机收油菜新品种试验中,2年试验平均产量为2654.1 kg/hm^(2),较对照‘德油6号’增产10.68%,芥酸平均含量为0.261%,商品菜籽硫甙平均含量为24.81μmol/g饼,平均含油量为43.32%,籽粒黑色。于2021年通过农业农村部登记,登记编号GPD油菜(2021)510021。该品种高产优质,是适宜于四川平坝、丘陵地区冬油菜区种植的双低甘蓝型胞质不育杂交油菜新品种,具有较高的推广应用价值。At present,heterosis utilization is an important way to breed new varieties of rapeseed with high yield and superior quality.Zigong Academy of Agricultural Sciences has continuously selected new varieties of rapeseed by improving rapeseed germplasm and using heterosis to help the development of rapeseed industry in Sichuan in recent years.‘Gongyou 5005’is the first hybrid Brassica napus variety with cytoplasmic male sterility accompanied by high yield and superior quality,which was selected by crossing cytoplasmic male sterility(CMS)line‘7149A’with double low restorer line‘7(50)R’.Its average yield in comparative experiment of new rapeseed varieties harvested by machine in Sichuan Province(2017-2019)was 2654.1 kg/hm^(2),increased by 10.68%compared with that of the control variety‘Deyou 6’;the average content of erucic acid,rapeseed glucosinolates,and oil of‘Gongyou 5005’was 0.261%,24.81μmol/g cake,and 43.32%,respectively,and the seeds were black.The variety was registered by the Ministry of Agriculture and Rural Affairs in 2021 with the registration number GPD rape(2021)510021.‘Gongyou 5005’is a hybrid Brassica napus variety of cytoplasmic male sterility with high yield and superior quality and is suitable for planting in winter rapeseed producing area in hilly and plain regions of Sichuan,and has a high value of popularization and application.
