摘要
为选育产量和含油量双高、抗逆性强和适应性广的双低油菜品种,以自育的细胞质雄性不育系‘汉3A’为母本,与自育的恢复系‘475R’进行杂交,经过筛选鉴定,获得了高油高产多抗的甘蓝型油菜新品种‘汉油23’。在2020—2022年度连续2 a的长江流域(上游、中游、下游)油菜新品种区域试验中,2 a试验平均产量为3167.8 kg/hm^(2),芥酸平均含量为0.105%,硫苷平均含量为17.48μmol/g,平均含油量为47.57%,能够抗菌核病和病毒病,抗寒性和抗倒性强。于2024年通过农业农村部登记,登记编号GPD油菜(2024)610234,该品种还具有高产优质、抗逆性强、适应性广、适宜机械化的特点。本研究介绍了该品种的选育过程、特征特性和高产栽培技术,为其推广应用提供理论依据和技术支撑。
To breed the double-low(low erucic acid and low glucosinolates)rapeseed variety with the double-high of yield and oil-content,strong stress tolerance and wide adaptability,we used cytoplasmic male line'Han 3A'as female parent to cross with the restorer line'475R',after selection and identification,we obtained a variety'Hanyou 23'with high oil content and high yield and multi resistance in Brassica napus L.Its average yield in comparative experiment of new rapeseed varieties in the Yangtze River Basin(the upper,middle and lower reaches)for two consecutive years(2020-2022)was 3167.8 kg/hm^(2),the erucic acid content was 0.105%,the glucosinolate content was 17.48μmol/g,and the oil content was 47.57%.This variety had resistance to sclerotinia sclerotiorum and viral diseases,strong cold resistance and good lodging resistance.The variety was registered by the Ministry of Agriculture and Rural Affairs in 2024 with the registration number GPD rape(2024)610234.‘Hanyou 23’was a hybrid Brassica napus variety with high yield and superior quality,strong stress tolerance,wide adaptability and suitability for agriculture mechanization.This paper provided the basis for its popularization and application by introducing the breeding process,characteristics and high-yield cultivation technology.
