摘要:

重庆市农业科学院以甘蓝型油菜细胞质雄性不育系重A10为母本,以恢复系重79R为父本,育成高产抗病油菜新品种重油2号。在2018—2019年度、2019—2020年度西南区冬油菜联合品比区域试验中,重油2号2 a的平均产量为2 861.80 kg·hm-2,比对照品种蓉油18增产5.07%。此外,重油2号的种子中未检出芥酸,硫代葡萄糖苷的检出含量为18.93 μmol·g-1,含油量43.8%。重油2号于2023年通过非主要农作物品种登记,适宜在重庆、四川、贵州及陕西等地区种植。本文对重油2号亲本选育过程、特征特性、多年多点试验结果、关键栽培技术等进行了总结,以期为其在生产上的推广与应用提供技术支撑。

Abstract:

Chongqing Academy of Agricultural Sciences developed a high-yield and disease resistant new rapeseed variety,Chongyou No.2,using cytoplasmic male sterile line ChongA10 as the female parent and restorer line Chong79R as the male parent in Brassica napus. In the regional joint variety comparative test of winter rapeseed in southwest China for two consecutive years in 2018—2019 and 2019—2020,the average yield of Chongyou No.2 was 2 861.80 kg·hm-2,which was 5.07% higher than the control variety Rongyou 18. The content of erucic acid in its seeds was not detected,and the content of glucosinolates was 18.93 μmol·g-1,with an oil content of 43.8%. Chongyou No.2 had been registered as a non-major crop variety in 2023 and was suitable for cultivation in Chongqing,Sichuan,Guizhou,and Shaanxi. This article summarized the breeding process,characteristics,years of multi-point experimental results,and key cultivation techniques of Chongyou No.2,so as to provide technical support for its better promotion and application in production.

Key words: high yield, disease resistance, rapeseed (Brassica napus), Chongyou No.2, breeding
