高含油量油菜新品种‘沪油19’的选育和高产栽培技术研究

摘要

'Huyou 19',a new rape cultivar of Brassica napus with high oil content,was bred by means of multiple cross between varieties (lines) .being 0.1% in erucic acid content, 18. 87 /zmol/g in glucosinolate content and 49.16% in rapeseed oil content. In the Shanghai regional test of rape,it av-eragely yielded 2 589.75 kg/hm2 rapeseed and produced 1 273.12 kg/hm2 rapeseed oil, increasing by 14.78% over 'Huyou 15'; In the Shanghai production test of rape,it averagely yielded 3 020.85 kg/hm2 rapeseed and produced 1 485.05 kg/hm2 rapeseed oil,increasing by 21.92% over 'Huyou 15'.%‘沪油19'是通过品种(系)间复交的方法选育的高含油量甘蓝型双低油菜品种,其芥酸含量0.1％,硫苷含量18.87 μmol/g,种子含油量49.16％.在上海市油菜区域试验中,平均产量2 589.75 kg/hm2,产油量1 273.12 kg/hm2,较‘沪油15’增加14.78％；在上海市油菜生产试验中,平均产量3 020.85 kg/hm2,产油量1 485.05 kg/hm2,较‘沪油15’增加21.92％.
