高含油量甘蓝型油菜杂交新品种‘沪油杂7号'的选育

Breeding of a new high oil-content hybrid variety 'Huyouza 7' of Brassica napus

利用甘蓝型油菜高含油量隐性核不育纯合两型系20228AB、临保系M-6477、恢复系08184,经"三系"配套育成的高含油量双低油菜杂交新品种‘沪油杂7号',其籽粒含油率高达47.76%,芥酸含量为0,硫苷总量为21.75μmol/g。在2008-2009年度上海市油菜区域试验中,平均产量2 622.45 kg/hm^2,比对照‘沪油15'增产8.85%;产油量1 252.50 kg/hm^2,比对照增产17.29%。在2009-2010年度上海市油菜区域试验中,平均产量3 146.70 kg/hm^2,比对照‘沪油杂4号'增产14.48%;产油量1 346.10 kg/hm^2,比对照增产12.46%。

‘Huyouza 7’,a new high oil-content and double-low hybrid variety of Brassica napus, was bred by matching of three lines-a high oil-content recessive genic male sterile homozygous two- type line 20228AB,a temporary maintenance line M-6477 and a restoring line 08184. Its seeds5oil con-tent was up to 47.76% ,the erucic acid content of oil was 0.00% and the glucosinolate content of meal was 21.75 mol/g. Its average seed and oil yields were 2622.45 kg/hm^2 and 1252.50 kg/hm^2 ,increasing by 8.85% and 17.29% respectively over those of the control variety ＇Huyou 15＇in Shanghai regional rapeseed test of 2008 - 2009. And in Shanghai regional rapeseed test of 2009 - 2010 its average seed and oil yields were 3146.70 kg/hm^2 and 1346.10 kg/hm^2 ,increasing by 14.48% and 12.46% respectively over those of the control variety ＇Huyouza 4＇.
