摘　　要：以甘蓝型油菜隐性核不育全不育系6515A与恢复系6373R为亲本组配育成了高效型杂交油菜新组合油07-4。该组合在2008—2010年贵州省油菜区域试验中,平均产量163.52kg/667m2,比对照(油研10号)增产17.08%,增产达极显著水平;生产试验平均产量165.53kg/667m2,较对照增产3.99%;平均产油量为74.76kg/667m2,比对照增产21.82%;平均生育期为214.2d,比对照早熟2.8d;含油量45.72%,芥酸0.1%,硫甙28.23μmol/g饼,种子蛋白质24.16%;抗倒性和抗寒性强,耐菌核病。于2010年12月通过贵州省农作物品种审定委员会审定并命名为油科1号。Youke 1,a new hybrid Brassica napus variety with 214.2d growth period,45.72% oil content,28.23μmol glucosinolate/g cake,0.1% erucic acid content,24.16% protein content,strong resistance to lodging and cold and tolerance to sclerotiniose bred from 6515A（a recessive nucleic male sterile line）×6373R（a restorer line） was approved by Guizhou Crops Variety Examination Committee in 2010.The average yield in Guizhou regional tests and production tests during 2008-2010 was 163.52 kg/667m2 and 165.53kg/667m2,17.08% and 3.99% higher than CK（Youyan 10） respectively.The average oil yield was 74.76kg/667m2,21.82% higher than CK.
