摘　　要：豫油4号是利用细胞质雄性不育技术育成的甘蓝型双低油菜“三系”杂交种，突出表现为高产、优质、早熟、抗病等。在1993～1995年河南省油菜区试中，三年综评居第一位，平均单产2593．5kg／hm2，比同类型（双低）对照豫油2号增产26．7％，1994～1995年河南省生产试验中比秦油2号增产10．8％。抗病毒病，耐菌核病，早熟性好，全生育期231d。芥酸含量为0．241％，硫甙含量21．31μmol／g，含油量高达41．21％。Yuyou No. 4 (CMS 384A×CP015) was a new three line hybrid which bred with cytoplasmic male sterile. Yuyou No. 4 was vigorous in heterosis, high yield, high quality , early maturing,resistant to TMS, tolerance to Scleroinia scleroliorum. 0. 241 % of erucic acid in its oil, 41. 21 % of oil content, 21. 31μmol/g of glucosinolate content in its meal. The growth duration was 231d. The hybrid was tested in Henan provincial district test in 1993~1995. The average yield was 2593. 5kg/hm2.It was 26. 7% higher than the double low check variety Yuyou No. 2 (CK1 ). It was tested in Henan provinicial productive demanstration in 1994~1995. The average yield was 10. 8% higher than check hybrid Qinyou No. 2 (CK2).
