高油酸油菜与双低油菜的比较研究

摘要

采用4个高油酸品系（油酸含量在80％以上）与2个双低油菜品种，在田间试验条件下进行了小区比较研究。结果表明，高油酸油菜品种的农艺性状、种子产量以及抗病性等与双低油菜品种差异较小；在高油酸品种中以高油酸1号与高油酸2号表现最好，产量分别为2748.0 kg/hm2和2629.5 kg/hm2，种子含油量分别为46.2％和47.1％，全生育期为210 d左右，菌核病危害程度也较轻。硏究表明，优质高油酸油菜品种完全可在生产上推广应用。%A plot experiment was conducted in field with 4 high oleic acid rapeseed varieties and 2 double low rapeseed va-rieties as materials.The results were showed that there were little differences in agronomic traits ,seed yield and disease re-sistance between high oleic acid rapeseed varieties and double low rapeseed varieties.In high oleic acid rapeseed varieties , No.1 and No.2 variety performed best,the unit yield was 2 748.0 kg/hm2 and 2 629.5 kg/hm2,and the oil content in seed was 46.2%and 47.1%,respectively.Their whole duration was about 210 days,and the harmness of sclerotinia rot was lighter.The results showed that the rapeseed varieties with high oleic acid can be applied in production .
