中文摘要：
以实验室自育的5个油菜品种（系）及其他6份油菜品种（系）为试验材料,研究了这11份油菜品种（系）在轻（中）度盐化土中的越冬性状、生物学特性、产量构成特性,得出如下结论：南盐油系列品系（种）在盐土上植株生长势强,从基部开始分枝,分枝多;南盐油系列品种（系）茎粗与宁油16、三北98、秦油66和秦油9号差异不明显,但高于宝杂油1号和秦油33;各品种（系）株高差异不大;荚长与荚宽差异也不大。南盐油系列品系（种）产量显著高于对比的宝杂油1号、秦油66、秦油9和秦油33,一次与二次分枝数与菜籽产量的回归分析显示其R2均达极显著水平。
英文摘要：
In order to screen suitable rapeseed varieties with high yield and quality in saline soil of coastal beach and to provide a reliable theoretical basis for more efficient use of the coastal beach resources,the characteristics of winter traits,biological and yield component characteristics of 11 Brassica napus L.varieties including five varieties breeded by key laboratory of marine biology,Jiangsu Province（NY） and other six varieties were studied in northern-coastal middle-degree saline mudflat of Jiangsu province in 2009.The results were as follows：The growth of NY cultivars was better than other 6 varieties in the saline soil.The branches of NY cultivars were grown from the base of the main stem.There were more branches in NY cultivars than other 6 varieties.There was no significant difference in main stem diameter among the NY cultivars,Ningyou 16,Sanbei98,Qinyou 66 and Qinyou 9;while the main stem diameter of NY cultivars was higher than Baozayou 1 and Qinyou 33.There was little difference in plant height,pod length and pod width for all varieties,the yields of NY cultivars were significantly higher than Baozayou 1,Qinyou 66,Qinyou 9 and Qinyou 33.The correlation were significant between the first and the second numbers of branches and oilseed yields.
