摘　　要： 本文通过对101个冬性、半冬性的甘蓝型油菜材料在湛江引种试验，以及2个年度的品种比较试验材料进行生态适应性分析研究，结果表明：冬性、半冬性甘蓝型油菜，在湛江也有正常的物候期和生长发育期，农艺性状表现良好，参试品种均能正常开花结籽，2006—2007年度的产量为1238—1944kg／hm^2，2007-2008年度的产量为1350—1951kg,／hm^2然而，湛江冬季气温帮达不到阶段发育学说认为冬性、半冬性甘蓝型油菜所需要通过春化阶段的低温，这表明了冬性、半冬性的甘蓝型油莱品种通过春化阶段也可以不需要严格的低温，因此，华南的生态气候条件可以种植甘蓝型油菜。 Based on the introduction testing of 101 materials in rapeseed （Brassica napus L. ） ,two annual variety comparison tests of 17 materials were analyzed to study ecological adaptation of rapeseed in Zhanjiang. The results showed that planted rapeseed in Zhanjiang had also normal the phenophase, growth-development stage and period, the performance of good agronomic traits, flowered and setted normally. In the experiments of 2006 - 2007 and 2007 - 2008, the yield were 1238 - 1944 and 1350 - 1951 kg/hm2 separately, but the winter＇ s temperature in Zhanjiang was above the temperature that rapeseed need in stage of vernalization by the theory of phasic development. This showed that the winter, semi-winter varieties of rapeseed through the vernalization stage need not a strict low-temperature. Therefore, the eco-climatic conditions in South China could be appropriate to planting the Brassica napus L.
