摘 要:应用1979-2007年28个年度江苏省油菜品种区域试验汇总资料,对参试品种产量进行了分析,结果表明:区试参试品种及对照种单产比江苏省油菜单产高,但随着江苏省油菜生产水平不断提高,区试参试品种及对照种单产与江苏省油菜单产之间的差距呈下降趋势。区试参试品种单产后10年比前10年增加了10.53%,增加显著,对照单产年度间变化不大。参试品种间单产水平差距在逐渐减小,参试品种与对照种单产差距也在逐渐减小。参加区试的杂交组合年平均单产较常规品种高,1995-2007年12年来杂交组合比常规品种单产平均增加8.91%,增产显著。The yields of the regional tested rapeseed varieties were analyzed based on the data from 1979 to 2007 in Jiangsu Province. Both tested varieties and CK had higher yields per unit than rapeseed planted in Jinagsu Province. Howev- er,the difference in the yield per unit between tested varieties and CK and rapeseed planted in Jiangsu Province seemed to shrink with the improvement of planting level of rapeseed. The yield of tested varieties in the later ten years were increased by 10.53% (P 〈 0. 05 ) compared to that in the first ten years,while no obvious changes in yield of CK were observed. The differences in yield among tested varieties were narrowed, as well as that between tested varieties and CK. The avegrage yield of cross combinations was higher than that of conventional rapeseed varieties, with the average increased rate of 8. 91% in twelve years from 1995 to 2007.
