摘要
[目的]筛选适合在盐渍化土壤上种植的优质、高产、耐盐油菜品种（系）。[方法]2013～2014年在江苏沿海滩涂上进行油菜品种比较试验，研究了6个油菜品种（系）在中度盐渍化土壤环境下的越冬性状、生物学性状、产量构成与离子含量等。[结果]苏新油系列品种（系）在盐渍化土壤上长势强、分枝多，产量显著高于其他3个供试品种；苏新油141和苏新油703根、茎和叶中K ＋含量显著高于其他供试品种（系），苏新油141根、茎和叶中的Na ＋和Cl －含量均高于其他供试品种（系）。[结论]苏新油系列品种（系）耐盐性强，适合在盐渍化土壤上生长，尤其是苏新油141。
Abstract
Objective] The aim was to screen out high quality, high yield and salt tolerant rape varieties(lines) which are suitable for culti-vating in saline soil.[Method] Comparison test of rape variety was conducted on Jiangsu coastal beach during 2013-2014, the overwintering traits, biological characters, yield components and ion content of 6 rape varieties( lines) under moderate saline soil environment.[ Result] Suxinyou series varieties ( lines) had strong growth potential and more branches in saline soil , yield was significantly higher than that of other test varieties; K +content in root, stem and leaf of Suxinyou 141 and Suxinyou 703 were significantly higher than that of other test varieties;Na +and Cl -content in root, stem and leaf of Suxinyou 141 were significantly higher than that of other test varieties.[ Conclusion] Suxinyou series varieties ( lines) are salt tolerant, which is suitable for growth in saline soil, especially for Suxinyou 141.
