摘要： 筛选耐盐油菜品种，开发利用沿海滩涂发展油菜生产，在人多地少的江苏省具有摘要的现实意义。本研究利用低盐（EC1:51.08±0.09ms/cm）和中盐（EC1:52.21±0.50ms/cm）滩涂进行了8个油菜品种/系的产量和耐盐性鉴定，初步结果表明沣油737、华油杂95、耐盐1号、盐油杂3号等4个品种具有较强的耐盐性，在EC1:51ms/cm的滩涂上可获得150kg/亩的产量，而在EC1:52ms/cm的滩涂上则几乎失收。而来自于滩涂野生的芥菜材料则表现出极强的耐盐性，在EC1:52.36ms/cm的滩涂也可正常生长，可用于甘蓝型油菜的耐盐性改良。

Abstract: Selection of salt-tolerant Brassica napus varieties, development and utilization of tidal field for rapeseed production, has the practical significance in Jiangsu Province with more people and less land. Eight Brassica napus varieties/lines were utilized for yield and salt tolerance identification and screening in low (EC1:51.08±0.09 mS/cm) and medium (EC1:52.21±0.50 mS/cm) salinity tidal fields. The preliminary results indicated that, ‘Fengyou 737’, ‘Huayouza 95’, ‘Naiyan 1’ and ‘Yanyouza 3’ performance tolerant and harvested 2250 kg/hm2 in tidal field with salinity of 1 mS/cm, and almost lost in the tidal field with 2 mS/cm salinity. Wild mustard materials selected from the coastal beach exhibited stronger salt tolerance, grow normally on EC1:5 2.36 mS/cm beach, can be used for improving the salt tolerance of Brassica napus.
