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重要的现实意义。利用低盐[EC1:5(1.08±0.09)m S/cm]和中盐[EC1:5(2.21±0.50)m S/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’4个品种具有较强的耐盐性,在EC1:51 m S/cm的滩涂上可获得2250 kg/hm2的产量,而在EC1:52 m S/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EC1:52.36 m S/cm的滩涂也可正常生长,可用于甘蓝型油菜的耐盐性改良。
In order to select salt-tolerant Brassica napus varieties, development and utilization of tidal field forrapeseed 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) m S/cm] and medium [EC1:5(2.21 ± 0.50) m S/cm] salinity tidal fields. The preliminary resultsindicated that,‘Fengyou 737',‘Huayouza 95',‘Naiyan 1'and‘Yanyouza 3'had salt tolerant and harvested2250 kg/hm^2 in tidal field with salinity of 1 m S/cm, and almost failed in the tidal field with 2 m S/cm salinity.Wild mustard materials selected from the coastal beach exhibited stronger salt tolerance, grow normally on EC1:52.36 m S/cm beach, can be used for improving the salt tolerance of Brassica napus.
