Comparison of Rape Varieties(Lines) in Saline Soil

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.
