Salinity tolerance of three mustard/rapeseed cuitivars

A pot experiment was carried out at the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, to evaluate salinity tolerance of mustard/rapeseed cultivars viz., BINAsarisha-5, BINAsarisha-6 and Safal during October 2003 to January 2004. Salinity levels were 4, 6, 8 and 10 dSrnwith a control (0.43 dSm ). Plant height, leaf area, total dry matter, number of siliqua per plant, number of seeds per siliqua, 1000-seed weight and harvest index were decreased with the increase of salinity compared to control. Na + content in leaves increased but K+content decreased with the increase orsalinity. BINAsarisha-6 showed the highest number of siliqua, seed yield per plant, harvest index, higher Na + and medium K+ content in leaves and BINAsarisha-5 showed the highest number of seeds per siliqua, 1000-seed weight, lower Na + and higher K+ content in leaves under the salinity levels. On the other hand, Safal showed the lowest number of seeds per siliqua, seed yield, higher Na + and the lowest K+ content in leaves. BINAsarisha-6 and B1NAsarisha-5 were found to be tolerant and Safal was less tolerant to imposed salinity.
