VARIETAL DIFFERENCES IN CANOLA (BRASSICA NAPUS L.) FOR THE GROWTH, YEILD AND YEILD COMPONENTS EXPOSED TO CADMIUM STRESS

Cadmium is highly toxic metallic pollutant which adversely affects the plant growth. A green house experiment was conducted to study the variation in growth, yield and yield component of canola (Brassica napus L.) varieties namely Waster, Abasin-95, Rainbow and Shiralee at the three plant growth stages, treated with 0, 6, 9 and 12 mg Cd kg(-1) soil. Maximum significant decrease in the growth parameters was observed with 12 mg Cd kg(-1) soil in all the varieties at all the sampling times. Among varieties Rainbow proved tolerant and showed minimum reduction in the attributes, whereas Shiralee emerged as sensitive and suffered maximum reduction.
