1. Increasing the levels of applied Cd or Pb significantly decreased the dry matter yield of shoots, roots and whole plants for both red radish and kenaf, under with or without addition of soil amendments, but the values under addition of soil amendments were still higher than that of without addition.2. The adverse effect of Cd or Pb on plant growth of red radish was much more pronounced in roots than in shoots, while the adverse effect of Cd or Pb on plant growth of kenaf plants was much more pronounced in shoots than in roots. However, the adverse effect of Cd or Pb on plant growth was much more pronounced in red radish than in kenaf plants.3. Application of soil amendments under Cd or Pb levels increased the dry matter yield of red radish and kenaf shoots, roots and whole plants as compared with no application. The highest increases were obtained with the application of compost, while the lowest increases were obtained with Zn-EDTA treatment. The efficiency of the added soil amendments in increasing red radish and kenaf yields of shoots, roots and whole plants could be arranged as follows: compost < gypsum < liming < Fe-EDDHA < Zn-EDTA.4. Increasing the levels of applied Cd up to 15 mg kg-1 soil and Pb up to 300 mg kg-1 soil significantly increased Cd or Pb content and uptake by shoots and roots for both two plants, under with or without addition of soil amendments, but the values of Cd or Pb content under addition of soil amendments were lower than that of without addition.General means of litter size and litter weight traits in NZW were higher than that in cal. CV% of litter size and PWM traits were higher in Cal than in NZW. Effect of parity order was significant in each of LSB, LS21, LW21, LWW, MBB, MB21, LG21, LG and MWP traits in NZW and in each of LWB, LWW, BBW, and LG traits in Cal. Effect of season of kindling was significant on each of LSW and LG traits in NZW and on each of LWW, LG21 and LG traits in Cal. Effect of year of kindling was significant on each of LSW, LWW, LG21 and LG traits in NZW.Heritability estimates ranged between 0.01 to 0.15 while the repeatability estimates were ranged from 0.07 to 0.27 for all traits studied in NZW and Cal rabbit breeds, respectively. Permanent environmental effect estimates ranged from 0.1 to 0.15 in both breeds studied.In general, estimates of heritability, repeatability, and permanent environmental effects were low or moderate in the two breeds studied.
