The individual regression analysis has been given in the previous com-munication. In this article the results obtained from joint regression analysis (Table 1) according to Perkins and Jinks (1968) for all the groups of characters except leaf potential and leaf area where conventional g x e interaction analysis was done, are being presented. The method and mater-ials and the layout of the experiment was the same as reported by Gupta et al. (1981). The groupwise results obtained are given below.
