Twenty nine cross populations developed according to line × tester mating design along with their twelve parents raised from true potato seeds, were used to study variability and correlation for seven characters. The range of variation for all the characters were found to be wide and pronounced which indicated that characters were quantitative in nature and were under polygenic control. For all the characters, greater portion of the total δ2p was mostly contributed by the δ2g. Among the seven characters, tuber weight per plant showed the highest δ2g, PCV, GCV, H2b, GA and expected GA%. On the other hand, dry matter contents (%) showed the lowest H2b. Phenotypic and genotypic correlation coefficients of plant height with no. of tubers per plant and tuber weight per plant; no. of branches per plant with no. of tubers per plant and tuber weight per plant were found to be significant and positive.
