In any selection programme the association of the yield contributing characters plays a major role for increase of the yield. Eleven intra hirsutum F4 populations were raised in winter rainfed condition in Cotton Research Station, Veppanthattai during the year 2017.Single plants were selected based on biometrical traits seed cotton yield (g/plat), plant height (cm), number of monopodial branches per plant, number of sympodial branches per plant, number of bolls per plant. Among the eleven crosses the two crosses viz., F 2617 x Surabhi and African I -2 x TCH 1705 -250 in which number of plants selected were higher is used to study the interrelationship The results revealed that the positive significant correlation for the plant height with seed cotton yield per plant and number of sympodial branches per plant. Path analysis revealed the highest positive direct effects for plant height and number of bolls per plant in both the crosses. The positive indirect effect for seed cotton yield was observed for number of bolls per plant. Hence selection based on the above traits will be useful in selection programme in rainfed conditions.
