Abstract: Correlation and path analysis establish the extent of association between yield and its components and also bring out the relative importance of their direct and indirect effects and thus, give a clear understanding of their association with seed yield. The experimental materials consisted of 30 diverse germplasm lines for character association ship study among characters revealed that seed yield per plant was positively and significantly correlated with number of umbel per plant, weight of grains per umbel, plant height and 1000 seed weight. Path coefficient analysis revealed that weight of grains per umbel, number of umbels per plant, plant height, days to maturity and 1000 seed weight had maximum positive direct effect on seed yield per plant. Consequently, simultaneous improvement of these traits by selection will improve seed yield of ajwain.
