A field investigation with fourteen ajwain genotypes was conducted at the College of Horticulture, Bengaluru, India, from October 2019 to April 2020. Eleven characters such as plant height, primary & secondary branches per plant, days to 50 per cent flowering, days to maturity, umbels per plant, Umbellet per umbel, seeds per umbel, test weight, harvest index and seed yield per plant were subjected to correlation and path analysis. Significant positive genotypic and phenotypic association of plant height, primary branches per plant, umbels per plant, umbellate per umbel, seeds per umbel and harvest index with seed yield per plant was exhibited by the crop. Likewise, significant negative correlation was noticed for yield with days taken for 50 per cent flowering and number of days for maturity. Path analysis revealed that primary branches, umbels per plant, Umbellet per umbel, seeds per umbel, test weight and harvest index exhibited positive and direct effects on seed yield per plant whereas secondary branches per plant and days to maturity registered negative direct effect on seed yield per plant. From the analysis it is evident that, these traits should be selected for further crop improvement.
