In the present investigation, thirty-eight diverse genotypes were utilized to understand the correlation and path analysis among seed yield and related yield attributing characteristics in fennel. The experiment was conducted following a randomized complete block design at the College of Horticulture, Bagalkot, during the year 2020-21. Data pertaining to 17 agronomic and quality traits were recorded in three replicates and subjected to statistical analysis. A majority of the traits exhibited high correlation coefficients at both genotypic and phenotypic levels, indicating inherent associations among them. Parameters such as plant height, days to initial flowering, days to maturity, number of umbels per plant, number of seeds per umbellet, and harvest index displayed significant positive correlations with seed yield per plant at both phenotypic and genotypic levels. Conversely, traits like dry umbel weight, test weight and aphid incidence showed negative associations with most of the studied traits. Based on path analysis, the number of branches per plant, days to 50 per cent flowering, number of seeds per umbellet, and oil content exerted a higher positive direct effect on seed yield per plant, revealing the need to emphasize on these characters for the genetic enhancement of fennel to augment seed yield.
