Abstract
The field experiment was carried out during Rabi season of the year 2019-20 at the Department of Seed Technology Farm, Sardarkrushinagar Dantiwada Agricultural University, S K Nagar, Dantiwada, Gujarat. The study was undertaken on 40 genotypes of Fennel (Foeniculum vulgare Miller) using Randomized Block Design with three replications. This study revealed that seed yield per plant found to be positively and significantly correlated with number of umbels per plant, number of umbellates per main umbel, seeds per umbel and 1000-seed weight. These yield contributing characters also possessed highly significant and positive correlation among themselves. Seed yield per plant also have positive correlation with plant height at genotypic level. Path coefficient analysis indicated that the highest positive direct effect of number of umbels per plant followed by days to flowering, number of umbellates per main umbel, 1000-seed weight, seed oil content and plant height. Days to maturity, number of branches per plant and seeds per umbel had negative direct effect. The highest indirect effect was via days to maturity, number of branches per plant and seeds per umbel. The genetic correlation of number of umbels per plant, number of umbellates per main umbel, seeds per umbel and 1000-seed weight were also positive and highly significant with seed yield per plant.
