The present investigation was carried out to study genetic parameters and performance of thirty four and forty eight genotypes of garden pea in kharif and rabi season, respectively, during 2017. Genotypes were grown in RBD design with two replications at Main Agricultural Research Station, UAS, Dharwad. Analysis of variance revealed significant differences among the genotypes, for all the characters studied, indicating the presence of considerable amount of variability in the material. During kharif season, the genotypes viz., DWDP-0007, DWDP-0023, Arkel, AP-3 and IIPR 45-UB-40 recorded high mean performance for pod yield per plant, pod length and number of seeds per pod. During rabi season, the genotypes viz., Jhunjhunu Matar, DWDP-0003, IIPR 45-UB30, Kashi Agethi and VRP-5 recorded high mean performance for pod yield per plant, pod length, number of seeds per pod and weight of 100 fresh seeds. Hence, these genotypes could be utilized in the hybridization programmes to bring pod yield improvement in garden pea. The estimates of genetic parameters revealed that GCV and PCV were high for days to first flowering, plant height, days to 50 % flowering (during both seasons), pod yield (during kharif), weight of hundred fresh and dry seeds (during rabi), indicating presence of high variability and less influence of environment on their expression. High heritability (broad sense) coupled with high genetic advance as per cent of mean was observed for plant height, days to first flowering, days to 50 % flowering, number of branches per plant (during both seasons), pod yield (during kharif), pod length, weight of hundred fresh and dry seeds (during rabi), indicating that simple selection would be helpful for the improvement of these characters as these are governed by additive gene action. Number of pods per plant, number of seeds per pod (during kharif), number of seeds per pod and protein content (during rabi) showed moderate heritability and genetic advance.
