Abstract

The experiment was conducted with 22 germplasm and laid out in randomized block design with three replications. The analysis of variance for 22 genotypes showed significant differences for all the traits, representing a broad spectrum of variability among the genotypes. High heritability coupled with high genetic advance as percentage of mean was recorded for No. of nodes at 60 days, No. of nodes at 40 days and No. of nodes at harvest, whereas, high heritability coupled with moderate genetic advance as percentage of mean was recorded for No. of seeds per pod, No. of nodes at 20 days, plant height (cm) at 20 days, No. primary branches at 20 days, root nodules at 60 days, days to 50 % flowering, No. of pods per plant, pod yield q/ha, pod length (cm), days to picking 1. significant and positive correlation was observed for pod yield (q/ha) with pod yield (g/plant), shelling %, chlorophyll content, days to maturity, days to picking 2, pod length (cm), days to 50 % flowering, average pod weight (g), No. primary of branches at harvest, root nodules at 60 days, plant height (cm) at 40 days and days to picking 1. Contribution of individual traits towards the total divergence was found maximum for pod yield q/ha, pod yield (g/plant) No. of leaves at 60 days, days to picking 2, Pod length (cm), No. of seeds per pod and dry of 100 seed (g).

Conclusion

Mean performance values showed that all the characters have significant difference for all the 31 characters of 22 genotypes of garden pea. Phenotypic coefficient of variance (PCV%) was higher than the genotypic coefficient (GCV%) of variation for all traits indicating that environmental factor influencing their expression and their susceptibility to environmental fluctuations slightly. Variability studies suggest that all the characters revealed that direct selection is more effective to improve all the characters in garden pea. Pod yield q/ha expressed highly significant and positive correlation with pod yield (q/ha) with pod yield (g/plant), shelling %, chlorophyll content, days to maturity, days to picking 2, days to 50 % flowering, average pod weight (g), No. primary of branches at harvest and days to picking 1, which indicates that these characters play the significant role to increase the pod yield (q\ha.). It is concluded that Pusa Praghati, Kashi Nandini, sehore local, Arka Priya, murdi local, punjab 89, kashi Samarth, Sadan khedi local, Mungaoli local, Raipura local, Jamoniya local genotypes shows better result in terms of yield attributing characters. Therefore, these varieties can be used further in breeding improvement programme in garden pea.
