Abstract:
A field experiment was carried out during Rabi season 2022-23 to assess the genetic variability, heritability and genetic advance among 15 genotypes of vegetable pea in randomized block design (RBD). Observations on thirteen characters viz., days for first flower emergence, days to 50 percent flowering, days to first pod formation, days to first pod picking, plant height (cm), 100 seed weight, shelling %, average pod weight (g), pod length (cm), number of seeds per pod, yield per plant (grams/plant), yield per plot (kg/plot) and yield per hectare (tons/ha) were taken for the assessment. The results of ANOVA showed significant differences among the genotypes for all the characters indicating the existence of wide spectrum of variability among the genotypes. The phenotypic coefficient of variation (PCV) were comparatively higher than genetic coefficient of variation (GCV). The high estimates of the PCV were obtained for yield per plot followed by yield and yield per plant, whereas estimation of GCV was high in case of yield and yield per plant. High heritability was recorded for all the characters under study except average pod weight. The highest genetic advance as percent of mean was exhibited by yield per plant (g) followed by yield (t/ha), plant height (cm) and days to first flower emergence. So, these characters should be preferred during selection of traits in different breeding and crop improvement programs to develop high yielding and more successful Varieti.
