A field experiment was carried out to determine the genetic variability, heritability and Genetic advance present in twenty-two genotypes of garden pea during Rabi season 2021-22 at ICAR-Krishi Vigyan Kendra, Babbur farm, Hiriyur. The experiment was laid out in Randomized Complete Block Design with two replications. Observations were recorded on various yield and yield contributing characters. In general, the magnitude of the phenotypic coefficient of variation (PCV) was greater than that of the genotypic coefficient of variation (GCV) and the narrow difference between them indicates less environmental influence on the expression of the trait. High PCVand GCV (>20%) were recorded on plant height, number of branches per plant, pod thickness, number of pods per plant and non-reducing sugars which indicates the presence of high genetic variation and scope for effective improvement. All the characters studied in this experiment showed high heritability (>60%) in a broad sense coupled with high genetic advance as per cent over a mean (>20%) except for days to first flowering, days to 50 per cent flowering and days taken for first picking. This indicates the existence of additive gene action and the need for population improvement through selection. The genotypes that exhibit specific traits can be used in a hybridization programme |
