The crosses for the experiment were created during Rabi 2018-2019, and a field experiment was carried out at the vegetable research farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, U.P. during the 2019–2020 Rabi season. The 13 different genotypes of garden peas (10 lines and 3 testers) that were collected from Chandra Shekhar Azad University of Agriculture and Technology's vegetable research farm in Kanpur made up the experimental material. During the 2019 Rabi season, a set of thirty crosses (10 lines and 3 testers) were created. A respectable amount of crosses was tried in order to generate enough F1 seed in each cross. Using a Randomized Block Design (RBD), 13 genotypes of vegetable pea were assessed for genetic progress and genetic heritability. Notes on eleven characters, namely Days until 50% flowering plant height (cm), number of branches per plant, length between nodals, number of seeds per pod, number of pods per plant, green pod yield per plant (g), first fruiting node, and shelling percentage (%) were collected in order to conduct the assessment. Significant variations were found across the genotypes for every attribute in the ANOVA findings, suggesting a broad range of variability among the genotypes. Every character in the current study shown a high degree of heritability. With the exception of shelling percentage, days to 50% flowering, and pod width, all of the characters demonstrated high heritability and high genetic advancement; in contrast, the characters representing shelling percentage, days to 50% flowering, and pod width demonstrated moderate genetic advance and high heritability. These characters displayed the least amount of G × E interaction and were least affected by their surroundings. From a breeding standpoint, only the heritable portion of total variation matters. Therefore, in various breeding and crop improvement initiatives, these qualities should be given preference when selecting traits in order to generate high yielding and more successful varieties.
