Genetic variability and correlation study for yield and yield attributing characters of garden pea (<i>Pisum sativum</i> L. var. <i>hortense</i> Asch.) under valley conditions in Garhwal

Genetic variability and heritability of a character are necessary for a successful exploitation in breeding programme. These parameters help to identify relation between traits and characters affecting the yield that are important for improvement of varieties through breeding programme. The study was carried out during winter season 2023-2024 at Horticultural Research Centre, Department of Horticulture, School of Agriculture and Allied Sciences, Chauras Campus, Hemvati Nandan Bahuguna Garhwal University, Srinagar Garhwal, Uttarakhand. Twenty-eight genotypes were used including one check cultivar. The study on components of genetic variability showed high heritability and genetic advance over mean for traits such as plant height, number of primary branches, average pod weight, and seed index, indicating considerable variation. A positive correlation of yield of green pods per plot with plant height, average pod weight and seed index was obtained showing their importance in selection for yield improvement and breeding programmes of garden peas.
