Estimation of Heritability and Genetic Advance for quantitative traits in Pea (Pisum Sativum L.)

A field experiment was conducted at Vegetable Research Centre of G.B.P.U.A. & T., Pantnagar, during 2010 and 11 on mollisols (sandy loam in texture having 7.62 pH) of Uttarakhand. For the study of genetic advance and heritability, the trail on vegetable pea (Pisum Sativum L.) was conducted. On the basis of recorded data, Genotypic Variance (σ2g), Phenotypic Variance (σ2p) and Environmental Variance (σ2e) calculated for calculation of the heritability and genetic advance was calculated by the suitable methodology with the help of SPSS and SPAR. The total 10 characters was taken under study Viz. days of first flowering, nodes to first flowering, number of primary branches per plant etc. The results revels that heritability (broad sense) Ranges between 99.97% to 22.50% highest heritability was recorded for days of flowering as 99.97% and lowest in number of seed per pod (22.50%). The genetic advance was recorded in percent of mean. The genetic advance as percent of the mean was height in 100- seed weight (29.28%) followed by number of primary branches per plant (26.94%) and lowest in number of per pod. (6.9%).
