 ABSTRACT

The present investigation was carried out to estimate the extent of genetic variability, heritability and genetic advance for various quantitative traits among one hundred twenty genotypes and four check varieties of Fieldpea. Analysis of variance (ANOVA) revealed significant differences among all the genotypes for majority of the traits except number of primary branches per plant. Moderate to high level of genotypic coefficient of variance (GCV) and phenotypic coefficient of variance (PCV) were exhibited by the genotypes under study. In general, phenotypic coefficient of variance was found to be higher than their genotypic coefficient of variance but difference was quite meager, indicating negligible environmental influence on the expression of the characters. Higher estimate of GCV (30.414) was recorded for number of seeds per pod followed by seed yield per plant (28.874). Moderate to high level of heritability and genetic advance were reported for various quantitative traits under study. Maximum heritability in broad sense, were reported for seed yield per plant (99.78), seeds per pod (99.69), pod length (99.43), biological yield per plant (98.78) and harvest index (98.68). Maximum genetic advance in percent of mean was reported for seeds per pod (62.55), seed yield per plant (59.41), plant height (47.63), pod length (46.66) and harvest index (35.85). The characters such as seeds per pod, seed yield per plant, pod length and harvest index, showed high GCV, heritability and genetic advance would be more helpful in formulation of selection strategy for prediction of the gain under selection.

Keywords: Genetic variability, GCV and PCV, Heritability, Genetic advance and Fieldpea (Pisum sativum L. var. arvense).
