Abstract

                                Studies on different genetic parameters namely, genotypic and phenotypic variances. genetic coefficient of variation. phenotypic coefficient of variation. herita- bility, expected genetic advance, and genetic gain were conducted on forty strains of guar (Cyamopsis tetragonoloba (L.) Taub.) High genotypic and phenotypic varian- ces were observed for number of oods per plant and plant height. Highest genetic and phenotypic coefficient of variations were recorded for number of branches per plant. Heritabitity was moderate to high in almost all the characters studied except gum content and grain yield per plant. Number of branches per plant, number of pods per plant and number of clusters per plant exhibited high genetic gain. These characters also had high heritability estimates.
