The success of any breeding programme depends upon the amount of variability present for different characters in a population and its efficient management. The genetic coefficient of variation is a useful measure of the magnitude of genetic variance present in the population. However, estimation of genetic variability alone cannot indicate the possible improvement that could be achieved through selection, but it should be used in conjunction with heritability and genetic advance. High heritability combined with high GAM was observed for most of the characters especially for shelling percentage, sound mature kernel weight and pod yield per plant. High heritability coupled with moderate genetic advance as percent of mean (GAM) was recorded for protein and sound mature kernel weight. Oil content showed high heritability with low GAM. It was also observed that variability and heritability for chlorophyll content and yield in 40 peanut genotypes and reported wide variability and moderate heritability values for chlorophyll content and seed weight per plant. High GCv, PCV and heritability and genetic advance were noticed for harvest index and its component traits viz., pod yield per plant, number of branches per plant and sound mature kernel percentage.
