 ABSTRACT

Twenty one moringa genotypes that were collected from different geographical regions of India were evaluated for variability, heritability and genetic advance for growth, yield and earliness characters and significant variations were recorded for the investigated traits. Widest range of variation was observed in pod length, number of pods per plant, single pod weight and pod yield per plant. Maximum genotypic and phenotypic coefficient of variation was observed for number of primary branches, pod length, number of pods per cluster, single pod weight and pod yield per plant. Higher value of heritability associated with high genetic advance as percent mean was observed for pod yield per plant, single pod weight, pod length, plant height, leaf length, pod girth, number of pod per cluster and number of branches per inflorescence. High heritability and genetic advance indicating additive gene action suggested that simple selection could be effective for the improvement of these traits.

Keywords: Moringa, Variability, Heritability, Genetic advance.
