A study was carried out at the Department of Vegetable Science, Horticultural College and Research Institute, Periyakulam, during 2019–20 to assess the genetic variability, heritability and genetic advance of important quantitative and qualitative traits in fifty-two perennial moringa genotypes. Analysis of variance revealed a significant differences for all traits. High genotypic and phenotypic coefficients of variation were noticed for pod yield, the number of pods per tree, total carotenoids, iron and pod weight indicating maximum variability among the different genotypes. High estimates of heritability coupled with high genetic advance obtained for all the traits except crude fibre content indicating the presence of additive gene effect which showed the effectiveness of selection for these traits. Presence of high heritability coupled with moderate genetic advance for crude fibre content revealed that the straight selection has a limited scope for further improvement of the trait. Among fifty two genotypes PKM MO-55 has the highest iron content (7.20mg/100g), number of pods/tree (306.50) and pod yield (36.47 kg/tree).
