Abstract: The present study seeks to estimate the genetic variability and heritability of desirable metric characters of Talinum triangulare (Jacq.) Willd. Forty two F1 population of Talinum triangulare (Jacq) Willd were planted in the field at the teaching and research farms of the Michael Okpara University of Agriculture, Umudike, Nigeria and studied for variation and heritability. Variance analysis indicated that phenotypic characters were significant (p<0.01) for such metric characters as final plant height, total number of leaves per plant, leaf area and fresh shoots yield. Partitioning the variance component revealed that the environment showed major effects on the performance of characters like total number of leaves per plant, leaves at flowering, final plant height and basal diameter. While total number of branches per plant and flowering, plant height at flowering, number of days to 50% flowering, leaf area and fresh shoots yield were genetically influenced. Considering the wide variability and high heritability estimates obtained, progress could be expected from selection based on plant height at flowering, number of branches per plant, days to 50% flowering, leaf area and fresh shoots yield.
