Studies were conducted at Central Horticulture Experiment Station (ICAR-IIHR), Bhubaneswar during 2018 to 2020. Forty mango germplasm were studied for their genetic variability, heritability, and character association between yield and quality traits to estimate the contribution of traits towards yield. High genotypic (GCV) and phenotypic coefficient of variation (PCV) were recorded for yield, fruit weight, stone weight, pulp to stone ratio, peel weight, titratable acidity, total carotenoid, total flavonoid, total phenol which provide wide scope of improvement through selection. Moreover, high heritability and genetic advance were also observed in all characters. Peel weight, total carotenoid, total phenol and total flavonoid exhibited significant positive correlation with yield. Path analysis revealed that total flavonoid, peel weight, pulp to stone ratio, total carotenoid, total phenol, titratable acidity, stone weight, sex ratio, and total soluble solids had maximum direct effect on yield.
