The vigour, blooming, yield, and biochemical features of seventy mango hybrids, including their parents,‘Amrapali’ and ‘Sensation’, were evaluated. The hybrid ‘H-13-5’ had the greatest plant height (10.11m), wherestem girth was maximum in ‘H-1-6’ (132.21cm), and ‘H-13-1’ had the largest canopy spread (9.77 m). The hybrid‘H-13-4’ exhibited the highest bark-wood ratio (7.59), signifying a higher percentage of mature wood surroundingthe entire stem. Hybrid ‘H-1-9’ had the highest stomatal density (797 stomata/mm2) as a dwarfing trait. Regardingreproductive characteristics, hybrid ‘H-11-4’ produced the maximum number of fruits (2.51) per panicle. Witha more significant fruit retention percentage of 62%, the hybrid ‘H-11-1’ showed improved fruit retention onthe tree. The tree with the higher fruit output, hybrid ‘H-1-8’, produced 43 kg of fruit per tree. The hybrid ‘H-1-5’ produced the maximum size of fruits (317 g/ per fruit). These signify that the resultant hybrids have a lotof potential for future breeding and commercial exploitation because of their advantageous economic traits.
