Abstract
Mango cultivars are mostly the result of selections from open pollinated chance seedlings of indigenous/introduced germplasm. Development of mango hybrid remains a major focus to boost local industry. Pakistan, being an important mango producing country developed a hybrid ‘Faiz Kareem’ by making a cross between two commercial mango cultivars i.e., Anwar Ratole X Chaunsa. These studies were carried out to compare the fruit ripening behaviour and quality of this new promising mango hybrid cultivar Faiz Kareem with its parents under ambient (28±2°C; 65-70% RH) conditions. Mature fruits of three cultivars were harvested randomly from a commercial orchard in district Multan, Punjab. During ripening, data on various physico-chemical characteristics including physiological fruit weight loss percentage, fruit softness, visual peel colour, titratable acidity, total soluble solids, sugars, vitamin C, and total carotenoids were recorded daily up to 7 days. Under ambient conditions all the cultivars took 7 days to ripe however, Faiz Kareem expressed better firmness, which indicates its potential for extended shelf life. Highest levels of total sugars (25.88%), total soluble solids (26.75°Brix) and total carotenoids (69.99µg g-1) were observed in Chaunsa while lowest in Faiz Kareem (23.71%
