PERFORMANCE OF MANGO CULTIVARS UNDER SUB-MOUNTANE ZONE OF SUB-TROPICS OF INDIA

Ten grafted mango cultivars namely ‘Alphonso’, ‘Mallika’, ‘Malda’, ‘Kishan Bhog’, ‘SB Rampur’, ‘Fazri’, ‘SB Chausa’, ‘Langra’, ‘Dashehari’ and ‘Amrapali’ were evaluated for their performance in terms of vegetative growth, flowering and fruit physico-chemical characteristics.
Maximum stem girth and canopy volume was noted in ‘SB Rampur’ while minimum in ‘Kishan Bhog’ and ‘Amrapali’ indicating dwarfness and may be selected for high density plantation.
Leaf color of young emerging leaves was brownish green to purple brown as recorded with Color Flex EZ spectrophotometer Hunter Lab., USA. Full bloom and fruit set in different mango cultivars was observed in the last week of March and 1st week of April, respectively, however, hermaphrodite flowers ranged from 21.5 to 51.5%. Fruit yield and lower incidence of floral malformation (%) was observed in ‘Fazri’. The fruit weight was maximum in ‘Mallika’ and minimum in ‘Malda’. Cultivar ‘Langra’ had shown the highest pulp percent content followed by ‘Alphonso’ and ‘Dashehari’. Total soluble solids of juice varied from 20.4% in ‘Amrapali’ to 14.3% in ‘Langra’. Wide variability in terms of juice acid content, TSS/acid ratio, sugars (reducing and non-reducing) and ascorbic acid among different cultivars was also observed.
On the basis of fruit maturity, cultivars were classified as early season – ‘Alphonso’, ‘Malda’; mid-season – ‘Kishan Bhog’, ‘SB Rampur’, ‘Langra’, ‘Dashehari’; and late season – ‘SB Chausa’, ‘Fazri’, ‘Mallika’, ‘Amrapali’. It is found that ‘Langra’, ‘Dashehari’, ‘Amrapali’ and ‘Alphonso’ are promising under sub-mountane zone of sub-tropical conditions of north India.
