Characterization of sucking type mango genotypes under sub-tropics of Punjab

Abstract

Nine sucking mango genotypes were evaluated for the qualitative and quantitative characteristics of plant, leaf, inflorescence, flowering and fruit morphometric as per IPGRI Mango Descriptor. The colour measurements of young emerging leaves were recorded with colour flex meter and it varied from brownish-green to purplebrown. In all genotypes, full bloom was observed in the last week of March, while fruit set from 25th March to 3rd of April. Wide variability among the sucking mango genotypes was observed with respect to fruit length/breadth ratio (1.02 - 1.84), fruit weight (77.3 - 203.7 g), fruit yield (34.7 - 100.5 kg/tree), TSS/acid ratio (21.3 - 51.7) and pulp/stone ratio (1.81 - 2.72). The incidence of mango malformation varied from 4.2 per cent in GN3 to 15.1 per cent in GN4. The variability in the existing germplasm can be exploited for strategic future mango improvement programmes.
