ABSTRACT
A study was carried out among the local mango types in Odisha to explore
their genetic variations for further utilization in crop improvement, as the genetic
diversity serves as a way for the population to adopt the changing
edapho-climatic condition. From 17 districts of Odisha, a total of 548 seedling
trees were observed, but only 30 mango
elites were selected on the basis of organoleptic test for taste, flavor and aroma. Different
physico-chemical characters, like fruit size,
shape, colour, flavour, aroma and other characteristics, varied widely among these genotypes. The results of the study with respect to 30 numbers of local mango genotypes
revealed that the maximum individual
fruit weight (510 g) and pulp percentage (78.4%) was recorded in Kali. The
other desirable traits of the minimum stone
percentage (5.9%) and the maximum pulp to stone
ratio (12.5:1) was observed in Nakei. The minimum peel percentage (10.0%) and the maximum total soluble
solid (TSS) percentage (26%) was
recorded in the fruits of Mitha and Lori, respectively. Attractive fruit skin colour was observed in the genotypes
Nakei and Belua (yellowish), followed by Sundari (yellow with orange
tinge) and Kadalia (greenish
yellow). But in case of check mango cultivars Amrapali and Mallika, desirable
traits, like the maximum TSS, pulp
percentage, pulp to stone ratio and the minimum stone percentage was exhibited by
Amrapali, whereas Mallika had the maximum fruit weight.
The shape and skin colour are neither attractive nor preferred in both the
commercial cultivars, so above cited eye catchy traits can be incorporated into
these two superior mango genotypes from the local
genotypes to meet the market demand and export potential.
