Evaluation of mango genotypes for jelly seed disorder

Abstract

Twenty mango genotypes including indigenous cultivars, exotic cultivars and hybrids were assessed for incidence of jelly seed disorder in artificially and tree ripe fruits during 2013 & 2014. In general, the jelly seed frequency and thickness of jelly pulp was found to be higher in tree ripe fruits compared to artificially ripened fruits. Among indigenous mango cultivars, the frequency of jelly seed was maximum in Dushehari (21.3 and 36%) and minimum in Gulabkhas Green (13.3 and 21.3%) in artificially ripened and tree ripe fruits. In exotic mango cultivars, the jelly seed frequency in artificially as well as tree ripe fruits was maximum in Tommy Atkins (12.0 and 17.3%). Among mango hybrids, Pusa Pratibha showed maximum frequency of jelly seed in artificially and tree ripe fruits (13.3 and 18.7%). However, Pusa Arunima was found to be almost free from this disorder and none of fruits had jelly seed in both artificially ripened and t ree ripe fruits.
