Abstract:

Dashehari is an important export variety of mango (Mangifera indica L.) for its attractive appearance, excellent taste and pleasing flavour which is cultivated on a commercial level and propagated through vegetative means to ensure multiplication of true to type plants. Despite this, intra-varietal variability is reported in certain varieties although limited. In the present study, 45 Dashehari trees, 25-30 years in age from 15 different orchards in 2 blocks viz. Malihabad and Mall from Agri-Export Zone for mango of Uttar Pradesh, India were selected for study. The significant intra-varietal variability in stone weigh was observed to range from (24.17 to 33.50g), pulp:stone ratio (4.36 to 8.04), stone length (8.99 to 11.75cm), stone width (2.72 to 4.14cm) and stone thickness (1.44 to 1.93cm), kernel length (3.65 to 6.65cm), kernel width (1.46 to 4.13cm) and kernel thickness (1.04 to 2.07cm). The intra-cultivar diversity was observed in terms of PCV (Phenotypic coefficient of variation), GCV (Genotypic coefficient of variation), heritability (h2), genetic advance (GA) and genetic advance as percent of mean (GAM%) for stone and kernel parameters. Kernel width showed highest PCV (22.15%) and GCV (19.65%). The highest heritability (85.50%) and genetic advance (2.80%) was observed from kernel length. However, maximum GAM% (75.35%) was observed for kernel thickness which indicated predominance of additive gene action for these parameters and these parameters may be considered for intra-cultivar diversity analysis of Dashehari mango for further crop improvement through selection.
