A total number of genotype is 20, which is noticed across mango growing area of Dada Siba, district Kangra during 2022-2023. Selected genotypes were recorded with the tree height and trunk girth ranged between (8.1 to 22.2 m) and (0.36 to 2.4 m), with erect to spreading in growth habit, oblong to broadly–pyramidal in crown shape and sparse to dense density of foliage. There were very low variations observed in leaf and floral characters. Physical characters like fruit length (8.43 cm), fruit width (5.63 cm), fruit volume (170.57 cm3), fruit weight (164.93 g), pulp weight (101.60 g), peel thickness (1.25 mm), pulp: stone ratio (3.33), stone weight (33.03 cm), TSS (19.97 o B), acidity (0.26%) and ascorbic acid (31.60 mg/100g) were recorded. The estimates of PCV and GCV were high for pulp weight, fruit weight and pulp ratio. High heritability along with high genetic advance was observed in pulp weight, peel thickness, fruit volume, pulp:stone ratio, and fruit weight. Positive and significant correlation was observed in panicle width, fruit length, fruit width, fruit volume, pulp weight, peel thickness, pulp: stone ratio, stone length, stone weight, TSS and ascorbic acid. Path analysis studies showed that highest positive and direct effect was observed in pulp: stone ratio, seed weight and fruit length. Additionally, mango selection specialized for consumption purpose; table, pickling, or sucking has been determined. Overall, the current study has produced some superior mango selections of indigenous provenance that will serve as a valuable genepool in the future.EnglishThesis
