Abstract:
The present investigation was conducted in a pre-established orchard named of All India Coordinated Research Project on Fruits at Regional Research Station, Gayeshpur, West Bengal from 2016 to 2018 to determine the genotypic and phenotypic correlation analysis of yield to estimate the contribution of most important characters towards yield. The genotypic (G) and phenotypic (P) correlation coefficients were worked out for twenty-six characters in sixteen mango cultivars. The genotypic correlation values were recorded higher than the phenotypic values. Fruit length (0.45, 0.49), fruit diameter (0.49, 0.51), fruit width (0.81, 0.83), pulp content (0.40, 0.41), stone length (0.45, 0.46), stone width (0.32, 0.35), stone weight (0.24, 0.25), seed length (0.23, 0.27), TSS: acid ratio (0.22, 0.27) and ascorbic acid (0.57, 0.59) showed positive association with yield both at phenotypic and genotypic levels. Total sugars, non-reducing sugars, reducing sugars, TSS: acid ratio, and ascorbic acid exhibited a significant positive correlation with TSS.
