Variability and correlation studies on fruit quality traits in mango seedling progenies under north eastern transitional zone of Karnataka

Abstract

The investigation was carried out to study the variability in physico-chemical parameters of among the seedling progenies of mango tree and correlation studies between quality parameters of the elite seedling progenies of mango in major growing parts of Bidar district. Among the 61 seedling selections selected in the present investigation, ‘YMS-05’ had the highest values for TSS (24.00 oBrix) and non-reducing sugars (14.39%). 'CMS-47' had the maximum amount of total sugar (20.9%) and reducing sugars (7.49%) while, the lowest titrable acidity (0.14%) and the highest TSS to acid ratio (160.00) were recorded in 'CMS-25'. The highest ascorbic acid content was noticed in 'CMS-01' (84.86 mg/100g pulp), The maximum carotenoid content was noticed in 'CMS-63' (6496.36 µg/100g). The TSS was positively correlated with total sugar, reducing sugar, non- reducing sugar, ascorbic acid content and TSS to acid ratio.
