The field experiment was conducted at Horticultural Research Centre (HRC), old campus of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh, during 2011-12 and 2012-13. The study was concentrated on improvement in chemical traits, storage life and organoleptic quality of Ratol mango through application of biological regulators. Three biological regulators viz. Daminozide (50 ppm and 100 ppm), NAA (25 ppm and 50 ppm) and GA3 (25 ppm 50 ppm) were used. Water was used as control. TSS was found to be highest with 50 ppm NAA (24.44 °Brix) while control fruits had the minimum TSS (18.22 °Brix). A 29.86 % increase in TSS over control was registered in the present study with 50 ppm NAA over control. Titratable acidity was found to be maximum with 50 ppm GA3 (0.17 and 0.18 %), while control fruits had registered minimum titratable acidity (0.09 and 0.10 %) during both the years of investigation, respectively. Maximum increase of 100 % increase in titratable acidity with 50 ppm GA3 when compared with control. 50 ppm GA3 (23.39 %) had resulted in maximum increase in total. Storage life was also found to be maximum (12.16 days) with 50 ppm GA3.Lowest decay loss of fruits was recorded with 50 ppm GA3 (7.76 % and 8.30 %) during both the years of investigation, respectively. Maximum organoleptic score was obtained with 50 ppm GA3 (4.50 score value).
