The aim of this study was to determine average daily gain in physico-chemical characteristics, yield efficiency, Flesh thickness, Stone size, Pulp stone proportion and Leaf size of some apricot cultivars at commercial harvest. Correlation analysis was conducted to assess change in yield efficiency and flesh thickness with regard to leaf size. Bearing apricot trees of 6 different cultivars viz. Charmagz, Conian Italy, Roundel, Kaisha, Australian Sweet and Quetta of uniform age group (8 years), vigour and agronomic practice were investigated. Single tree in each cultivar constituted an experimental unit and each cultivar was replicated 4 times. Average Daily Gain (ADG) in physico-chemical traits, yield efficiency and other characteristics of apricot cultivars revealed that the maximum extent of average daily gain in fruit weight, length, diameter, volume and acidity can be 0.393 (g), 0.422(mm), 0.435(mm), 0.385 (cm3) and 0.0219 (%) respectively, in cultivar Conian Italy. Maximum gain in TSS (0.256 %) was recorded in cultivar Charmagz while as minimum in cultivar Quetta (0.132%). Cultivar Charmagz noticed maximum average daily gain in ascorbic acid (0.173 mg/100g), reducing (0.60 %), non-reducing (0.107%) and total sugars (0.178). Cultivar Conian Italy recorded highest yield efficiency (0.177kg/cm2) while as lowest (0.120 kg/cm2) in cultivar Roundel. Maximum flesh thickness was observed in the fruits of cultivar Australian Sweet whereas minimum in Roundel. Stone weight was recorded highest (3.09g) in cultivar Kaisha and minimum (1.84g) in Quetta. Maximum pulp stone proportion (14.75%) was recorded in Australian Sweet. Maximum leaf size (27.55 cm2) was recorded in Conian Italy whereas minimum was recorded in Roundel. Both yield efficiency flesh thickness of all the cultivars showed significantly (P < 0.05) high correlation with the leaf size (r2= 0.61 and 0.98, respectively)
