This study was aimed to determine the rootstock effect on various horticultural traits like annual extension growth, tree volume, TCSA, fruit weight, fruit volume and yield were significantly affected by rootstocks and recorded maximum vegetative growth in trees on MM106 compared to M9 rootstock during the studies. The vegetative growth also varied significantly among cultivars which are genetically controlled feature in different apple cultivars. Fruits harvested from trees on MM106 were significantly higher in quality parameters like fruit weight, fruit volume and yield compared to those on M9 rootstocks. Different varieties on MM106 rootstock recorded significantly higher yield of 16.55 and 20.19 kg/tree compared to 13.7 and 18.65 kg/tree on M9 rootstock during the studies. Results showed that the Vista Bella on the MM106 rootstock had the most mean shoot length of the current year (39.97 cm), Vista Bella and Mollies Delicious observes highest tree volume (19.22, 19.76 m3) and the lowest tree volume (15.01, 17.45 m3) was recorded in Cooper IV. Cultivars also had a significant effect on the TCSA and record maximum (78.97 and 86.68cm2) in Starkrimson and minimum (59.92 and 60.18cm2) in Vista Bella and Cooper IV respectively during both years of studies. Fruit weight and fruit volume was maximum recorded in Starkrimson (218.04, 228.56 g and 171.36, 175.91 cm3) as compared to other cultivars. Among cultivars Vista Bella had maximum yield kg/tree (19.60 and 23.58 kg/tree) and Cooper-IV recorded lowest (7.20 and 12.81 kg/tree) during the study period.
