Abstract: The effect of rootstock (Troyer citrange, Karna Khatta [Citrus karna] and Sohsarkar) on fruit drop was investigated for mandarins grown in high density plantings in India. Plants on all 3 rootstocks showed 2 distinct waves of drop (a very heavy drop in April-May and severe preharvest drop in September-October). Plants on Troyer citrange showed the lowest fruit drop in April-May and the highest pre-harvest fruit drop compared with the other rootstocks. Overall fruit drop was highest in Sohsarkar (86.41%) and lowest in Troyer citrange (69.79%).
