Abstract : An experiment was laid out in Bhagalpur (Bihar, India) in 1980 and observations were recorded during 1996-99 to determine the long-term effect of different rootstocks on growth, yield, fruit quality and leaf mineral composition of mango cv. Bombai. The rootstocks used were Mylepalian, Puttu, Kurukan, Kalapady, Latra, One tree seedling and Random seedling. Latra recorded the least growth (plant height and spread), followed by Mylepalian. The highest plant height was recorded in Random seedling. Latra also recorded the lowest fruit yield per plant, whereas One tree seedling recorded the highest. There was no significant effect of different rootstocks on fruit quality attributes (total soluble solids, acidity, total sugar and vitamin C). Differences due to rootstocks in the leaf nutrient composition with respect to N, P, K and Ca were significant. Latra showed the lowest level of nutrients, whereas One tree seedling resulted in the highest leaf nutrient composition. On the basis of growth parameters, it may be concluded that Latra (monoembryonic) and Mylepalian (polyembryonic) may be used as rootstocks for high density planting under subtropics of Bihar.
