The performance of Kinnow mandarin (Citrus reticulata Blanco) on six citrus rootstocks i.e. Citrumelo 4475, Citrumelo 1452, Volkamariana, Yuma citrange, Mithi and Rough lemon was studied during its sixth and seventh year of transplanting. Plant height was not affected by the rootstocks used. Maximum canopy spread and stem girth were recorded on Mithi while minimum canopy spread and stem girth were on Yuma citrange and Citrumelo 1452 respectively. Fruit set was not influenced significantly by the rootstocks used. Although fruit drops in grafted plants ranged from 35.75 - 93.33 per cent from button to pre- harvest drop, the rootstock means in each drop were non-significant. The highest mean number of fruits/plant was 285 fruits on Citrumelo 4475 and the lowest 77.5 fruits on Yuma citrange rootstock.
