Abstract: An experiment was conducted at ICAR-Indian Agricultural Research Institute (IARI), Regional Station, Kalimpong to evaluate the performance of Darjeeling mandarin on different rootstocks. Experiment was laid out in Randomized Block Design (RBD) with 7 treatments and 3 replications. Treatment details were T1- Trifoliate orange T2- Rough Lemon, T3- Rangpur Lime, T4- Sour Orange, T5- Soh Sarkar, T6- Carrizo Citrange, T7- Taiwanica. With regard to budding success, Treatments T2, T3, T4, T5, T7 were on par at 5% level of significance whereas lowest budding success (61.00 %) was observed in T6 (Carrizo citrange). Highest rootstock length (12.06 cm), scion length (23.01 cm), number of leaves (15.77 cm) was recorded in Rough lemon which was found to be on par with Rangpur lime at 90 DAB (Days after budding). Maximum graft diameter (1.38 cm), shoot diameter (1.14 cm), shoot length (44.01) and leaves/plant (60.12) was recorded in Rough lemon at 180 DAB (Days after budding). The rootstocks rough lemon and rangpur lime were found to show vigorous effect on Darjeeling mandarin.
