Abstract: Papaya is a highly heterozygous fruit crop, therefore there is a need for multiplication of plant through Tissue Culture for bearing fruits in almost all the plants. Keeping these facts in view the multiplication of Papaya Carica papaya L. cv. Pusa Delicious through Tissue Culture were studied in the Tissue Culture Lab of the Department of Horticulture, Sardar Vallabhbhai University of Agriculture & Technology, Meerut, (U.P.) during the year 2016-2017. The experiment was conducted in two way factorial design with 10 treatments comprising 5 levels of NAA (0.01, 0.1, 0.5, 1, 2 and 3 ppm) and 5 levels of IBA (0.1, 0.5, 1, 2 and 3 ppm) replicated thrice. The different concentrations of Auxins alone are applied. The effect of these treatment was observed among the different concentration of the bio-regulators, In case of rooting of explants, the effect of IBA and NAA was studied with the half dose of CHU (N6) media, NAA 3 ppm was most effective in terms of root induction in explant which induced the root just in 11.66 days. IBA 1 ppm was best in inducing maximum number of roots. Hence based on the result obtained from the investigation it can be concluded that the NAA 3 ppm is the best for early rooting and IBA 1 ppm is ideal for obtaining maximum numbers of root in CHU (N6) media for Papaya (Carica papaya L.) tissue culture.
