"Sinta" is a yellow hybrid papaya with very good fruit quality that is moderately tolerant to papaya ringspot virus (PRSV). Nutritional and growth regulator requirements for micropropagation of this papaya hybrid were established using varying levels of NAA, BA, GA3, sucrose and 2 basal media (MS and De Fossard). Parameters used in evaluating in vitro growth response were number and length of internodes, number of leaves, shoot length and shoot weight. Optimum shoot growth was obtained using full-strength MS 0.125 uM NAA 0.125 uM BA 10 uM GA3 + 90 mM sucrose. Full-strength De Fossard medium containing similar hormonal and sucrose levels gave a comparative response. Micropropagation opens the possibility of producing virus-free "sinta" for transport to PRSV-free islands.
