Papaya (Carica papaya L.) is an edible tropical fruit crop which has several medicinal and nutritional benefits. Sex type determination is more complicated in trioecious papaya at early seedling stage. Many hypothesis and research have been done to understand the genetics of sex determination. Various methods based on morphological, cytological traits and isozyme based markers have been utilized for sex identification, but none of these were efficient to solve the problem of sex identification in papaya at early seedling stage. Hence, sex-linked molecular markers including RAPDs, ISSRs and AFLPs have been developed in papaya and some advanced molecular markers like SSRs and SNPs have been developed in other plant species for sex identification, which indicated that these markers could also be utilized to differentiate male, female and hermaphrodite plants at early seedling stages in papaya.
