Papaya: The Versatile Tropical Fruit
Papaya (Carica papaya L) is a versatile tropical fruit with its usage ranging from consumption, cosmetics, to pharmaceuticals. In 2020, it was the third most-produced tropical fruit crop in the world. Papaya is a trioecious herbaceous plant with distinct flower and fruit morphological appearances. The fruits from hermaphrodite papaya are favorable for both consumption and processing due to their superior quality. Papaya has a genome size of 372 Mb and chromosome of 2n =18. The male and hermaphrodite papaya have XY and XYh sex chromosomes, respectively, while the female has XX. Using omics and bioinformatics approaches, papaya cultivars with desired fruit quality can be selected and identified from germplasm for incorporation in breeding programs. Papaya production can be done either in open fields or under protected cultivation. Open field cultivation provides for large-scale production, but with the disadvantages of variability in fruit yield, quality, and limitations on growing and harvesting seasons. Under protected cultivation, papaya can be cultivated in all seasons, whilst delivering higher yields. Conversely, multidisciplinary approaches with selected papaya cultivars, good farm management, and suitable conditions provide high yields of quality fruit for both consumption and processing, whilst minimizing the adverse effects related to environmental conditions.
