Papaya Breeding; Recent Advances and Future Prospects

Mowmita Sarker
MS Student, Department of Genetics and Plant Breeding, BSMRAU, Gazipur-1706

Abstract/ Executive Summary:

Papaya [Carica papaya L.] is one of the most popular and nutritious tropical fruit in the world, and it is gaining popularity among the growers day by day. Papaya breeding strategy such as popular germplasm of papaya, hybridization and heterosis, mutation breeding, breeding steps followed in Malaysia, molecular markers for sex determination in papaya, disease resistance breeding in papaya is reviewed. Papaya research achievement in breeding, molecular breeding in India, Malaysia, China, Brazil,Taiwan, Bangladesh are considered. Breeding challenges like nutritional quality development, sex determination in gene level, disease resistance, molecular diversity analysis is reviewed well. Future prospects of papaya research mainly emphases on papaya biochemical and molecular genetics and breeding, deepening the functional genome research to reveal special gene resources, enhancing the molecular genetic research for breeding. Conducting related species gene study to enhance disease resistant germplasm innovation, improving gene transformation technique to use exogenous genes, perfecting in vitro protocol should be integrated in the future papaya research in order to cope up with the currently existing ecological phenomena.

Objectives:

Objectives: • To know the breeding advances of papaya (past and present) • To review future papaya breeding scopes

Methodology:

This seminar paper is exclusively a review paper. So, no specific methods of studies are followed to prepare this paper. All facts and data were composed and recycled from secondary sources. This seminar paper has been prepared by reciting different books, journals, booklets, proceeding, newsletters, consultancy report which are available in the online libraries of BSMRAU & internet. Some information is collected from BARI and some private and international agricultural organizations. Maximum necessary supports were taken from internet searching. Finally, this seminar paper was prepared with the consultation of my respective major professor and honorable seminar course instructors.

Achievement/Findings:

In conclusion, like any other crops, the final objective of papaya breeding is to improve the quality and quantity of the product. Fruit nutritional quality development, manipulating the sex determination genes to find a static protocol for true-to-type hermaphrodite variety development, improvement of techniques to get disease resistant variety, search for variable germplasm by utilizing molecular diversity analysis, a standard in vitro protocol development are the papaya breeding objectives in the present stage and foreseeable future. Papaya breeding has achieved a tremendous advancement. Advanced technologies have been made for breeding of papaya. As previously conventional breeding and some molecular techniques were the only source of improvement. But nowadays, different advanced breeding approaches has been taken to improve quality. For future advancement different experiment should be done to make the crop more acceptable to the consumer. Major problems of this valuable tropical crop should be solved by applying advanced techniques. The advancing papaya breeding techniques, from individual selection to hybridization and advance molecular breeding, will benefit the current and future papaya breeding programs in the world.
