Papaya (Carica papaya L.) is one of the most important fruit cultivated throughout the tropical and subtropical regions of the world. The ripe fresh fruit of papaya is delicious and used as table fruit. Green fruits are diuretic and mildly laxative and are very commonly used as vegetable in each section of society. Papain, prepared from dried latex of immature fruits, is a proteolytic enzyme similar in action to pepsin and is used for manufacture of drugs, meat tenderizing, manufacturing of chewing gum and in leather industry.
There is great demand of the quality seeds of the released varieties and hybrids from Public and private sector. Therefore, it is imperative to know the various hybrids available in the country with their important traits.
Varietal wealth: Status of hybrid papaya cultivation in India (varieties from public/private sector) is being elaborated hereunder under respective heads.
Public Sector Hybrids
