Papaya breeding for PRV resistance

, : Papaya breeding for PRV resistance. Acta Horticulturae ( 370): 27-31

Moderate genetic resistance to papaya ringspot potyvirus (PRV) in pawpaw germplasm was used in conventional breeding programmes in Florida and Hawaii, USA, to create PRV-tolerant cultivars that are a compromise between useful resistance and acceptable fruit quality. In Hawaii, phenotypic recurrent selection and RAPD marker assisted selection were used to improve fruit quality and PRV resistance in populations derived from crossing a virus-tolerant parent with commercial cultivars.
