Conteúdo: 	Papaya ringspot virus (PRV) is a major limiting factor for papaya production throughout tropics and subtropics. The unavailability of PRV-resistant papaya varieties, the difficulty of eradication, and the restricted host range of PRV make cross protection an attractive method of controlling this virus. Two mild virus mutants. PRV HA 5-1 and 6-1, that produce no conspicuous symptoms on papaya were obtained from nitrous acid induction. The mutants provide a high degree of cross protection under greenhouse conditions. Results of small-plot and large-scale field tests indicate that these are hihgly valuable strains. The application of cross protection for control of PRV has become a routine practice in Taiwan since 1984.
