D.  aControl of papaya ringspot virus by cross protection.h[electronic resource]  c1988  aPapaya (carica papaya L.) is one of the most widely grown and economically valuable fruits of the tropics and subtropics. This large herbaceous, dicotyledonous plant with a single stem and a crown of large, palmately lobed leaves grows fast and yields fruit 8-10 months after being transplanted in the field. The extensive adaptation of the plant and the wide a acceptance of the fruit offer considerable promise for local and export markets. Like banana, pineaple, and mango, papaya is oneof the important cash crops in the tropics and subtropics. A destructive disease caused by papaya ringspot virus (PRV) is a major obstacle to wide-scale planting of this fruit tree. PRV has been reported as a major limiting factor for growing papaya in areas of Hawaii, Florida .  aMamão1 aGONSALVES, D.1 aWANG, H. L.1 aNAMBA, R.1 aCHIU, R. J.  tPlant Diseasegv.72, p.375-380, 1988.
