Abstract: The present application relates to papaya plants having increased resistance to the papaya ringspot virus as compared to a wild type plant due to a mutation in the eukaryotic translation initiation factor 4e and/or eukaryotic translation initiation factor iso4e gene leading to non-functional eukaryotic translation initiation factor 4e and/or eukaryotic translation initiation factor iso4e proteins. Methods of producing such papaya plants having increased resistance to the papaya ringspot virus are described.

Abstract: Papaya plants containing mutant allele EWSMHP, which confers production of highly hermaphroditic progenies upon selfing of its hermaphrodite plants and also production of highly hermaphroditic F1 progenies when crossed with normal female and normal hermaphrodite papaya plants, are disclosed. The invention relates to the seeds of papaya plants having mutant allele EWSMHP, to the plants and plant parts of papaya plants having mutant allele EWSMHP and to methods for producing progeny of papaya plants having mutant allele EWSMHP. The invention also relates to methods for producing a papaya plant having mutant allele EWSMHP containing in its genetic material one or more transgenes and to the transgenic papaya plants and plant parts produced by those methods. The invention also relates to papaya cultivars or breeding cultivars, and plant parts derived from papaya plants having mutant allele EWSMHP.
