| Outline of Final Research Achievements |
To breed virus resistant papaya, intergeneric hybrids between papaya and mountain papaya, and backcross plants between intergeneric hybrids and papaya were developed. Both intergeneric hybrids and backcross plants showed resistance to papaya leaf distortion mosaic virus. According to the RAD-seq analysis of intergeneric hybrids and the previous reports, we identified a STK gene as candidate of virus resistance gene and converted it into a CAPS marker which can be usable for papaya breeding.
