摘要：

The current investigation was undertaken on "transmission of resistance to papaya ringspot virus (PRSV) in intergeneric populations of Carica papaya and Vasconcellea cauliflora". In this study, the three F-2 populations raised from S-1 inbreds were screened and the desired male and female plants were selected for sibmating. The F-2 populations of various combinations segregated for susceptibity and resistance to papaya ringspot virus in two different ratios. The cross combination CO 7 x V. cauliflora (CO7V3) exhibited a 15:1 ratio (duplicate gene action) and the crosses Pusa Nanha x V. cauliflora (PNV9) and CP 50 x V. cauliflora (CPV23) exhibited 13:3 ratio (inhibitory gene action). The study revealed multi-genic inheritance of resistant to PRSV which uniquely exhibit inter-genic interactions. (C) 2015 Elsevier B.V. All rights reserved.
