摘要：

The genetic origin of cultivated papaya is not clear. Wild relatives of papaya (Carica papaya) from central southern America were investigated using isozyme and RAPD analysis. Seven other species (including six from the genus Carica) were found to be relatively distant from papaya providing no indication of the genetic origin of papaya. Isozyme and RAPD data gave similar measures of genetic similarity within this group. C. papaya was about 70% dissimilar to the other Carica species by both methods. The other Carica species had average dissimilarities around 50%. Two species, C. pubescens and C. stipulata were much closer to each other with similarities of 87% by isozyme analysis and 82% by RAPD analysis. Although both methods gave similar measures for genetic distance the large number of RAPD markers available made RAPD analysis more reliable for analysis of the extremes (e.g. closely related taxa may show no isozyme differences and distant taxa may show no isozyme similarities).
