    Abstract

    The mode of inheritance of chloroplast and mitochondrial DNA has been determined in intergeneric hybrids between C. papaya and four different Vasconcellea species by employing a restriction fragment length polymorphism analysis of a PCR-amplified chloroplast and mitochondrial DNA region. Artificial F-1 hybrids were produced between a female specimen of C. papaya and male specimens of either V. parviflora, V. goudotiana, V. cundinamarcensis or V. quercifolia. The hybridization patterns of all hybrids correspond in all cases with that of the C. papaya mother, and are different from that of the paternal Vasconcellea species, thus indicating the maternal inheritance of cpDNA and mtDNA in intergeneric hybrids between C. papaya and wild relatives of the Vasconcellea genus.
