Abstract
Phylogenetic relationships and genetic variation were examined in the genus Solanum based on the random amplified polymorphic DNA RAPD technique Genetic distances were estimated for 42 accessions from five subgenera Archaesolanum Minon Syn Brevantherum Leptostemonum Potatoe and Solanum This investigation provided new information and reinforced some suggestions from previous phylogenetic studies Analysis with random markers from the total genome clearly separated Solanum sect Dulcamara from the other members of Solanum subg Potatoe and indicated that among the analysed Solanum subgenera subg Solanum is most closely related to it The results suggest that Solanum sect Dulcamara should be excluded from Solanum subg Potatoe The subclusters formed by S rostratum and S citrullifolium appear to be distinct from the subcluster formed by the two accessions of S sisymbriifolium This topology indicates that Solanum sect Androceras and Solanum sect Cryptocarpum are fairly closely related although the data suggest that the two sections should not be maintainedThanks are due to the institutions and gene banks that provided seeds of the accessions analysed and also to the workers of the Georgikon Botanical Garden for raising the plants Thanks to Dr Lynn Bohs University of Utah USA for the critical review of the manuscript and for the beneficial advices
