title: Genetic variation in monoploids of diploid potatoes and detection of clone-specific random amplified polymorphic DNA markers.
abstract: Randomly amplified polymorphic DNA (RAPD) markers have been used to study the genetic variation among androgenetic monoploids of diploid Solanum species. Cluster analysis of pairwise genetic distances was used to construct a genetic relationship among anther donor and anther-derived potato plants. The clustering based on Rogers' distances resembled classifications based on parental origins and hybrid combinations. Six of the 32 RAPD primers used resulted in the selective amplification of DNA fragments which were polymorphic between the two S. phureja parental clones, 1.22 and A95. It should be possible to construct a genetic linkage map, without making crosses, using monoploids derived from a single heterozygous diploid clone and RAPD markers.
