The Solanum brevidens genome (2n = 2x = 24) was examined with randomly applied polymorphic DNA (RAPD) markers in a second backcross population derived from a S. brevidens + S. tuberosum somatic hybrid. RAPD markers cosegregated into 12 different S. brevidens synteny groups. Most synteny groups were nonrecombinant. However, nearly 40% of the S. brevidens synteny groups detected in this population were recombinant deletions that carried at least one, but not all, synteny group-specific RAPD… CONTINUE READING
