Autopolyploidy versus Allopolyploidy and Low-density Randomly Amplified Polymorphic DNA Linkage Maps of Sweetpotato

Low-density randomly amplified polymorphic DNA (RAPD) markers of sweetpotato [Ipomoea batatus (L.) Lam.; 2n = 6x = 90] were constructed from 76 pseudotestcross progenies obtained from ‘Vardaman’ x ‘Regal’. Of 460 primers, 84 generating 196 well-resolved repeatable markers were selected for genetic analysis. ‘Vardaman’ and ‘Regal’ testcross progenies were analyzed …
