Conteúdo: | We selected 28 potential common bean (Phaseolus vulgaris L.) progenitors to determine their genetic diversity using RAPD technique. They were divided into two groups based on their type of storage protein (phaseolin); 18 of them had type "S" phaseollin and the other 10 had type "T' phaseolin. DNA samplesof all the cultivars were amplified in vitro with oligonucleotide primers of random sequences. A total of 276 amplification products, 144 of them being polymorphic, were obtained with 45 different primers. Multivariate analysis of these data divided the cultivars in to two groups and, in addition, allowed amore precise infra and intergroup distinction.
