Summary
Forty one populations of sixteen Argentine races of maize were studied with electrophoretic techniques. Seven isozyme systems coded by fifteen gene loci were used for studying the genetic variability within and among races and populations. In the whole sample was found that the variation within populations represented 78% of the isozymic variability, the variation among races was 14% while the variation among populations within races was only 8%. Cluster analysis and Principal Component analysis indicated that most races were closely related. ‘Cateto Amarillo’, ‘Cravo’ and ‘Perla Mediano’ were the most distinctive of the Argentine races.
