Abstract
The genetic inheritance of four date-palm enzymes hasbeen carried out in 29 Tunisian cultivars. Our data provide evidenceof five polymorphic genes involving 12 alleles. It has been assumedthat either Pgm or Shdh are specified by three different alleles,while Got-1, Got-2 and Pgi-2 loci are biallelicgenes. On the other hand, analysis throughout progenies of twocontrolled crosses support significantly these hypothesis. In thewhole, results are in agreement with reports that describeddate-palm isozymes. Nevertheless, we assume that other alleleare involved in Pgm gene. Also, isozymes controlled by Got-2locus are of a dimeric structure. Opportunely, it can be establishedthat the resultant isoenzymes would constitute polymorphic markerssuitable to analyze the genetic diversity in date-palm.
