ABSTRACT

Studies on the polymorphism of Oil Palm pollen Isocitrate dehydrogenase - IDH from palms originating from African populations, revealed the existence of four alleles in one locus. In this work, a new allele, named IDH* 5 was detected after starch gel electrophoresis of pollen extracts from open-pollinated bunches from 90 palms of 31 progenies sampled from four localities of the southern coast of Bahia state, Brazil.

Keywords: Oil palm; Elaeis guineensis; Isocitrate dehydrogenase; Isozyme variant.
