ABSTRACT
Biochemical and molecular markers have several applications in plant genetics. They allow us to observe closely the polymorphism of DNA sequences at a certain number of sites or loci spread across the genome. More precisely, biochemical markers reveal the polymorphism of sequences of certain proteins and thus, indirectly, the polymorphism of DNA sequences from which they are translated. Molecular markers directly reveal the polymorphism of DNA, the targeted sequences corresponding or not corresponding to the coding sequences.
