[The genetic polymorphism of cereals demonstrated by PCR with random primers]

Polymerase chain reaction of DNA amplification with the use of random primers is a new approach in investigations of genome specificity. Nucleotide sequences that showed polymorphism in RFLP analysis were used as primers. Optimal temperature conditions and Mg2+ concentrations were determined for studying inter- and intraspecific DNA polymorphism in the most important cereals.
