[Genetic polymorphism of alkaline phosphatase and the resistance to Marek's disease virus].
Experiments were carried out with a total of 222 birds of the 5-A, 6-E, Ya-73, LL, and LS lines of the White Leghorn breed to find whether or not there existed any correlation between the alkaline phosphatase allels and the resistance to Marek's disease. The polymorphism of alkaline phosphatase was evaluated in the blood plasma of birds through horizontal electrophoresis in starch gel after G a hn e [3]. The resistance of the five egg laying lines of birds was found to be associated with the Akps allel, and their susceptibility - with the AkpF allel. No mortality with the homozygous gene type SS was established in the investigated lines except for a birds of the LL line. It was found that there existed full agreement of the results from the studies on broiler and laying lines concerning the exclusive resistance of birds of Akp SS gene type. This made it reasonable to believe that the indirect selection by resistance to the Marek's disease virus through the use of the Akps allel as a genetic marker was promising.
