GENETIC VARIATION IN THREE BREEDS OF INDONESIAN LOCAL DUCKS BASED ON BLOOD AND EGG WHITE PROTEIN POLYMORPHISM

Abstract

A study of genetic variation of four blood protein loci and three egg white loci in three breeds of Indonesian local ducks (Magelang duck = MAD, Tegal duck = TED and Mojosari duck= MOD) was investigated by using polyacrilamide gel electrophoresis (PAGE). The result showed that four blood protein loci (Pre-albumin, Albumin, Transferrin and Post-transferrin) and three egg white loci (Ovalbumin, Ovoglobulin and Conalbumin) were found to be polymorphic in three breeds of local ducks. There was no difference on blood and egg white protein polyimorphism. The average value of heterozygosity on three breeds of local ducks had a genetic potential to determine the controlled mating system and selection to obtain pure line. The closest phylogenetic relationship among the three breeds of local ducks occurred between MAD and TED.
