Genetic polymorphism of egg yolk and egg white proteins was studied in Japanese quail using the meat lines 08-S3 and 09-K3 of F10 generation and O8-S5 and 09-K5 of F11 generation. A group of 154 birds of each line was tested by starch gel electrophoresis. In both the tested lines of F10 generation, genotypes were found in 33.3%, genotypes BB in 63.3% and genotypes AA in 3.4% of birds. Only one combination of genotypes AB was determined in albumin polymorphism in all of the F11 generation samples (meat lines 08-S5 and 09-K5). In the transferrin system, the distribution of genotypes AB (n=6), genotypes BB (n=4) and genotypes BC (n=22) was observed in F10 generation (meat lines 08-S5 and 09-K5). In each sample analysed of the F11 generation was detected monomorphous genetic combination of genotypes BC. Three genotypic combinations were found in the locus of ovoglobulins G2 in egg white (lines 08-S5 and 09-K5) of F10 generation genotzpe AA }n-!, genotzpe AB }n-& and genotzpe BB }n-@@. In F!! generation: genotypes AB a BB of G2 ovoglobulins were detected. At the same time, genotypes AA and AB of ovoglobulins G3 in egg white were found both in F10 and F11 generations of Japanese quail meat lines
