The Genetic structure and economic benefits of hen crosses wide–sread in poultry farms of Ukraine(«Borky 117», («Borky–colour» and «Slobodsky–3» and 2 foreingn farms «Lomann Brown», «Dominant Brown D–102») have been conducted. Each line has its own profile according to the marker signs and signify cantly different from the other in freguency of the display of most specific erythrocyte andtigents. Only w 13 of the 32 studied EA found in all lines. Each line has no from one 13 redblood cell antigents, various degree of their genetic differentiativn according to the marker signs as well as various sizes of heterosis for egg production in final hybrids are shown. Imported crosses haven’t shown promised hetevosis in the farms of Ukraine. It has been observed small value of heterozygosis (1,2–2,8 %) in the final hybrifs of foreign crosses that indicate their high sntelligibility to the terms of feeding and keeping. The output lines of «Lomann Brown», and «Dominant Brown D–102» can be used in the design of new high productive crosses, because of their high too egg production ability and in some cases too high masses of eggs. Greater use of domestic breeding crosses is recommended as more adapted w local conditions and feeding.
