The paper assesses the efficiency of using the federsex for marker genes K-k maternal parental form and the final broiler hybrid of the new highly productive cross Smena-9 in production conditions. It was found that two-lined chickens of the maternal parental form SM79 have an advantage over the original lines in reproductive qualities (egg production, hatching eggs, hatching, number of chickens per a laying hen) by 1.23-25.6%. Under optimal conditions for feeding and keeping, 138.5 heads of day-old broilers can be obtained from the autosex maternal parental form. During selection of linear poultry, the following indicators of broilers were improved: livability, live weight, dressed weight, yield of pectoral muscles and reduced feed costs per 1 kg of live weight gain. The meat yield from one parental pair was 314.8 kg. The taste qualities of broth and poultry meat of the Smena-9 cross are high. The sexing accuracy is 99.8%. Poultry of the federsex maternal parental form and the final hybrid - broilers of the new Russian cross Smena-9 has a high genetic potential and can be successfully used in the production of eggs and meat at enterprises of various types.
