Herds of new plant type of pigs of Yorkshire breed are created in the amount of 20 boars and 204 sows in 3 basic pedigree husbandries. It is determined that boars and sows of created type (live weight - 243,6 and 233,2 kg, carcass length - 162 and 161 cm, correspondingly), and sows on multiple pregnancy rate (12,8 piglets), litter weight in 35 days (128,6 kg) surpass elite class requirements and goal standard. The absence of stress-resistant allele n in ryanodine receptor Ryr-1 was determined on the results of molecular gene diagnostics (PCR-RFLP), showing high level of this breed's resistance to stresses. Besides there was a high (up to 0,9) Q allele frequency - insulin like growth factor -2 (IGF-2), that shows genetic determination of meat and fattening performance of local population of Yorkshire pigs
