Cross-breeding features of influence of genetic and paratypical factors on productive qualities of descendants of male pigs of Belarus meat and large white breeds are established. The stronger influence of the genetic factor on age of achievement of alive weight of 100 kg and a daily average gain on cultivation (Р 0,01 0,001) on the Belarus meat breed, and on large white – on length of a trunk, a thickness of the pork fat, a daily average gain of alive weight on cultivation (Р 0,05) is proved. Paratypical factors make stronger impact on productive qualities of animals of the Belarus meat breed with the raised variability in comparison with the genetic ones. According to results of research on individuals of the Belarus meat breed the genetic factor, in particular in intensity of growth of male pigs was shown on their progeny more strongly in comparison with contemporaries of the large white breeds. Productive qualities of animals of Belarus meat and large white breeds in two adjacent years are resulted. Distinctions in reaction of genotypes on productive qualities on condition of year are shown. Data have shown that on age of achievement of weight of 100 kg among male pigs of large white breed distinctions in parameters between the first and the second year have made 1,0%, on contemporaries of the Belarus meat breed a difference on a similar indicator in the second year has appeared statically authentic at P 0,001 in relation to the first year
