We investigated genetic variation of body weight and appearance by trait combination. To maintain high productivity of piglets, the body weight of sow should be kept above 150-160 kg in crossbreeding of 3 races. The trait of its number was transmitted varying with negative results. It is rational to fix the fur colour to the colour of white stripes, in cross-breeding between Jasan pig, Jamo breed pig and white-striped pig. In the cross-breeding of 3 races, the number of its parturition was increased in proportion and was changed according to the body weight of the sow.
