1210 turkey hens from generation 12 (G 1 2) and 737 from generation 13 (G 1 3) of the maternal female strain J-44 were investigated. The male parents of the toms chosen to selection flocks in G 1 2 and G 1 3 were evaluated by means of a selection index including reproductive performance of their female relatives: mothers, sisters and half-sisters. The hens, in turn, were selected taking into account the results of the evaluation of the value in use and breeding value of their mothers according to the SELECT system. It has been found that the used breeding methods aiming at increasing the reproductive traits value in strain J-44 hens turned out to be efficient. The achieved breeding gain amounted to 10.2 of eggs, 5.0% of egg fertility and 3.5% of hatchability from fertile eggs.
