Aim. The aim was to study combinative ability of winter wheat – carriers of wheat-rye translocations by of weight seed from plants to determine their breeding values and model the possibility of valuable generations selection. Methods. Studies were conducted using field, laboratory and mathematical-statistical methods. Results. The highly significant effects of both general combinative ability and specific combinative ability of studied varieties by of weight seed from plants are found out with the disperse analysis. Conclusions. By weight of grains from plants the sources of steady high general and specific combinatve abilities are distinguished: effects general combinatve abilities – Smuhlyanka, Rozkishna; effects specific combinatve abilities – Smuhlyanka / Myronivs’ka rann’ostygla, Rozkishna / Myronivs’ka rann’ostygla, Rozkishna / Remeslivna, Remeslivna / Epoha оdeska, Myronivs’ka rann’ostygla / Rozkishna, Kryzhynka / Rozkishna. The mentioned above cultivars are recommended to be involved in hybridization under conditions of Forest-steppe of Ukraine to improve the studied feature.

Keywords: winter wheat, wheat-rye translocations, combinative ability, weight seeds from plant.
