Combining ability of varieties and lines of spring durum wheat for productivity elements and quality of gluten

Abstract. The purpose. research is aimed at studying the combinational ability and possibility of transmitting productivity elements quality from Italian Russian sources in order to improve gluten spring durum wheat varieties Siberian ecotype. Metods. In 2020 2021years on basis breeding laboratory “Omsk ASC”, system incomplete topcrosses were studied Zhemchuzhina Sibiri, Omskiy izumrud, korall, Hordeiforme 10-33-3, 11-76-3, Taganrog 3 lines. Material for was evaluated by SDS-sedimentation (SDS), index (IG). Principal component analysis carried out using R package version 4.1.2. Results. genetic control traits: IG, SDS, grain mass main spike, number grains plant dominated additive-dominant system. hybrids F1, according signs productivity, a heterozic effect. Of all traits studied, screening will be effective grains. It advisable carry same time gluten. involvement lines process additionally requires yield properties. Scientific novelty. combinative crossing has been studied. problem ecological changes IG identified, which entails additional research.
