Abstract

The studies were carried out in 2016 - 2018 on the experimental field of Samara Research Institute of Agriculture in order to identify samples of soft winter wheat with a complex of characteristics: winter hardiness, productivity, resistance to leaf rust and grain quality for usage as initial selection material. The research material consisted of 150 samples of soft winter wheat from 13 countries. The forecrop was bare fallow. The record area of the plots was 10 m2. The repetition was threefold. The sources of winter hardiness were identified: Byrd, CO 07W245, W 95-091 (CIMMIT) with an estimate of overwintering of 8 points, versus 7. 4 points of Biryuza standard variety (Russia); sources of resistance to leaf rust (type of reaction to damage 0, degree of damage 0%, standard 4 and (60%): Byrd, CO 07W245, W 95-091 / AKRON, OKO 07214 (CIMMIT); yield source - Byrd (8, 36 t / ha); source of 1000 grain mass - W 95-091 / AKRON (47.7 g); source of the number of grains in an ear - W 95-091 / AKRON (46.4 pcs); sources of grain mass per ear - W 95-091 / AKRON (2.28 g), OKO 07214 (2.30 g); source of falling number: Byrd (463 s), CO 07W245 (413 s), OKO 07214 (406 s); sources of protein mass fraction in grain: CO 07W245 ( 15.0%), W 95-091 / AKRON (15.5%), OKO 07214 (16.0%); source of rheological and baking properties of dough - OKO 07214 (dough dilution of 50 Farinograph units, valorimetric assessment of 76 valorimeter units, bread volume of 865 ml, bread rating - 4.4 points).
