EVALUATION OF PRODUCTIVE AND QUALITATIVE CHARACTERISTICS OF PROMISING LINES OF SPRING SOFT WHEAT

Abstract

Based on the study of the F7 hybrid progeny in wheat, lines were identified that have donor properties for certain traits: Az × K-5 - for plant height (79 cm) and productive tillering (1.5); Az×K -55 - according to the productivity of the ear (1.31 gr.); KxAz-177 - for coarse grain (39.54 g). The line Az x K-17 was recognized as the best in terms of quality, and the line Az × K -5 stood out in terms of yield. According to the degree of transgression of the grain mass index per ear, a promising combination is the KxAz-177 line, which has the highest index in the F7 generation and is 63.0%. Line AzxK-55 stood out with a positive degree of transgression in terms of cumulative traits. Az x K-17 (18.8; 32.0%), Az x K-5 (17.9; 31.8%) can be distinguished as the best lines in terms of protein and gluten content. According to the IDK, all lines of the hybrid population Karabalyk 90 × Altai reaper of direct and reverse crossing belong to group I, the gluten is good, the lines Az x K-55, Az x K-17, Az x K-5 have a high hardness index.
