Grain quality evaluation of modern spring bread wheat varieties from KASIB-22 nursery in the Urals and Western Siberia

Abstract

The evaluation results of the indicators of grain quality and yield of 44 varieties and lines of spring bred wheat developed in 14 scientific and breeding institutions of Russia and Kazakhstan (Kazakhstan-Siberian nursery of spring bread wheat - KASIB-22) are presented. Test points in the regions of Western Siberia and the Urals: Omsk (Omsk SAU), Novosibirsk (Siberian research institute of pant production and breeding), Kurgan (Ural ARC), Chelyabinsk (Chelyabinsk ARI). The study noted the greatest range of variation in the characteristics of protein and gluten content in grain (14.2–17.9% and 28.0–37.0%), falling number (295–393 sec), and yield (2.19–4.09 t/ha). The studied modern varieties of spring bread wheat KASIB-22 had high rates of protein, gluten (14.2–17.9%, and 28.0–37.9%, respectively), gluten index (91.8–95.4%), sedimentation (48.9–55.8 ml), and falling number (295–393 sec), which indicates a low amylolytic activity of enzymes, high nutritional value, and good baking properties of grain. The breeding value for improving the grain quality traits of the KASIB-22 nursery samples was revealed: Line 435/12 (North-Kazakhstan Agricultural Experimental Station), Lutescens 1364, Lutescens 1356 (Siberian research institute of pant production and breeding), Agronomicheskaya 5 (Omsk SAU), Lutescens 82/09-7, Lutescens 71/10-4 (Omsk ARC), Chelyabinka (Chelyabinsk ARI), Lutescens 1462, Lutescens 1486, Line 1616ae14 (Samara ARI).
