Grain quality of samples of the spring triticale collection (× <i>Triticosecale</i> Wittmack)

Abstract

The results of testing (2018–2019) varieties and lines of the spring triticale collection in the south-east of the Republic of Kazakhstan are presented. The study was conducted on 70 samples of domestic and foreign breeding from around the world: Russia, Ukraine, Belarus, Poland, Moldova, Austria, Canada, Argentina, Mexico. The experiment was carried out according to the methodology of the state variety testing of agricultural crops. To identify sources of economically valuable traits of grain, the following indicators were studied: test weight, flour sedimentation, protein and starch content, and falling number. The most valuable samples were identified as the starting material for creating varieties for animal feed and baking. Sources of high test weight (13 samples), sedimentation (five samples), protein content (six samples), starch (eight samples) were selected as the starting material for breeding on grain quality. Based on the assessment of spring triticale collection samples for protein content, flour sedimentation and falling number, the following varieties were selected for baking: Ukro, Korovai Kharikvsky, Addax, No. 7 (Rovnya x Lotos), MX 107. Due to high starch content (above 60%) the following varieties were selected for animal feed: WANAD, Pollmer 2,1,1, Fahad 8-2*2//PTP, Rubik, L 5635, Mieszko, L-105/08, Siskiyou. A positive relationship between starch content and test weight, and a positive correlation of starch content and falling number was revealed. All samples of varieties of spring triticale in the south-east of Kazakhstan formed grain with high falling number in the range of 192–336 s and were rated as first-class grain.
