Adaptability and stability of new spring triticale varieties and lines

Purpose and objectives. The purpose was to evaluate the adaptability stability of spring triticale varieties breeding lines for yield expression valuable economic characteristics in environmental trials identify best genotypes with a set features.
 Materials methods. We studied 13 (2020–2021) two different agroclimatic environments (Eastern Forest-Steppe [PPI] transitional zone from forest-steppe steppe [UESPP]). experimental plots 2 m2 three replications were arranged series. field assessments performed accordance methods qualification examination plant varieties. parameters determined by AV Kilchevskiy PV Khotylyova’s method.
 Results discussion. assessed features identified. A high capacity (6.85–7.44 t/ha) plasticity (bi 1.34−1.82) intrinsic Darkkhliba Kharkivskyi, Svoboda Kharkivska, YATKH 23-19, 29-19, 40-19, which indicates their ability effectively fulfill performance potentials under favorable conditions. Kripost Kharkiv, Opora Kharkivska found be most adaptable changes These can recommended cultivation growing conditions throughout Ukraine wide range producers.
