Genotype by environment interaction for main winter triticale varieties characteristics at two levels of technology using additive main effects and multiplicative interaction model

Abstract The aim of this study was to assess genotype by environment interaction for grain yield, plant height and thousand-grain weight in winter triticale cultivars the additive main effects multiplicative (AMMI) model. comprised ten varieties i.e.: Algoso, Baltiko, Grenado, Magnat, Moderato, Pawo, Todan, Trimester, Trismart Witon. Field trials were performed at seven locations three years (21 environments) a randomized complete block design, with two replicates levels cultivation technology (standard – A1 intensive A2). experiments carried out as part Post Registration Variety Trials Wielkopolska region. AMMI analyses revealed significant environmental well respect all observed traits both intensity. Baltiko Trimester are recommended further inclusion breeding programs because their stability good average values traits.
