Evaluation of genotype × environment interactions by graphical methods for grain yield and quality in triticale (X triticosecale Wittmack) advanced lines

The study was carried out in 4 locations (Tekirdağ-Süleymanpaşa, Edirne-Center (Sarayakpınar village), Tekirdağ-Hayrabolu and Kırklareli-Lüleburgaz) with 17 triticale advanced lines and 8 triticale varieties, according to the randomized complete block design with 4 replications, during the 2018-2019 and 2019-2020 growing periods. It was aimed to determine the suitable triticale genotypes for the conditions of the Trakya Region. In the study, since it is difficult to understand and reliably determine the complex genotype × environment interaction (GEI) by general variance analysis, parametric and non-parametric stability analyzes (w_i^2, s_(d_i)^2, b_i, σ_i^2, R^2, 〖CV〗_i, Var.,Wi_g, Wi_f, Wi_u, GAI, S_i^((1)), S_i^((2)), S_i^((3)), S_i^((6)), NP(1), NP(2), NP(3), NP(4)) and graphical methods such as AMMI and GGE-biplot analyzes were used to explain the GEI. Grain yield, plant height, spike length, number of spikelets per spike, plant weight, spike weight, number of grains per spike, grain weight per spike, thousand grain weight, hectolitre weight, harvest index, protein ratio, gluten ratio and Zeleny sedimentation value of the triticale genotypes were evaluated, genotype × environment interactions were found to be statistically significant at the 1% level in all examined traits except harvest index. As a result of the study, when grain yield, yield components and quality characteristics were evaluated together, it was determined that NZFT 17, NZFT 13, NZFT 11, NZFT 23 and NZFT 28 advanced lines, among these genotypes NZFT 11 and NZFT 28 advanced lines were determined to be the most promising lines for breeding studies to be carried out in the region in terms of all stability analyzes.
