Investigation Of Seed Yield And Quality Traits Of Some Soybean Genotypes Using A Biplot Technique In Çukurova, Turkey

Abstract

This research was carried out in Cukurova, Turkey, in the 2018 and 2019 growing seasons to investigate seed yield and quality characteristics, genotype, genotype × environment interactions (GGE), and the relationships between the characteristics and environment examined by multi-featured GGE Biplot analysis in 11 soybean genotypes. According to the results of the combined analysis of variance, the interaction of environment, genotype and environment × genotype was significant (p < 0.05) in all examined traits. According to the average results of both years, the seed yield of the different genotypes varied between 41.11 and 55.36 kg/ha−1, and the oil, protein, palmitic acid, oleic acid, linoleic acid, and saturated fatty acid contents were 22.49–24.17%, 31.22–37.6%, 10.55–11.68%, 21.43–28.31%, 46.68–53.83%, and 14.45–16.44%, respectively. Genotype explained 86.60% of the total variation of the experiment in the multi-trait biplot. In terms of seed yield, the ‘Atakisi’ variety was the highest, followed by the ‘KA-08-03-1’ line. The ‘KA-08-03-1’ line had the highest protein and linoleic acid contents, whereas the ‘Cinsoy’ variety had the highest palmitic acid and saturated fatty acid contents. In conclusion, the interaction of genotype and the multi-featured biplot analysis method may be sufficient to evaluate cultivar candidates for selection.
