Özet

This study was conducted to determine grain micro (Zn, Fe, B, Cd, Cr, Cu, Mn, Ni, Pb) and macro (K, Mg, P, S, Ca, Na) elements of 164 Turkish sorghum landraces and cultivars. Sorghum grains were sown in incomplete blocks design in Kayseri in 2016. Correlation and genotype-trait (GT) biplot analyses were used to identify correlations among the traits and to identify the prominent genotypes. The highest positive correlations were observed among the micro elements of Fe, Zn, and Mn and between the macro elements of Mg and P and between K and Ca. The GT biplot graph generated for macro elements was able to explain 66.3% of total variation and the graph for micro elements explained 82.2% of total variation. Based on GT biplot analysis, 8 genotypes were selected for macro elements and 14 genotypes were selected for micro elements. Present findings clearly revealed that GT biplot analysis could reliably be used in selection of prominent genotypes.
