Abstract

11 Winter triticale genotypes (5 lines and 6 released varieties) were evaluated and classified using Metroglyph analysis according to their grain yield performance and phosphorus uptake under-both dryland and calcareous soil condition in Turkey. All genotypes were grown at a single rate of P (26 kg/ha). The grain yield of the lines and the combined genotypes were found to be significant (p < 0.05). TVD-17 in particular was found to have had the highest total P-uptake (15.62 %) and grain yield (3912 kg/ha). The grain yield, biological yield, P content in grain (%) and total P-uptake (%) averages of the lines were higher than that of the varieties. The results revealed that while TVD-17 appeared in the HGY-HP (high grain yield-high P-uptake) group, Tatlicak 97 variety was in the LGY-LP (low-grain yield-low P-uptake) group.
