Abstract :Tolerance to biotic and abiotic stress factors is an important issue in wheat breeding studies. Rye translocation is an important genetic resource used in wheat breeding for tolerance to stress conditions and grain yield. In this study, the rye translocation and Glu-B3b allele, which is one of the Low Molecular Weight Gluten Subunits (LMW-GS), were identified by Polymerase Chain Reaction (PCR) method in the population of 145 recombinant inbreed lines (RILs) developed by crossing Tahirova-2000 and Tosunbey cultivars. It was determined that 85 out of 145 RILs carried the Glu-B3b allele. Statistical differences were analysed between the lines containing rye translocation or not in terms of the grain yield, thousand kernel weight and heading time. Physiologically, it was observed that the 1BL.1RS rye translocation affects the heading time. An increase in root biomass was observed in genotypes carrying the rye translocation. It was determined that the thousand kernel weights of the lines were negatively affected by the rye translocation. These results indicated that the lines in the population can be used as gene resources for wheat breeding program and agronomic researches.Keywords : Wheat, Rye tarnslocation, RILs, Glu-B3b
