Kara R. and A. Akkaya (2023). Genotypic differences for chlorophyll, ash and N contents and their relations with grain yield in Turkish bread wheat landraces. -Genetika, Vol 55, No.1, 177-191. The genetic differences in the landraces are very important for plant breeding. The aim of this study was to determine the genetic differences for chlorophyll, ash and N contents and their relations with grain yield in Turkish bread wheat landraces. There were significant genetic differences for grain yield (GY), ash content of flag leaf at anthesis (AFLAC), ash content of spike at anthesis (ASAC), ash content of flag leaf at maturity (MFLAC), grain ash content (GAC), chlorophyll content at anthesis (ACC), chlorophyll content at early milk maturity (EMCC), chlorophyll content at late milk maturity (LMCC), chlorophyll content at early dough maturity (EDCC), N content of flag leaf at anthesis (FLN) and spike N contents (SN). The grain yield was positively and significantly related with AFLAC, ASAC, MFLAC and ACC, negatively and significantly related with GAC, EDCC and SN, not significantly related with EMCC, LMLC and FLN.
