Relationships of Grain Yield and Some Quality Parameters with Physiological Parameters in Some Triticale Advanced Lines

This study was carried out to determine the relationships between grain yield and quality traits with some physiological parameters which measured at the heading stage. In this study, 9 triticale advanced lines were grown under rainfed conditions according to randomized complete block design with four replications during the 2014-2015 growing seasons in Diyarbakır and Mardin conditions. The triticale genotypes of 41-ITSN-8022, 41ITSN-8024 and DZ9-06 were found promising in terms of grain yield and quality parameter. Genotypic differences were significant for SPAD meter and leaf area index. It was remarkable the relationship between SPAD and grain weight although the relationships among physiological traits and quality traits changed depend on locations. Especially, the significant relation between LAI and grain yield suggest that physiological traits have potential to use as indirect selection criterion in future triticale breeding. The more related researches are necessary to reach this aim.
