Bread wheat is grown under a wide range of environmental conditions where climatic factors combined with agronomicinputs impart diverse effects on plant growth. This research was carried out in an experimental area of the Institute inEdirne, Trakya region (Turkey) to compare the yield, quality and some physiological parameters of wheat genotypes.The research was carried out with 11 genotypes in RCBD with 4 replications during 2012-2013 and 2013-2014 growingseasons. Data on grain yield, days to heading, plant height, 1000-kernels weight, tes t weight, biomass, canopy temperatureand chlorophyll content were examined. According to the results, significant differences among genotypes in terms ofyield, plant height, biomass, chlorophyll content and 1000-kernel weight were found. Genotypes G16-2012 and Tekirdağhad higher grain yield. Tekirdağ had the highes t biomass and Bereket and Selimiye had higher chlorophyll content. Thelowes t canopy temperature was measured in genotypes G19-2012, Bereket, Selimiye and Aldane. The highes t 1000-kernelsweight and tes t weight were determined in cultivar Pehlivan and Selimiye. A positive correlation was determined betweengrain yield with biomass and chlorophyll content. There was a negative correlation between canopy temperatures withgrain yield. Biomass in genotypes negatively correlated with days of heading, plant height, 1000-kernel weight and tes tweight. A negative relationship was also determined between chlorophyll content and canopy temperature. Due to, thepositive relation between grain yield and chlorophyll content and biomass and a negative relation with canopy temperature,physiological parameters could be used in selection in bread wheat for yield potential under rainfed condition.
