Abstract:

This research was carried out with four cultivars (Lucilla, Rumeli, Glosa and Esperia) and 28 advanced bread wheat lines to determine the yield and quality components in a randomized complete block design with four replications during 2016-2017 and 2017-2018 growing seasons under Kırklareli (Lüleburgaz) ecological conditions. According to the two-year results, grain yield 391-641.2 kg/da, plant height 75.3-120.6 cm, spike length 8.01-12.06 cm, number of spikelets per spike of 14.5-23.4, number of grains per spike of 31.8-62.6, grain weight per spike of 0.87-2.48 g, protein content of 14.3-18%, gluten content of 30.6-40, zeleny sedimentation 53.2-81 ml, thousand kernel weight 28.6-43.3 g, test weight of 72.7-80 kg. Principal component 1 (32.3%) and PC2 (29.3%) analysis explained the 61.6% of the total variation. According to the results of biplot analysis, it was determined that a positive correlation with grain yield, test weight, and a negative correlation with protein ratio, gluten ratio and zeleny sedimentation characteristics. In terms of grain yield, Lucilla, Glosa, G12 and G22 genotypes, with regard to quality components (protein ratio, gluten ratio and zeleny sedimentation) G27 and G26 genotypes were determined to be promising.
