Özet:

The study was conducted in the 2011-12 and 2012-13 cultivation seasons, in the Hazro/Diyarbakır ecological conditions, with the aim of researching the productivity and some quality characteristics of 5 species registered in rain-based conditions with 20 bread grain genotypes in the advanced stage of summer development. According to the two-year combined variance analysis results, the differences between genotypes (P<0.05) were statistically significant for all the characteristics studied. In the first year, G21 (392 kg/day) and in the second year, the Genotypes (610 kg/day) were genotypes with the highest yield, while G4, G8 and G5 (G5) were genotypes with the highest yield and the same yield performance in both years, while the Genotypes G19 and G21 were recorded with different yields in both years, despite the highest yield than the average. In the first year, for the G9 thousand and hectoliters, for the G21 genotype one production (TV), for the G3 sedimentation, for the G4 protein, and in the second year, for the G14 genotype one weight, one number, for the G12 sedimentation, for the G15 and G2 thousand weight, the highest performance genotypes were. According to the results of the simple correlation analysis, the number of square meters and one output; positive between the protein ratio and sedimentation; negative and statistically important correlations between the protein ratio and one output. According to the study, the G21 genotype is identified as an hopeful genotype for the registration of varieties because it has superior characteristics for both one-production and quality characteristics, while the detection of varieties with high one-production in grain refining programs has found that the number of refiners in the unit area can be used as a selection criterion.
