Sažetak
The bread making quality of winter wheat (Triticum aestivum L.) depends on the genotype, nitrogen, environment and their interactions. Among the environmental factors, a special place has nitrogen, since it affects the amount and structure of the grain protein content. The aim of this study was to evaluate the effect of two nitrogen fertilization levels on the mean and the heritability of indirect indicators of quality and rheological properties, and to determine the correlation of traits between the two fertilization levels. Research was conducted on 19 winter wheat genotypes planted in eight environments with 80 kg N/ha and 180 kg N/ha. All the studied traits (except gluten index) recorded a higher values at 180 than at 80 kg N/ha. For all indirect indicators of quality (except falling number) and rheological properties the value of heritability was higher at N180. There was a significant effect of genotype and nitrogen level on all properties due to high correlation among traits between the two fertilization levels. In conclusion, the genotypes adapted to reduced nitrogen fertilization could be selected from germplasm included in existing breeding program conducted at the optimal nitrogen level.
