The objective of this paper was to estimate phenotypic and genetic correlations in order to improve existing wheat quality breeding methodology in early generations. For this purpose, one-year trial with population of 143 recombinant inbred lines from crossing combination Bezostaja/Klara was carried out on Osijek and Slavonski Brod locations in 2008/09 year. Among analyzed traits (grain protein content, wet gluten content, gluten index, mid-line peak time -MPT, mid-line peak height -MPH and mid-line tail width -MTW) consistent positive phenotypic and genetic pattern of correlations was found between grain protein content and wet gluten content, negative between gluten index with grain protein content and wet gluten content, and positive between grain protein content and wet gluten content with MPT and MPH. Conformity of the phenotypic and genetic correlations was confirmed by Mantel test on both locations (for Osijek r=0.81** and for Slavonski Brod r=0.88**).
