EFFECT OF DIFFERENT ENVIRONMENTAL CONDITIONS ON WHEAT YIELD AND QUALITY TRAITS

Stability of quality parameters in bread wheat is becoming an important requirement for the milling and baking industries. By conducting multilocation trials wheat breeders are able to select genotypes well adapted to a wide range of environments. The objective of this study was to evaluate grain yield and quality traits of new promising breeding lines from Bc Institute Zagreb in different environments. Botinec (calcaric alluvial soil) and Rugvica (semigley soil) were locations with favorable grain yield whereas at Lovas (degraded chernozem soil), better quality was achieved by all tested genotypes. Several breeding lines performed well regarding grain yield as well as quality traits in comparison with standard cultivars. Due to significantly higher grain yield compared to all other genotypes, breeding line Bc9362 can be pointed out as the most promising for commercial production in a broad range of environments, whereas Bc5204 and Bc5167 had most favorable quality traits (protein content, Zeleny sedimentation value and water absorption).
