The influence of 1BL.1RS translocation on technological quality of winter wheat

Abstract

The present paper deals with 1BL.1RS translocation and its influence on some technological parameters of winter wheat quality. Fourteen cultivars created in Yugoslavia which possess this translocation were compared to the same number of commercial cultivars without translocation. Cultivars with 1BL.1RS had higher values of loaf volume, crumb value, content of protein and content of maltose in the flour. Genotypes without the mentioned translocation appeared to have had an advantage over the content of wet gluten and sedimentation value (Zeleny). Path- coefficient analysis for genotypes without the mentioned translocation, demonstrated that the highest direct positive effect on loaf volume had sedimentation value (by Zeleny). In cultivars with 1BL. 1RS none of the studied direct effects were significant. This group of cultivars had a positive and stronger dependence of loaf volume from the content of wet gluten, which was the opposite of the group of cultivars without 1BL. 1RS, which points out the changes in relations between indirect and direct parameters of technological quality. The content of gluten and its changed nature, appear as first limiting factor in determination of technological quality of bread in cultivars with 1BL. 1RS, which points out that in future breeding for high technological quality special attention must be paid to this parameter.
