Abstract
Nodding of barley spikes is a useful trait that decreases weathering damage. Peduncle curvature, along with the curvature of spike itself, determines the nodding of spikes. A major quantitative trait locus (QTL) for spike nodding as a result of peduncle curvature was previously mapped on barley chromosome 7(5H) using Steptoe × Morex doubled haploid mapping population. In the present study, spike nodding trait of Steptoe was successfully transferred into Morex background using RFLP markers, and a series of near isogenic lines were developed. Analysis of near isogenic lines located the QTL in a 43 cM interval flanked by ABG473-R3226 markers. A near isogenic line (H18) that contains up to 70 cM of Steptoe chromosome 7 was studied under field conditions. Kernel brightness and wort color and wort clarity properties were improved in HI8 compared to recipient cultivar Morex. However, yield of HI 8 was somewhat lower than that of Morex. A more detailed study of the QTL region, especially for grain yield, is required before the use of this locus in malting barley breeding programs.
