They are often influenced by environmental factors and show a high genotype-environment interaction. Thus, determination of the number, locations, and ef- fects of these polygenes is desired for obtaining optimal genotypes in breeding practice. To detect QTLs associated with wheat yield, such as grain yield, spike length, grains per spike, spikelets per spike, compactness, fertile spikelets per spike, 1000-grain weight, and grain diameter a set of 168 doubled haploid (DH) lines derived fro
