Abstract
In the 21st century, to strengthen the international competitiveness of domestically produced common wheat (Triticum aestivum), it is essential to improve the grain quality and develop a unique product that will satisfy the demands of domestic consumers. To achieve these goals, the factors determining the quality of grain from Japanese common wheat cultivars must be characterized (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24). The quality of common wheat grain favored in bread making quality is strongly affected by components of seed storage protein, particularly high-molecular-weight (HMW) glutenin (30). I undertook the study to elucidate the allelic composition of HMW glutenin with the objective of improving the grain quality of Japanese common wheat. In my study, I show that the main factors affecting the Glu-Dlf allele frequency were the intensity of natural selection for winter habit and/or artificial selection for flour hardness. These selection pressures favour wheat quality and good cultivar. It is believed that cultivated common wheat originated in the Middle and Near East and traveled via the Silk Road through China to the Far East Japan, the geographically remote region for common wheat production. During the course of its long journey and its adaptation to diverse local environments, Japanese common wheat has developed a unique composition of glutenin genes and a narrow genetic base
