Summary For the wheat yield, the most impede factor is the climatic conditions during the maturity in the west Japan. When it goes on raining for long time, the wheat is remarkably damaged, especially, owing to the germination on the head. Some experiments were performed on the characters of grain and flour of the rain damaged materials. When the wheat was germinated on the field by the rainy weather, the characters of its grain and flour were deteriorated according to the extent of germination, but the degree of the deterioration was not so heavy as the appearaces of the kernels. In the laboratory milling tests, the germinated wheat in amounts as small as 5 and 1O percent had no appreciable effect upon the milling process. The percentage of steaight flour was higher in the superior wheat varieties, even when they were damaged by the rainy weather, than in the inferior varieties. The materials which were germinated for 3 days on the field, resulted in no appreciable effect upon the baking value. Not only is the percentage of ear garminated kernels important, but also the extent of the sprouting, for the wheat grading.
