1) The present report deals with the varietal difference on the elongation of the subcrown internode among the representative varieties of barley and wheat in Japan. 2) Seedlings were grown in seeding boxes in which seeds were placed at 3 cm and 6 cm depth under the soil surface. The measurement of the length of the subcrown internode was performed at the stage when the position of the crown had been fixed. 3) All varieties are able to be classified into five classes with respect to the length of the subcrown internode. 4) It is clear that there exists a varietal difference as well as a group difference about the length of the sbcrown internode, by which the position of the crown is determined. 5) Correlation were scarcely found between the other characteristics of a variety, especially cold resistance about which the other workers found it, and the position of the crown. 6) It was discussed that the elongation of the subcrown internode is of much significance on barley and wheat cultures. Further, it was asserted that the method of selection of varieties suited for barley and wheat cultures using modern machines, e. g. drill seeder, should be studied from the point of view above mentioned.
