1. In this study, the author have investigated the relation between the distance of cultivation and frequency of natural crossing of a variety of naked barley in Jpan, namely var. violaceum Keck. with the varieties of naked barley in Jpan, namely Akashinriki and Osakayakko No.52 at Settu Experimental Farm, Kyoto University. 2. The iodine reaction, which is based on the phenomenon of xenia between waxy and nonwaxy characters, on the starch of endosperms of waxy barley, was used as the determination of natural crossing. 3. The percentage of natural crossing in the variety of naked barley in Jpan was lower than that of wheat, and it was 0.061% in the case of mixed cultivation. The phenomenon of natural crossing was not noticed in the case of alternative cultivation, which was over four feet apart between rows in the field.
