• The genetic analysis on dwarfness of 14 accessions of wild oats, Avena fatua was carried out. They are ecotypes adapted to the man-made habitats of barley and wheat fields as a weed in East Asia. The crosses between the dwarfaccessions and the cultivated oats ′Kanota′ were made to obtain the F1 and F2 hybrids. In order to clarify the genic segregation on plant height, the frequency distribution was studied in the F2 populations of all the cross combinations. Of 14 dwarf accessions studied, 7 were controlled by a dominant gene, and 3 by a recessive gene. Two accessions showed digenic inheritance, whereas an accession (No. 288) showed polygenic inheritance and another accession (No. 342) was controlled by a incomplete dominant gene. The dwarfness in the 14 accessions was controlled by all kinds of the major genes except No. 288. Their allelic relationship is not known yet, except for the recessive gene in 3 accessions. The gene No. 812 is allelic to that of No. 169 but not to that of No. 153.
