Abstract
THE sudden appearance of fatuoids, that is, forms resembling the wild oat Avena fatua, in varieties of the cultivated oat A. sativa, has for many years attracted much attention both by its genetic interest and agricultural importance. The opinion has been widely held that they originate through natural crossing between A. sativa and A. fatua, but in recent years they have been more generally regarded as simple loss mutations from A. sativa. The heterozygous form, which is intermediate between the normal and the fully developed fatuoid, usually appears first, and in nearly all cases previously recorded these heterozygotes segregate normals, heterozygotes, and fatuoids in a ratio of approximately 1: 2: 1.
