• 1) Since 1929 linkage studies were begun in order to get a fundamental knowledge to the genetics in einkorn-wheats, <I>Triticum aegilopoides</I> var. <I>boeoticum</I> and <I>T. monococcum</I> var. <I>vulgare</I>. The former species is assumed to be the standard type of the latter. The F<SUB>1</SUB> hybrids showed in most cases <I>aegilopoides</I>- or nearly <I>aegilopoides</I>-characters.<BR>2) A linkage group involving 3 genes is established.<BR><I>sca</I><SUB>1</SUB> (<I>scabra</I>)....One of the duplicate genes for pubescent leaf-blades. The phenotypes corresponding to the normal alleles of <I>sca</I><SUB>1</SUB> and <I>sca</I><SUB>2</SUB> are apparently different (Fig. 1). The gene is recessive to its normal allele+ of <I>T. aegilopoides</I>.<BR><I>gla</I><SUB>1</SUB> (<I>glabrescens</I>)....One of the duplicate genes for hairiness of the rachis (Fig. 2). Recessive to its normal allele+.<BR><I>his</I> (<I>hispidulus</I>)....A recessive gene for hairy nodes (Fig. 3). The normal allele+ of the gene is so far completely linked with a gene for pubescence on sheaths.<BR>3) The linkage relationship is shown in Fig. 4.
