• The dominant gene conferring mildew resistance has been transferred from the diploid wild species, Avena prostrata (2n=2X=14) into the cultivated oat A. sativa cv. Sun II (2n=6X=42). The Cw 57 genotype of A. longiglumis has the effect of increasing homoeologous chromosome pairing and can be successfully used to induce upsets the control of chromosome pairing in A. sativa. The possible recombinant lines Av3678/12/40 and Av3945/7/2 were selected at an early stage of breeding programme. The confirmation of desirable recombination was carried out by crossing the disomic addition line and the ditelocentric IX line with the mildew resistant lines. The use of the chromosome substitution line as a source genotype in the crossing programme reduced the amout of screening required compared with the addition line.
