Abstract
Single chromosomes from Aegilops triuncialis L. (2n = 28, CCCuCu), Ae. sharonensis Eig (2n = 14, S1S1), and Ae. longissima S. &M. (2n = 14, S1S1) were added respectively to common wheat Triticum aestivum L. cv. 'Selkirk' (2n = 42, AABBDD) in monosomic condition and confirmed to have a gametocidal action on common wheat gametes lacking the Agilops chromosome. Three double monosomic addition lines, which had two of the three Aegilops chromosomes, were produced from the monosomic addition lines, and relationships among the three Aegilops chromosomes were studied. The Aegilops chromosomes did not pair with one another in the double monosomic addition lines. In the progeny of the double monosomic addition lines with the triuncialis and sharonensis chromosomes or with the triuncialis and longissima chromosomes, both Aegilops chromosomes were almost always transmitted through male and female gametes. In the progeny of the double monosomic addition line with the sharonensis and longissima chromosomes, only the longissima chromosome was preferentially transmitted through male and female gametes. Thus, the three Aegilops chromosomes were proved to be different from one another in the gametocidal action in common wheat.
