Abstract
ALLOPOLYPLOIDY has played a vital role in the evolution of plant species useful to man. Hybridisation between related species followed by chromosome doubling has given rise to some of our most important grain, forage and fibre crops. The successful establishment of a sexually reproducing polyploid would, however, depend on the integration of the constituent genomes into a meiotically and, hence, reproductively stable form which could be achieved only by means of a precise diploidising mechanism. In the case of bread-wheat it has been conclusively demonstrated that diploid-like meiotic behaviour is genetically controlled1,2 and there is a strong indication of a similar control in other crop species, for example, hexaploid oats3 and tetraploid cottons4.
