Abstract
The discovery that the 21 different chromosomes of common wheat (Triticum aestivum L.) fall into seven homoeologous groups of three (Sears, 1952, 1954) was based primarily on the ability of each tetra-some to compensate for the nullisome of each of the other two chromosomes of the same group. Supporting evidence has come from the finding of Okamoto and Sears (1962) that the pairing in haploids is largely between chromosomes belonging to the same homoeologous group, and from the work of Riley and Kempanna (1963), who found only pairing of homoeologues when increased pairing was induced by the absence of chromosome 5B.
Co-operative investigations of the Crops Research Division, Agricultural Research Service, U.S. Department of Agriculture, and the Field Crops Department, Missouri Agricultural Experiment Station. Journal Series No. 2796 of the Missouri Station. Approved by the Director.
