THE PAIRING OF AN ALIEN CHROMOSOME WITH HOMOEOLOGOUS CHROMOSOMES OF WHEAT

Abstract
The homoeology of chromosome A of Triticum umbellulatum has been determined by studying its pairing relationships with wheat telocentrics in hybrids having the chromosome constitution of 20 wheat chromosomes + one wheat telocentric chromosome + seven Triticum speltoides chromosomes + chromosome A. It has been found to be homoeologous to the group-6 chromosomes of wheat.
