By using aneuploid lines of wheat in the variety Chinese Spring, each of the homoeologous group 1 chromosomes was found to delay ear emergence. More than one gene per chromosome was probably involved, and, because of the delays in ear emergence, at least one of them may be responsible for producing an inhibitor of flowering. The genes interacted with each other and with vernalization and day length. The genes on chromosome 1A were the most potent and 1B the least. The genes on the group 1 chromosomes may be related to the genes for vernalization and day‐length sensitivity found on the homoeologous chromosome 1H of barley. Reciprocal monosomic analyses of three varieties detected allelic variation between homologues of group 1 for ear‐emergence time.
