In the course of the cytological studies of cereals conducted in this department it was noticed, in a number of cells, that two or more bivalents were interlocked with each other at meiotic metaphase. The percentage of cells containing such interlocked bivalents is unusually high in the speltoid mutants of wheat (Triticum vulgare Host), unbalanced types having 40 or 42 chromosomes with a homozygous deficiency instead of the usual 42, and resembling Triticum Spelta more than T. vulgare.
