Abstract
Genotypic control exercised by B chromosomes affects the mean chiasma frequency in pollen mother cells of rye. By using interchange to identify particular chromosomes it is established that B chromosomes affect chiasma formation in different chromosomes to varying degrees. That genotypic control is chromosome-specific signifies that variation in the amount of recombination may be adjusted independently among different gene complexes within the chromosome complement.
