Abstract
Somatic association of rye chromosomes has been studied by Giemsa banding technique at interphase in wheat-rye addition lines. Telomeres of the rye chromosomes appearing as chromocenters, showed close somatic association in disomic addition lines, but they were distributed at random in double monosomic additions. This demonstrates directly that somatic association of homologues at interphase is even closer in non-dividing nuclei than in metaphase cells, which had been investigated so far. The finding has relevance to the assumption that somatic association phenomena are a prerequisite to the meiotic pairing process.
