CHROMOSOME VARIATION IN CALLUS CELLS DERIVED FROM SECALE CEREALE L. WITH AND WITHOUT B-CHROMOSOME

Abstract
Chromosome number was examined in 8 strains of callus cells in S. cereale L. with and without B-chromosome. Variation of chromosome number was small without B-chromosome and was large with B-chromosomes (1, 2 and 4 B-chromosomes). Selective functions might exist in B-chromosome of callus cells in S. cereale L.
