Abstract
The C-banding technique was improved and all 21 chromosomes of two cultivars of common wheat, Triticum aestivum L, were successfully identified. The improved C-banding constantly differentiated a band or bands in all of the wheat chromosomes except 1A : Chromosomes 3D, 4D, 5D, and 6D, which bear no band by N-banding, showed distinctive banding patterns. The other banded chromosomes had banding patterns similar to those differentiated by N-banding. The C-band patterns comprised the bands by N-banding and, in some chromosomes, C-banding specific ones. The two common wheat cultivars showed similar C-banded karyotypes with minor variations.
