C-bands in the amphiplasty in two interspecific F1 hybrids of Crepis.

Abstract

In the interspecific F1 hybrids of Crepis, C-banding patterns under the condition of amphiplasty were studied. In each hybrid of C. capillaris .times. C. dioscoridis, C. capillaris .times. C. vesicaria and its reciprocal cross, C-banding patterns of individual chromosomes of the hybrids were similar to those of the parents, and were unchanged in the F1 hybrids and in the condition of amphiplasty. The differential and neutral amphiplasties apparently do not give rise to the material change of chromosomes.
