A fertile hexaploid (n = 36) mutant with large fruits, derived by doubling the chromosome number of sterile F1 hybrids of tetraploid X diploid S. nigrum, resembled the hexaploid species S. scabrum in morphological and cytological characteristics. It was crossed reciprocally with S. scabrum. The hybrids obtained were hexaploid, showed 82.9% pollen fertility and resembled the parents in morphology and meiotic chromosome behaviour. It is suggested that S. scabrum developed from a mutant of S. nigrum.
