Chromosome numbers are reported for 108 plants from fusion experiments involving haploid tobacco plants respectively v (virescent) and s (sublethal). In somatic hybrids, a chromosome number of 48 was most commonly found, though triploids with 72 and amphitetraploids with 96 and aneuploids were also observed. It is suggested that triploids and tetraploids may have arisen by fusion of more than two protoplasts.
