title: [Karyotype of Nicotiana tabacum L. artificial haploids].
abstract: Twenty-five platelets obtained by culturing anthers of Nicotiana tabacum L. var. "Wisconsin 38" are haploids (22) or mixoploids (3). Numerous aneuhaploid cells were observed in 15 haploid plants (n = 18, 20, 22, 23, 25, 26, 28). Such a chromosomic variability careful caryological studies of haploid plants before these are used in genetic work.
