The present article reports on pollen embryogenesis resulting in haploid plants in 14 different F1 lines of Nicotiana tabacum. The response for pollen embryogenesis was high in cultures where the F1 lines were derived from mutants. Present observations are in agreement with previous reports on Secale cereale where one of the parents is from a mutant MII. These observations indicate that plant genotype is the main factor for differences in the induction of pollen embryogenesis.
