Genetic analysis of the cross between the self-fertile Nicotiana Langsdorffii and the self-sterile N. Sanderae

, : Genetic analysis of the cross between the self-fertile Nicotiana Langsdorffii and the self-sterile N. Sanderae. J. Genet, 30: 79-100

The colour factors were mainly studied and the following have been identified: c a single recessive gene causing the absence of anthocyanin and related pigments is present in some Sanderae lines. All other Sanderae lines and those of Langsdorffii are CC. A single factor i inhibits the development of anthocyanin on the upper surface of the petals and produces the ivory flower colour.
