Variety traits
Nicotiana tabacum L.
Heterosis in tobacco is utilized to increase leaf biomass yield and improve the quality characteristics of the raw material. The effect is evaluated by comparing F1 hybrids with mid-parent values or commercial standards.
In the reference 6 varieties crop Tobacco, where this is mentioned in the description.
The manifestation of heterosis in tobacco depends on the genetic distance between parental lines and the type of variety, with the effect typically being more pronounced in Burley tobacco than in Virginia. The significance of heterosis is confirmed by the mathematical superiority of the hybrid over control forms within the framework of analysis of variance.
The use of first-generation hybrids promotes increased productivity and changes in the biochemical composition of the leaf, including nicotine and sugar content. Enhanced yield and general biological resistance of hybrids to stress factors are achieved, among other methods, through cytoplasmic male sterility systems.
