- Objective: To study the genetic problems of powdery mildew resistance gene in tobacco. Method: after tobacco powdery mildew resistant variety and susceptible variety provided by a greenhouse during May 2015~ May 2016 were selected as the research object, to build a genetic model, genetic laws of resistance gene to tobacco powdery mildew were observed by adopting segregation analysis method. Results: genetics of resistance to tobacco powdery mildew was controlled by recessive genes; compatibility test showed that model E-0 was the optimal model, i.e. genetics of resistance to powdery mildew was controlled by 2 pairs of genes, which respectively were additive-dominant-epistatic major gene and its polygene; the heritability of B1 generation major gene and polygene was 88.6% and 0.0% separately, while the one of F2 generation major gene was 84.5% and 0.0% respectively. Conclusion: pay attention to the selection of disease-resistant materials, interaction effect between genes and environmental factor in practice.
