Influence of genetic variation of oaks as forage substrate on the fitness components of Tortrix viridana L.
[Free Full Text (pdf)]
The article is focused on the study of influence of genetic variation in DNA (RAPD-PCR, primer OPA 14) of oaks (Quercus pubescens L. and Q. petraea L.) on the variation of some fitness-linked traits in different genotype classes of the Tortrix viridana adults. The results show that the leafroller individuals from the same genotype class may possess the maximum fitness (fecundity and body size components) on the trees of one genotype class and the minimum fitness on the trees of another genotype class. The interaction of the «oak genotype» – «leafroller genotype» factors results in rise of the ties which are expressed in statistically reliable associations between the leafroller and oak genotype classes. The results are discussed from the point of view of the newly developed field of community or ecosystem genetics.
Key words: ecosystem genetics, gene-to-gene interaction
