Plant habit and production of secondary metabolites in chamomile plants depend on endogenous and exogenous factors that can be divided into two groups (FRANZ 1982): a) morpho-ontogenetic variability, b) genetic variability or genetic determinateness. The activity of these factors is reflected in biomass production, flower drug production, content and composition of essential oil and some other ...

We used a quantitative genetics approach and estimated broad sense heritability (h2b) of myxospore count and the number of genes involved in myxospore formation to gain a better understanding of how resistance to Myxobolus cerebralis, the parasite responsible for whirling disease, is inherited in rainbow trout Oncorhynchus mykiss. An M. cerebralis-resistant strain of rainbow trout, the German R...
