Summary
Genetic parameters for describing the induced continuous variation of self-fertilising plants have been defined in terms of mutation rate per allele and the additive and dominance effects of the genes concerned. Estimation and interpretation of these parameters are discussed.
It is shown that no single generation up to the M3 provides enough statistics to estimate the parameters, unless mutagenic treatment is applied to zygotic cells. As in the case of generations derived from hybridisation between two inbred lines, information on the average degree of dominance and gene association in parental lines can be obtained using these estimates. The mutation rate can be estimated when two parental lines with significantly different phenotypic values are investigated simultaneously.
