Somatic deleterious mutation rate in a woody plant: estimation from phenotypic data.

abstract：:Theory presented in a previous paper has been used to provide a description of the responses expected from selection in two or more generations of a selfing series. Optimum two-stages and multi-stage selection programmes are described, for a limited set of circumstances, and compared with the single-stage designs desc...
