How Much Genetic Variance will be Reduced Through Clonal Selection?

Clonal selection is defined here as vegetative propagation of selected clones. Clonal selection offers maximum genetic gain and maintenance of pure lines. Recently narrow genetic base has worried people working with clonal selection. The reduced genetic variance among selected clones can be expressed as Vg' = Vg(1.0 - i h 2 (i c)) where Vg is the original genetic variance before selection, i is the selection differential in standard deviation, h^2 is heritability and c is the truncation point in standard deviation. Additional keywords: Phenotypic variance, pure line selection.
