Summary
The advisable number of backcrosses is derived for a population in which the proportion of plants carrying no unintentionally introduced alleles does not exceed a specified value. The advice is based on a number of explicitly mentioned assumptions. As could be expected, the number of groups of homologous chromosomes is a very important parameter. From the results it is concluded that breeders are apt to keep the number of backcrosses too low as far as the replacement of unobserved, unintentionally introduced alleles is concerned.
