Number of crosses and population size for participatory and classical plant breeding

  title={Number of crosses and population size for participatory and classical plant breeding},
  author={John R. Witcombe and Daljit S. Virk},
In the breeding of self-pollinating crops, crossing creates variation upon which selection is exerted. If the value of crosses cannot be predicted then this uncertainty means that many crosses need to be made. However, since there is a limit to the capacity of a breeding programme, more numerous crosses result in each cross having a small population size, fewer progenies in later generations and a lower probability of recovering good genotypes from each cross. Published theory on the optimum… CONTINUE READING
