Theory for identification and use of exotic germplasm in maize breeding programs.
1984
Dudley J.W.
Methods of identifying maize (Zea Mays L.)inbred lines or populations which contain new alleles governing quantitative traits are presented. A basic assumption is that the highest concentration of favorable alleles is in the best hybrid available for be particularly useful for applied pedigree breeding programs. The method for identifying populations should be useful for screening populations of exotic germplasm. Once a line of population carrying unique alleles is identified, methods of adding the unique alleles to existing germplasm are needed. Computer simulation studies suggested that when one parent had more loci with favorable alleles than the other, backcrossing at least once to the parent with the larger number of favorable alleles prior to selfing or selecting would be advantageous.
