Description and elimination of linkage drag in plant breeding: an overview article

Article in Press

Introducing a gene from a donor parent to enhance a cultivar for a certain attribute is one of the objectives of plant breeding. One possible application for wild germplasm is as a source of resistance to disease. The breeder also wants to avoid introducing any more wild germplasm genes that could lower the cultivar's agronomic fitness. One way to introduce a particular gene into plants is through the backcross method of...
