|Title:||Optimization of a crossing system using mate selection||Contributor(s):||Li, Yongjin (author); Van Der Werf, Julius Herman (author) ; Kinghorn, Brian (author)||Publication Date:||2006||DOI:||10.1051/gse:2005033||Handle Link:||https://hdl.handle.net/1959.11/3145||Abstract:||A simple model based on one single identified quantitative trait locus (QTL) in a two-way crossing system was used to demonstrate the power of mate selection algorithms as a natural means of opportunistic line development for optimization of crossbreeding programs over multiple generations. Mate selection automatically invokes divergent selection in two parental lines for an over-dominant QTL and increased frequency of the favorable allele toward fixation in the sire-line for a fully-dominant QTL. It was concluded that an optimal strategy of line development could be found by mate selection algorithms for a given set of parameters such as genetic model of QTL, breeding objective and initial frequency of the favorable allele in the base populations, etc. The same framework could be used in other scenarios, such as programs involving crossing to exploit breed effects and heterosis. In contrast to classical index selection, this approach to mate selection can optimize long-term responses.||Publication Type:||Journal Article||Source of Publication:||Genetics, Selection, Evolution, 38(2), p. 147-165||Publisher:||EDP Sciences||Place of Publication:||France||ISSN:||0999-193X||Field of Research (FOR):||070201 Animal Breeding||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 184
