Inbreeding depression and its evolutionary consequences
TL;DR: The evidence that the evolution of breeding systems of animals and plants has been significantly influenced by the occurrence of inbreeding depression is reviewed, and the contemporary genetic theory of inmarriage depression and heterosis and the experimental data concerning the strength of in breeding depression are considered.

Marker-assisted selection: an approach for precision plant breeding in the twenty-first century
TL;DR: An overview of the advantages of MAS and its most widely used applications in plant breeding, providing examples from cereal crops and ways in which the potential of MAS can be realized are suggested.

Molecular Markers and Selection for Complex Traits in Plants: Learning from the Last 20 Years
TL;DR: Key lessons learned from apply- ing markers in plant breeding include the purpose of detecting QTL should be clearly defined before embarking on QTL map- ping and procedures for marker-based selection depend on the number of QTL.
