Double-pair mating

Double-pair mating (DPM) is a mating (crossing) design used in plant breeding.

1 a connected variant of DPM is shown.

DPM is an efficient mating design in balanced breeding programmes, where equal contribution from each breeding population member is desired.

DPM allows to efficiently utilise positive assortative mating for more efficient use of the breeding population members for deployment to seed orchards.

[2] In comparison with single pair mating, DPM has the advantages that the genes from the individual are transmitted to next generation even if one of the crosses fails; that safer estimates of breeding values of the parents get possible (useful for seed orchards, where tested trees are preferred); and that genes from different ancestors have a better chance to combine.
