A diallel cross is a mating scheme used by plant and animal breeders, as well as geneticists, to investigate the genetic underpinnings of quantitative traits. In a full diallel, all parents are crossed to make hybrids in all possible combinations. Variations include half diallels with and without parents, omitting reciprocal crosses. Full diallels require twice as many crosses and entries in experiments, but allow for testing for maternal and paternal effect… WebDec 22, 2011 · Generally, plant breeders use Griffing’s [10] diallel mating design to identify desirable parents along with their specific cross-combinations and to get the knowledge of genetic effects, estimates of general combining ability (GCA), specific combining ability (SCA) and variance components [11–15].
