Genomic dosage effects on heterosis in triploid maize.

Proceedings of the National Academy of Sciences of the United States of America - 12 Feb 2013

Yao Hong, Dogra Gray Anjali, Auger Donald L, Birchler James A

Abstract excerpt

The genetic basis of hybrid vigor or heterosis has been debated for more than a century. A popular hypothesis to explain this phenomenon is that there are different slightly deleterious recessive homozygous alleles in the two parents and that these alleles are complemented in the hybrid so that the biomass and fertility exceed both parents. To address the complementation hypothesis in a direct manner, heterosis...
