Technical Abstract: Plant breeding, genetics, and genomics play a critical role in sustainable agriculture specifically in improving crop productivity, quality, and resistance to pests and diseases. The germplasm collections have been treasures of crop genetic resources. Utilization of the collections of wild peanut species has been slow because of the limited breeding and genetic tools available to assist breeders in interspecific introgression of desirable traits into cultivated peanut although a few successful cases were documented such as ‘NemaTAM’ and ‘Tifguard’ with nematode resistance, ‘GPBD 4’ with rust and late leaf spot resistances, and ‘Bailey’ with multiple disease resistances. Peanut molecular genetics and genomics also have demonstrated the potential for transforming peanut breeding and cultivar development through increased integration of marker-assisted breeding. During the past 10 years, since the U.S. Peanut Genome Initiative was launched in 2004 in Atlanta and expanded to global efforts in 2006 in Guangzhou, China, the international peanut community has been working together through coordination of efforts in genome research beginning with molecular marker development, improvement of map resolution and coverage, and development of mapping populations. The peanut genome sequencing project was launched in 2012 by the Peanut Genome Consortium to sequence both wild ancestors and cultivated peanuts. The collaborative and coordinated efforts since 2004 have contributed to development of large-scale genomic resources and tools in order to effectively tap into germplasm collections. The reference genome sequence and the high density maps will serve well into the future for peanut cultivar development and research. The International peanut conference of AAGB-2014 will be held in Savannah, GA, in November 2014.
