abstract
Crop collections important to the Southern Region have been supported since 1949 through a joint partnership, designated asthe Multistate Research Project S-009, between the USDA-Agricultural Research Service (USDA-ARS) and the SouthernState Agricultural Experiment Stations (SSAES). For years, S-009 has served as a major repository within the NPGS. Itsactivities have markedly improved crop technology in the U.S. and abroad, through acquisition, conservation, characterization,and distribution of plant genetic resources and associated information for use in scientific research, education, and cropimprovement programs in the U.S.This project is one of four regionally-based multistate projects, cooperating with USDA, ARS Units at each location, chargedwith the acquisition, characterization, maintenance, evaluation, documentation, and distribution of agronomic and horticulturalcrops in the U.S. Crops are divided among the four projects to prevent duplication of effort.Curators often complain that the time and effort they have to spent on the conservation, classification and propagation. As a user breederandgeneticist, we can help on a subset of those useful lines to collect data and produce more seeds to decrease some burden for curators.For a subset of useful wheat germplasm lines, we will conduct association analyses for resistance to rusts, wheat streak mosaic virual, greenbug, hessian fly, wheat curl mite and yield, yield components, and somemajor chracteristics for end-use quality. Single nucleotide polymorphisms (SNPs) linked to these important traits will be designed and information will be integrated into the GRIN-Global database and shared with many other users, mainly plant breeders andgeneticists.The plant genetic resources are the base of new germplasm adn cultivar release, which are more adapted to teh changing environments and profitable to producers adn farmers to feed the world with 9 billion by 2050.
