Barthii是作物改良中几种重要性状的来源，包括抗虫性、耐旱性、幼苗活力、杂草竞争、对有毒土壤的耐受性、谷物品质和谷物产量。为了扩大水稻分子遗传学进展的影响，需要在亚洲水稻的背景下为转译基因组学工作开发水稻种子储备（O。适应美国的栽培品种。这个快速项目将产生急需的基因型遗传股票，包括回交自交系（BILs）和先进的回交（ABC）定位群体使用两个O。glaberrima和O. barthii作为供体亲本与美国水稻品种LaGrue和M-202杂交。 这些种子储备也将作为水稻育种者的一种资源，将O. glaberrima和O.巴尔蒂。进入他们先进的育种系。所有种子储备将通过USDA-ARS遗传储备-稻属（GSOR）保藏中心（Stuttgart，AR）分发。 所有基因型信息都将通过AGI网站（www.genome.arizona.edu）在线提供。 除了所产生的资源的影响，该项目将为博士后研究人员提供培训，他们将在管理合作研究项目的各个方面得到指导。 为了鼓励下一代植物科学家和育种家，该项目将参与戴尔邦珀斯国家水稻研究中心和阿肯色州大学水稻研究和推广中心现有的推广计划。 最后，该项目还将参与亚利桑那大学本科生生物学研究计划（UBRP），该计划与全州社区学院有联系，并为少数民族提供资金。 该项目还将受益于与国际热带农业中心（CIAT）的合作，该中心将利用O。glaberrima和O. barthii在南美水稻栽培品种的背景下。

PI: Georgia C. Eizenga (University of Arkansas/USDA-ARS Dale Bumpers National Rice Research Center) CoPI: Paulino L. Sanchez (University of Arizona)Key Collaborator: Mathias Lorieux [International Center for Tropical Agriculture (CIAT), Colombia]West African cultivated rice (Oryza glaberrima) and its progenitor species, O. barthii, are a source of several traits important in crop improvement including pest resistance, drought tolerance, seedling vigor, weed competition, tolerance to toxic soils, grain quality and grain yield. To expand the impact of the advances being made in rice molecular genetics, rice seed stocks need to be developed for translational genomics efforts in the background of Asian rice (O. sativa) cultivars adapted to the USA. This RAPID project will generate critically needed genotyped genetic stocks that include both backcross inbred lines (BILs) and advanced backcross (ABC) mapping populations using three selected accessions of both O. glaberrima and O. barthii as the donor parent with US rice cultivars LaGrue and M-202. These seed stocks will also serve as a resource for rice breeders to incorporate the abiotic and biotic stress resistance found in O. glaberrima and O. barthii. into their advanced breeding lines. All seed stocks will be distributed through the USDA-ARS Genetic Stocks - Oryza (GSOR) Collection (Stuttgart, AR). All genotypic information will be available on-line through the AGI web site (www.genome.arizona.edu). Beyond the impact of the resources generated, the project will provide training for a post-doctoral researcher who will be mentored in all aspects of managing a collaborative research project. To encourage the next generation of plant scientists and breeders, the project will participate in existing outreach programs at the Dale Bumpers National Rice Research Center and the University of Arkansas Rice Research and Extension Center. Finally, the project will also participate in the University of Arizona Undergraduate Biology Research Program (UBRP) which has links to statewide Community Colleges and targets funds for minorities. The project will also benefit from a collaboration with the International Center for Tropical Agriculture (CIAT) that will develop genetic stocks with O. glaberrima and O. barthii in the background of South American rice cultivars.
