The U.S. National Plant Germplasm System (NPGS) is collaborative effort to safeguard the genetic diversity of agriculturally important plants. The NPGS is managed by the Agricultural Research Service (ARS), the in-house research agency of the United States Department of Agriculture (USDA). R-MPGIS is the DRMR's system for managing rapeseedmustard germplasm information. The system is web based interactive user-friendly and allows users without any specific training or knowledge of. A feasability study conducted by the U.S. Department of Agriculture, Agricultural Research Service, determined that a centralized computer database should be developed to provide and store detailed information on collection, maintenance, distribution, and use of plant germplasm held by the U.S. National Plant Germplasm System (NPGS).Cited by: 1. The Germplasm Resources Information Network (GRIN) system is effectively being used to monitor information on the world's largest collection at the National Center for Genetic Resources Preservation, Fort Collins and the cooperating institutions within the United States Department of Agriculture (USDA) research system in USA ().
Conservation programs must be justified by their effective use. To ensure active use of germplasm, seed/plant/tissue materials and full information on all accessions should be freely and readily available to a broad segment of scientists and growers. Examples of highly successful use of plant germplasm collections are described. The information needed for germplasm-bank management is the information produced during the acquisition, monitoring, regeneration, and distribution of accessions (Ellis, ). The amount and type of information that is processed for germplasm-bank management depend entirely on the procedures used for these basic operations. The accessions used in this study were 97 diploid S. tuberosum Phureja group accessions from the Colombian Core Collection and 13 diploid accessions from the German germplasm bank. Allelic richness, heterozygosity, population differentiation (F statistics) and population allocation by means of Bayesian modeling analyses were performed. Information retrieval is the process through which a computer system can respond to a user's query for text-based information on a specific topic. IR was one of the first and remains one of the most important problems in the domain of natural language processing (NLP).

In this way, the application programs of the search systems are not directly affected by the modification of schema in the genetic resource database. The web retrieval database has been constructed by joining many tables in the genetic resources database.
