摘要: An effective germplasm collection provides genetic variation useful to crop improvement, botanical research, and conservation of plant biodiversity. The USDA National Trifolium currently limits the collection's effectiveness in serving multiple uses. Reflecting historic mandate introduction, is strongly biased toward two major cultivated red white clover species, which make up 56% collection. Although many wild species are present collection, representation poor for that considered gene sources have minor use. objectives this article demonstrate how can be diversified better serve users contribute genus. priorities proposed 1970s, scope was defined as containing all within genus Trifolium. Next, a broad gene-pool model on basis ease interspecific hybridization history Areas were then identified required more accessions represent diversity specific interest or vulnerable erosion extinction. essential step before making any changes establish by curators members Crop Germplasm Committee (CGC). If diverse set stakeholders included process, likely result serves makes significant contribution conserving
