Tests of taxonomic and biogeographic predictivity: Resistance to disease and insect pests in wild relatives of cultivated potato
A major justification for taxonomic and biogeographic research is its assumed ability to predict the presence of traits in a group for which the trait has been observed in only a representative subset of the group. Such predictors are regularly used by breeders interested in choosing potential sources of disease and pest resistant germplasm for cultivar improvement, by genebank managers to ...

Cost efficiency of cryopreservation as a long-term conservation method for coffee genetic resources
Coffee (Coffea spp.) is one of the world's most valuable agricultural export commodities produced by small-scale farmers. Its germplasm, which holds useful traits for crop improvement, has traditionally been conserved in field genebanks, which presents many challenges for conservation. New techniques of in vitro and cryopreservation have been developed to improve the long-term conservation of ...

Population structure and genetic diversity of the trinitario cacao (Theobroma cacao L.) from Trinidad and tobago
Population structure of the old Trinitario cacao (Theobroma cacao L.) in Trinidad was evaluated from the 35-microsatellite multilocus profile of 32 relict clones from abandoned cocoa estates in Trinidad (TRD) and 88 Imperial College selections (ICS) clones conserved in the International Cocoa Genebank, Trinidad. Ancestry was derived by comparison to 34 representative genotypes of Criollo, Central ...

Augmenting the pearl millet core collection for enhancing germplasm utilization in crop improvement
Developing a core collection that represents the diversity of entire collection is an efficient approach to enhance the use of germplasm in crop improvement. Core collections are dynamic and need to be revised when additional germplasm and information become available. In the present study, the pearl millet [Pennisetum glaucum (L.) R. Br.] core collection, consisting of 1600 accessions selected ...

Genetic assessment of a mini-core subset developed from the USDA rice genebank
Development of core collections is an effective tool to extensively characterize large germplasm collections, and the use of a mini-core subsampling strategy further increases the effectiveness of genetic diversity analysis at detailed phenotype and molecular levels. We report the formation of a mini-core subset containing 217 entries derived from 1794 core entries representing the genetic ...

Genetic diversity in a core collection established from the main bean genebank in Spain
Common bean (Phaseolus vulgaris L.) is a traditional crop in many Spanish regions. A major collection of Spanish common bean landraces is maintained at the National Genebank in the Center for Plant Genetic Resources (CRF), Alcala de Henares, Madrid, Spain. A core collection including 200 common bean accessions was established from the CRF collection. We sought to analyze the genetic diversity of ...

Introducing Dr. Beatrice Amyotte, Small Fruit Germplasm Development Program
The berry breeding program at the Agriculture and AgriFood Canada (AAFC) Kentville Research and Development Centre in Kentville, Nova Scotia, is now the Small Fruit Germplasm Development Program. The new approach to plant breeding will allow the fruit industry to be more involved in the release of new Canadian varieties of strawberries, raspberries, blackberries and grapes that are developed ...

Crop gene banks are preserving the future of agriculture. But who’s preserving them?
As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate groups vying for control of ...
