Biogeography of Wild Arachis: Assessing Conservation Status and Setting Future Priorities
plant species are threatened globally, equivalent to some 12.5% of the estimated world flora. Other estimates The conservation status of wild Arachis spp. is not well charactersuggest that 25 to 35% of plant genetic diversity could ized for its maintenance and possible future exploitation for the improvement of cultivated peanut, Arachis hypogaea L. Our objectives be lost in the next 20 yr. Tho...
متن کاملSuccessful crosses between fungal-resistant wild species of Arachis (section Arachis) and Arachis hypogaea
Peanut (Arachis hypogaea) is the fifth most produced oil crop worldwide. Besides lack of water, fungal diseases are the most limiting factors for the crop. Several species of Arachis are resistant to certain pests and diseases. This study aimed to successfully cross the A-genome with B-K-A genome wild species previously selected for fungal disease resistance, but that are still untested. We als...
متن کاملAbundant Microsatellite Diversity and Oil Content in Wild Arachis Species
The peanut (Arachis hypogaea) is an important oil crop. Breeding for high oil content is becoming increasingly important. Wild Arachis species have been reported to harbor genes for many valuable traits that may enable the improvement of cultivated Arachis hypogaea, such as resistance to pests and disease. However, only limited information is available on variation in oil content. In the presen...
متن کاملIdentification of Fungus Resistant Wild Accessions and Interspecific Hybrids of the Genus Arachis
Peanut, Arachis hypogaea L., is a protein-rich species consumed worldwide. A key improvement to peanut culture involves the development of cultivars that resist fungal diseases such as rust, leaf spot and scab. Over three years, we evaluated fungal resistance under field conditions of 43 wild accessions and three interspecific hybrids of the genus Arachis, as well as six A. hypogaea genotypes. ...
متن کاملCharacterization and Transferable Utility of Microsatellite Markers in the Wild and Cultivated Arachis Species
Microsatellite or simple sequence repeat (SSR) is one of the most widely distributed molecular markers that have been widely utilized to assess genetic diversity and genetic mapping for important traits in plants. However, the understanding of microsatellite characteristics in Arachis species and the currently available amount of high-quality SSR markers remain limited. In this study, we identi...
