Status of the Ex Situ and In Situ Conservation of Brazilian Crop Wild Relatives of Rice, Potato, Sweet Potato, and Finger Millet: Filling the Gaps of Germplasm Collections

This study presents the status of ex situ and in conservation for crop wild relatives rice, potato, sweet finger millet Brazil, subsequent germplasm collection expeditions. research is part a global initiative entitled “Adapting Agriculture to Climate Change: Collecting, Protecting, Preparing Crop Wild Relatives” supported by Global Diversity Trust. Species primary, secondary, tertiary gene pools with occurrences reported Brazil were included: Oryza alta Swallen, O. grandiglumis (Döll) Prod., latifolia Desv., glumaepatula Steud., Eleusine tristachya (Lam.) Lam., E. indica (L.) Gaertn., Solanum commersonii Dunal, S. chacoense Bitter, Ipomoea grandifolia (Dammer) O’Donell, I. ramosissima (Poir.) Choisy, tiliacea (Willd.) triloba L., cynanchifolia Meisn. The each taxon was assessed using gap analysis methodology, results used plan 16 Seeds collected material evaluated viability, protocols seed germination cryopreservation tested. final score, resulting from including average scores, resulted classification medium priority all species, exception (high priority). total accessions (174) almost doubled these incorporated Embrapa’s system prior 2015. In addition, practically absent species system, such as indica, chacoense. methods dormancy breaking low temperature Oryza, Eleusine, promising incorporation respective banks. show importance efforts collect conserve based on previous analysis. complementarity strategy also appears be very country.
