Los sistemas silvopastoriles son útiles para mejorar el bienestar animal, la producción de leche y carne, y al mismo tiempo hacer la producción ganadera más amigable con el medio ambiente. Por lo general, un sistema silvopastoril incluye especies arbóreas que proveen sombra a los animales, y arbu...

The genetic variable of seven Phaseolus taxa has been evaluated on the basis of molecular data and the results have used to clarify the phyletic relationships between several taxa of the P. coccineus L. complex. Chloroplast DNA (cpDNA) from 33 populations was digested with six restriction endonuc...

During a review of Phaseolus under-taken by the senior author to clarify the variability of the P. coccineus L. species complex, a few herbarium specimens of what appeared to be a new species from Costa Rica and Panama were encountered. Subsequent field collecting by the junior author confirmed t...

The construction of a detailed genetic map of cassava (Manihot esculenta Crantz) will be useful to tag agronomically important trais as well as to isolate and to clone cassava genes in the future. This map will also contribute to the understanding of cassava genomic structure and evolution. As a ...


Angel, F.Giraldo, F.Gómez, R.Iglesias, C.A.Tohme, Joseph M.Roca, William M.[Use of RFLPs and RAPDs in cassava genomic studies]Use of RFLPs and RAPDs in cassava genomic studies

We mapped the distribution of Mononychellus spp. associated with cassava based on survey of 1264 fields in thirteen Central and South American countries. We collectred M. tanajoa (Bondar) in Panama, Colombia, Venezuela, Guyana, Trinidad and Tobago, Brazil and Paraguay, but not north of Panama, no...
