The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that r...

Argentina produce poroto para exportar ya que el consumo interno es mínimo de 0,240 kg, habitantes, año, lo que significa 7,920 TM anuales. En 1995 la exportación fue de 61,548 TM de alubia; 99,567 TM de negro y 19,323 TM de otros tipos de comerciales. Más del 90% de la producción de poroto se re...

Seven perennial species of African origin-Brachiaria arrecta, B. brizantha, B. decumbens, B. dictyoneura, B. humidicola, B. mutica, and B. ruziziensis-have been used as fodder plants, particularly in tropical America. The history of the commercial cultivars is given, and their most important attr...

We reviewed 97 species of the genus Brachiaria, spanning the whole taxon. The species were arranged in groups according to perceived natural affinities. The morphology of the inflorescence, especially the spikelet, was examined in detail and found to be highly variable; accordingly, the number of...

Fifty-four accessions of Phaseolus vulgaris cultivated in Spain and representing a broad variability for this country, were studied together with 30 samples of wild forms of American origin. Two reference cultivars (from the Andes and Mesoamerica) plus two outgroups (P. coccineus and Vigna unguic...
