Abstract: El estudio del género Lupinus L. (Fabaceae) presenta un elevado número de especies y ha ocasionado muchas controversias en su taxonomía, razones que han motivado realizar el estudio de las especies de este género y sus simbiontes en el distrito de Corongo, provincia de Corongo, departamento de Ancash, no existiendo aún antecedentes de estudios semejantes en esta zona. Se colectaron muestras botánicas y nódulos bacterianos, realizando un análisis in situ, y en laboratorio, utilizando descriptores estandarizados. Con estos datos se confeccionaron matrices para las diez especies estudiadas del género Lupinus: L. subtomentosus C.P. Sm, L. mutabilis Sweet., L. brachypremnon C.P Sm, L. carazensis Ulbr., L. lindleyanus J. Agardh, L.aff mutabilis, L. eriocladus Ulbr, L. aridulus C.P. Sm, L. weberbaueri Ulbr., L. paniculatus Desr; y sus correspondientes bacterias simbióticas; siete de las cuales pertenecen al género Bradyrhizobium y tres a Mesorhizobium, obteniéndose fenogramas independientes, para luego generar un árbol de consenso, usando para cada caso el algoritmo UPGMA con el software NTsys 2.2, con cuyo análisis se llega a la conclusión de que las características de los nódulos bacterianos y sus simbiontes podrían ser usados para mejorar los estudios taxonómicos del género Lupinus, al menos bajo las condiciones de estudio. Así mismo, se amplia el área de distribución de L. aridulus para la zona de estudio en el departamento de Ancash.
While many botanical groups have received study, some plant genera lack complete information on their number of species. Such is the case with the genus Lupinus L. (Fabaceae), which has many described species and their taxonomy remains controversial. With this a background, we have investigated studies into the diversity of Lupinus species and their symbiotic bacteria in the District of Corongo, Province Corongo in the Department of Ancash on the western slope of the Andes in northern Peru. Both botanical and bacterial nodules samples were collected, including an in situ analysis, and subsequently in the laboratory using standardized descriptors. Using these data, a matrix was constructed for ten species of Lupinus: L. subtomentosus C.P. Sm, L. mutabilis Sweet., L. brachypremnon C.P Sm, L.. carazensis Ulbr., L. lindleyanus J. Agardh, L.aff mutabilis, L. eriocladus Ulbr, L. aridulus C.P. Sm, L. weberbaueri Ulbr., L. paniculatus Desr; and their nodules and bacteria, usually Bradyrhizobium but three species with Mesorhizobium also. Phenograms for each were generated and a consensus tree constructed using the algorithm UPGMA of NTsys 2.2 software. Our analysis suggest that nodules and their characteristic bacteria may be useful as additional taxonomic markers, at least under these specific study conditions. Besides, the distribution area for L. Aridulus is extended to District of Corongo – Ancash.
