    Abstract/Description
    During 1986, research emphasis was shifted to BGMV while BCMV research focused on the incorporation of blackroot resistance in African germplasm and the backcrossing of I gene into Latin American var. The identification of alternate host plant species for BGMV is critical in the understanding of the endemic and epidemic characteristics of this virus. Using the artificial inoculation methodology implemented at CIAT, the evaluation of 57 plant species considered as possible BGMV hosts was initiated. To date, Phaseolus lunatus, P. coccineus, P. acutifolius, Canavalia sp., Vigna radiata, and Macroptilium lathyroides have been shown to be potential reservoirs of BGMV in nature. Preliminary isolation work conducted with the CIAT isolate of BGMV resulted in purified preparations of acceptable concn. Various bean chlorotic mottle virus isolates have been made and are currently being characterized. Results are included in table form. (CIAT)
     
    Durante 1986 el enfasis en investigacion se desplazo hacia BGMV en tanto que la investigacion sobre BCMV se enfoco hacia la incorporacion de la resistencia a la pudricion negra en el germoplasma africano y el retrocruzamiento del gen I a var. latinoamericanas. La identificacion de especies de plantas hospedantes alternas para BGMV es critica debido a las caracteristicas endemicas y epidemicas de este virus. Utilizando la metodologia de inoculacion artificial llevada a cabo en CIAT, se inicio la evaluacion de 57 especies de plantas consideradas como posibles hospedantes del BGMV. Hasta la fecha, Phaseolus lunatus, P. coccineus, P. acutifolius, Canavalia sp., Vigna radiata y Macroptilium lathyroides han mostrado ser reservorios potenciales de BGMV en la naturaleza. El trabajo de aislamiento preliminar realizado con el aislamiento de BGMV del CIAT dio como resultado preparaciones purificadas de concn. aceptable. Se han efectuado varios aislamientos del virus del moteado clorotico del frijol, los cuales se estan caracterizando actualmente. Se dan los resultados en forma de cuadro. (CIAT)
