    Abstract/Description
    In 1984 the breeding for enhanced N fixation in agronomically acceptable bean cv. was continued. RIZ lines 10, 13, and 29 are performing well in international nurseries. They have high yield, good grain type, broad adaptation, and some disease resistance; however, it is difficult to assess if they support more fixation and get a greater proportion of their N from fixation. As a result, a research project was started which will utilize the (15)N isotope
     
    En 1984, se continuo el mejoramiento para incrementar la fijacion de N en cv. de frijol agronomicamente aceptables. Las lineas RIZ 10, RIZ 13 y RIZ 29 se comportan bien en viveros internacionales. Presentan altos rendimientos, buen tipo de grano, amplia adaptacion y alguna resistencia a enfermedades; sin embargo, es dificil determinar si soportan mas fijacion y obtienen una mayor proporcion de N a partir de la fijacion. Como resultado, se inicio un proyecto de investigacion que utilizara el metodo de dilucion del isotopo N15 para evaluar la fijacion de N en las lineas RIZ seleccionadas. (RA-CIAT)
