Mejoramiento genético. Mejoramiento de caracteres. Mayor fijación de N
The selection criteria for N fixation at CIAT includes plant vigor, nodule no., mass at mid-flowering, acetylene reduction activity, total N, and grain yield of materials grown in sand culture and in field trials with mild N stress. The breeding program has yielded materials with improved N2-fixatio...

| description | The selection criteria for N fixation at CIAT includes plant vigor, nodule no., mass at mid-flowering, acetylene reduction activity, total N, and grain yield of materials grown in sand culture and in field trials with mild N stress. The breeding program has yielded materials with improved N2-fixation; with a greater understanding of the associated plant characters, choice of parents to combine these different characters, and refinement of the selection criteria, more progress is likely. In addition to these studies, evaluations were conducted with 2 sets of Rhizobium strains for their ability to compete against native strains. The results of these trials are presented in table form.

The breeding program has yielded materials with improved N2-fixation; with a greater understanding of the associated plant characters, choice of parents to combine these different characters, and refinement of the selection criteria, more progress is likely.

(CIAT) El criterio de seleccion por fijacion de N utilizado en CIAT incluye vigor de la planta, no. de nodulos, masa a mediados de la floracion, actividad de reduccion de acetileno, N total y rendimiento de grano de los materiales cultivados en arena y en los ensayos de campo con ligero estres de N. El programa de mejoramiento ha producido materiales con fijacion de N mejorada; con un mayor conocimiento de las caracteristicas de la planta asociadas, la seleccion de progenitores para combinar estas diferentes caracteristicas y el refinamiento de los criterios de seleccion, se pueden esperar mas avances. Adicionalmente a estos estudios, se realizaron evaluaciones con 2 grupos de cepas de Rhizobium por su capacidad para competir con las cepas nativas. Los resultados de estos ensayos se presentan en forma de cuadro.
