All commercially grown bean var. in Central America of small shiny red grain type are susceptible to one or more strains of BCMV. An attempt was made to recombine the important var. characteristics of var. such as Honduras 46, Rojo Zamorano, Nahuizalco, Rojo de Seda, and Desarrural, in addition t...

Conversion de cultivares de frijol (P. vulgaris) susceptibles al BCMV, a cultivares resistentes mediante la incorporacion de la resistencia hipersensible
While symbiotic nitrogen (N2) fixation by G. max and P. vulgaris reduces their need for combined N, N2 fixation under field conditions is rarely maximized. This paper reviews constraints to N2 fixation in these species, then examines the genetic variability recorded for traits affecting N2 fixati...

Selection for improved nitrogen fixation in Glycine max (L.) Merr. and Phaseolus vulgaris L.
CIATs bean improvement program has the objective of generating and fomenting the production of high-yielding materials and extensive combinations of resistance to factors that adversely affects the production of the crop. The general strategy is to (a) make bean cultivation more productive, profi...

Estrategia general del mejoramiento genetico del frijol en el CIAT
In search of tolerance to BGMV, screening of 41 F2 and F3 populations of a group of crosses from CIAT was started in Guatemala in 1977. In 1978, some F4 F5 and F6 selections were evaluated in preliminary yield trials with high infection pressure. In 1979 the best F7 and F8 lines were widely teste...
