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...

The bean (Phaseolus vulgaris) cultivar Jules and the PI 207262 line are moderately resistant to Xanthomonas campestris pv. phaseoli in the temperate zone but appeared susceptible in field evaluations in the tropics. Susceptibility to the pathogen was related to environmental factors that caused v...

Data obtained from the international Bean Rust Nursery (IBRN) in 1975-76 showed that none of the 132 cv. and breeding lines tested was resistant to bean rust; however, some were susceptible only in specific geographical regions. CIATs bean program has concentrated its efforts on selecting rust-re...

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...
