Crosses were made and cv. and lines selected to combine the existing resistance to Xanthomonas campestris pv. phaseoli with adaptation to the tropics and to determine new sources of resistance. Crosses were made between adapted lines and sources of resistance, some with Great Northern genes. The ...

The Central American Adaptation Nursery (VIDAC 1988), comprising the best black- and red-seeded lines evaluated in the 1987 VIDAC, was established to identify well-adapted bean genotypes and obtain information on their degree of resistance to different crop problems. Outstanding (1) black-seeded ...
Root rots occur in all the zones where beans are cultivated in the world. Fusarium spp., Pythium spp., Rhizoctonia solani, Sclerotium rolfsii, and Macrophomina phaseoli are found among the responsable microorganisms. Each pathogen developes according to its own optimum conditions. Problems are gr...
At the Apion nursery, Asuncion Mita, Jutiapa, several entries from the Guatemalteco Germplasm Bank (some formerly reported as resistant), entries from CIAT preliminary yield trials (EP-81), and individual selections from Linea 17 and from the International Apion Nursery were assessed for resistan...

A brief account of the bean breeding program for resistance to Thanatephorus cucumeris from 1981 to 1986 at CIAT and for Central America and the Caribbean is presented. Black and red bean parents used in the crossing programs are listed. While population selections have all been conducted under f...
