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 ...

“Diquís”, variedad de frijol común rojo brillante
More than 60% of common bean production worldwide is derived from cultivars of Middle American origin. Understanding the diversity of these will facilitate their use in genetic improvement. The objective of this study was to analyze a collection of 269 landraces of common bean (Phaseolus vulgaris...

The larva of the bean pod weevil (BPW), Apion godmani Wagner (Coleoptera: Curculionidae), causes serious yield losses in common bean (Phaseolus vulgaris L.) in Mexico and Central America, by consuming the seed as it develops in the immature pod. Resistance to the BPW was identified in bean germpl...
