In 1984, most of the pathology efforts of the CIAT Bean Program concentrated on the evaluation of bean germplasm for their reaction to the main bean pathogens under field conditions in several international nurseries throughout many of the bean growing areas. High priority was given to the most w...

The degree of genetic diversity of 127 Colletotrichum gloeosporioides isolates from Stylosanthes guianensis genotypes in South America was measured at the molecular level by random amplified polymorphic DNA (RAPD) with nine arbitrary primers of 10 bases, and by restriction fragment length polymor...

Use of genetic resistance is the most practical and economic way to manage anthracnose of common bean. Colletotrichum lindemuthianum, the causal agent of bean anthracnose, is a highly variabile pathogen, and there are no host resistance genes that are effective against all known races of the path...

Assembled germplasm has provided breeders with valuable traits for the improvement of common beans. Molecular markers such as phaseolin and isozymes have facilitated understanding of the genus Phaseolus thus enabling breeders to develop more effective strategies. However, there are still gaps in ...
