Cultivars of common bean (Phaseolus vulgaris L.) capable of yielding well at low levels of native or added phosphorus (P) are highly desirable in many tropical production systems. The objective of the present study was to identify geographical regions which might be sources of such genotypes. A t...

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...

A polymerase chain reaction approach using degenerate primers that targeted the conserved domains of cloned plant disease resistance genes (R genes) was used to isolate a set of 15 resistance gene analogs (RGAs) from common bean (Phaseolus vulgaris). Eight different classes of RGAs were obtained ...
