ACKNOWLEDGMENTS

The ideas presented here developed from discussions with many colleagues, and I wish to thank them for
their inputs. Particular thanks go to Drs. Steve Beebe, John Miles, Mabrouk El-Sharkawy, and Peter
Wenzl for constructive comments that helped improve the manuscript. I gratefully acknowledge the con-
tributions of past and present colleagues of the Beans and Tropical Forages projects at CIAT. I also thank
CIAT’s collaborators from several national programs in Latin America and Africa for their valuable con-
tributions to selection and breeding efforts over the years. I am very grateful to Elizabeth de Páez for ed-
itorial corrections of the manuscript.
