The main theme of this book deals with recent advances in understanding the organization and use of diversity in Phaseolus species, integrated genetic improvement of the common dry bean (P. vulgaris, the world's most important pulse crop), and integrated management of abiotic and biotic production constraints. Combined use of the best of the conventional and modern genetics and breeding technologies and crop management practices for sustained production of this nutritious food are elegantly documented for the first time in this volume. The authors represent a worldwide team of eminent bean researchers. They have prepared a state-of-the-art account on most relevant topics and offer their insights into research directions for the twenty-first century. Food legume researchers in general and those working on beans in particular, advanced degree students, and college professors should find this an excellent reference book and guide for their work.
