Book Description
The common bean (Phaseolus vulgaris L. ) is the most important pulse crop in the world. It is an important source of calories, proteins, dietary fibers, minerals, and vitamins for millions of people in both developing and developed countries worldwide. It complements cereals and other carbohydrate-rich foods in providing near-perfect nutrition to people of all ages. Moreover, a regular intake ofbeans helps lower cholesterol and cancer risks. Despite the fact that per capita consumption of common bean in some developed countries (e. g. , the U. S. A. ) has been increasing over the last several years, in general, the average global per capita consumption is declining because production is unable to keep up with the population growth. Moreover, increasing demand for pesticide-free food products, concern for natural resources conservation, and the need to reduce production costs offer daunting challenges to the twenty-first century policy makers, bean growers, and researchers alike. High yielding, high quality bean cultivars that require less water, fertilizers, pesticides, and manual labor combined with integrated management of abiotic and biotic stresses will have to be developed. Eminent bean researchers were invited to contemplate these issues, prepare a state-of-the-art account on most relevant topics, and offer their insight into research directions into the twenty-first century. Four excellent books have been published covering various aspects ofthe common bean since 1980. These books are: I) Bean Production Problems nd in the Tropics (l SI ed. 1980, 2 ed. 1989), H. F. Schwartz & M. A.

Book Description
Common bean is one of the most important legume crops especially in developing countries like eastern and southern Africa. Though bean is important in these areas its production is affected by a number of abiotic stresses including low soil fertility and drought. However, in these countries the population growth rate is increasing therefore, there is need to find mechanisms to increase crop productivity. Previous studies on bean roots have shown that bean genotypes vary for root phenotypes, which enhance drought and low phosphorus tolerance. These traits include basal root whorl number, basal root number, adventitious roots, root etiolation, root growth angle and root hairs. These traits can be regulated by genes, by the environment or both. In Africa farmers have different preferences for different bean genotypes depending on color, seed size, resistant to stresses and maturity period. Hence in developing new bean cultivars, farmer's preferences should be taken into consideration. In this study we evaluated phenotypic variation for a number of root traits and their relation to phosphorus uptake. The genotypes which we evaluated in this study were first screened in another study, which evaluated bean genotypes for superior adaptation to low soil fertility and drought, this study was the Bean Improvement for Low Soil Fertility in Africa (BILFA) program. These genotypes were found to have varying performance under low soil fertility and drought. From that BILFA study we selected eleven genotypes to be used in our study and four non-BILFA genotypes making a total of fifteen genotypes. These non-BILFA lines are commercial cultivars in Malawi. Our study included both greenhouse and field experiments. The fifteen genotypes were phenotyped for root traits. Our data from the phenotyping study showed that the existing cultivars had less basal root whorl number compared to the BILFA lines. In an attempt to improve the adaptation of these cultivars to low phosphorus availability, we attempted to increase their basal root whorl number by hybridization between these commercial varieties, which have one whorl with four whorled genotypes.

Book Description
The period following the second world war has witnessed an expanding commitment to incr~ased food production in tropical countries. Public and private initiatives at the national and international levels have led to the creation of programs geared specifically towards the improvement of food crops in tropical conditions. Examples of this increased commitment are the network of international agricultural research centers and numerous bilateral aid projects. As a consequence, crop improvement has become a truly worldwide endeavor, relying on an international network of institutions and collaborators. This holds also for Phaseolus beans. Following the discovery of the Americas, Phaseolus beans became distributed on all six continents. Yet, until not so long ago, most of the research on Phaseolus improvement took place in developed countries. In recognition of the nutritional importance of Phaseolus beans in developing countries, this has changed considerably in the last years, principally perhaps through the activities of the Centro Internacional de Agricultura Tropical (CIAT) and the International Board for Plant Genetic Resources (IBPGR). Consequently, the scope of the research on Phaseolus has broadened considerably and the number of Phaseolus researchers is larger than ever before.
