A total of 150 microsatellite markers developed for common bean (Phaseolus vulgaris L.) were tested for parental polymorphism and used to determine the positions of 100 genetic loci on an integrated genetic map of the species. The value of these single-copy markers was evident in their ability to...

A survey of selected fields in bean growing regions of Tanzania and a more detailed survey of bean fields in the Lushoto area of northern Tanzania were carried out to establish soil properties limiting the extent of root nodulation of Phaseolus vulgaris L. Soil samples were collected and soil pH,...

Breeding of Phaseolus vulgaris L. for resistance to common bacterial blight (CBB) can be done with visual evaluations of symptoms to distinguish broad resistance classes, but a more quantitative measure was needed for genetic studies of resistance. A novel method of evaluation was developed by qu...

The Rwandan civil war escalated in 1994, killing 800 000 people and displacing another 2 million. Agriculture, the occupation of over 90% of the Rwandans was acutely affected as violence peaked in the middle of the growing season. This article analyses the effects of the war on bean varietal dive...

With the advent of biotechnology and the emergence of property rights in genetic materials, the distribution of benefits from genetic resources is an issue of growing importance. Farmer's Rights is a concept that has emerged to seek to insure appropriate compensation to farmers for their contribu...
