Cassava (Manihot esculenta Crantz) is an important food security crop or resource for poor rural communities particularly in Africa. The crop’s ability to produce high yields even under poor conditions and storability of its roots underground for longer periods or until needed makes it a model ‘f...

This paper discusses the strategic use of existing genetic diversity in addressing the constraints faced by yam (Dioscorea sp.) production in Bénin, including pest and disease pressure, poor soil and changing climate. Participatory strategies that have been developed to preserve their diversity i...

Studies to quantify genetic variation in cassava germplasm, available within the national breeding programmes in Africa, have been limited. Here, we report on the nature and extent of genetic variation that exists within 1401 cassava varieties from seven countries: Tanzania (270 genotypes); Ugand...

Genetic diversity of common beans is presented for subdivisions of Mesoamerican groups. Three subgroups were identified by means of molecular markers, such as proteins (phaseolin) and allozymes.

The Random Amplification of Polymorphic DNA (RAPD) analysis was used to detect the genetic diversity among Ugandan isolates of Xanthomonas campestris pv. musacearum (Xcm), the causal agent of banana Xanthomonas wilt (BXW) disease. Seven random primers were used because of their ability to amplify...
