The taxonomic classification of the wild Lima bean complex needs to be assessed to select species for use in breeding programs and to identify genetic resources for conservation. The objectives of this study were to determine the genetic relationships among, and the phylogeny of, wild Lima bean (...

AFLP fingerprinting of Phaseolus lunatus L. and related wild species from South America
Cultivars of common bean (Phaseolus vulgaris L.) capable of yielding well at low levels of native or added phosphorus (P) are highly desirable in many tropical production systems. The objective of the present study was to identify geographical regions which might be sources of such genotypes. A t...

A geographical approach to identify phosphorus-efficient genotypes among landraces and wild ancestors of common bean
Crop wild relatives that have experienced multiple and independent domestication events provide an excellent model for understanding adaptation processes in crop populations and a first and relevant aspect to investigate is the geographic origin of landraces. The aim of this research was to estab...

Multiple origins of Lima Bean landraces in the Americas: evidence from chloroplast and nuclear DNA polymorphisms
Chloroplast DNA (cpDNA) diversity has been examined using PCR-RFLP and RFLP strategies for phylogenetic studies in the genus Phaseolus. Twenty-two species, including 4 of the 5 cultivated species (P. lunatus L., the Lima bean; P. vulgaris L., the common bean; P. coccineus L., the runner bean and ...

Molecular evidence for an Andean origin and a secondary gene pool for the lima bean (Phaseolus lunatus L.) using chloroplast DNA
Plant-to-plant phenotypic variation has been observed within accessions of S. capitata maintained at the Centro Internacional de Agricultura Tropical (CIAT) since shortly following introduction. A small experiment was conducted to determine the potential importance of natural outcrossing as a cau...

Discovery of new spontaneous sources of amylose-free cassava starch and analysis of their structure and techno-functional properties
Technological advances allow us to tap into genetic resources to address food and nutritional security in the face of population growth, urbanization, climate change, and environmental degradation. It is vital, particularly for developing countries, to ensure that the policy framework regulating ...
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...
