Total seed protein variability in a sample of 163 entries of year-bean (Phaseolus polyanthus), including wild, feral and cultivated forms of the whole range of distribution in Latin America was studied using 1-dimensional SDS/PAGE and 2-dimensional IEF-SDS/PAGE. Ten different patterns were observ...

Random amplified polymorphic DNA (RAPD) markers were used for assessing genetic diversity and its structure in a collection of the drought-tolerant, tropical multipurpose shrub legume Flemingia macrophylla (Willd.) Merrill. The species is especially suited to low-input smallholder production syst...

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...

This paper uses the spatial analysis tools DIVA and FloraMap to identify potential areas for the in situ conservation of a set of 10 forage species. We introduce the idea of roadside verges as conservation areas and discuss the risks and opportunities of two potential scenarios for conservation. ...

Review of the classification, geographic distribution, animal performance and productivity of trypanotolerant cattle, sheep and goats in 18 countries of west & central Africa, particularly N'dama cattle, West African Dwarf Shorthorn, and Zebu x N'Dama crossbreeds. Discussion on potential utilizat...

For P. erosus, P. ahipa and P. tuberosus, descriptions are given of the taxonomy, botany, morphology, ecology, reproductive biology, agronomy, N fixation, chemical composition, nutritive value, uses, origin of the cultivated species (with descriptions of the wild species P. ferrugineus and P. pan...


Sørensen, M.Leibniz Institute of Plant Genetics and Crop Plant Research[Yam bean, Pachyrhizus DC.]Yam bean, Pachyrhizus DC.

At least 25 species of root and tuber crops from 16 genera and 15 families are native to South America. Apart from the 7 species of potato (Solanum spp.), there are nine lesser known species native to the Andes that are grown for their edible underground organs and are traditionally, but not excl...
