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...

Maca is an edible root crop of the crucifer family endemic to the Puna of the high Andes in Central Peru around Lake Junin, a chilly plateau at 4000 m altitude. Grown in the late 1980s exclusively in its native area, on no more than 50 ha, maca has experienced over the last years a meteoric rise ...

Dioscorea alata L. is one of the most widely grown and economically important yam species. Hundreds of accessions are maintained ex situ in germplasm collections and have been characterized with descriptors but new tools are still needed to assess tuber chemical composition. The objectives of the...

Guinea yams (Dioscorea cayenensis-rotundata complex; D. rotundata Poir. and D. cayenensis Lam.) have been described as resulting from a process of domestication of wild yams of the section Enantiophyllum by African farmers. Although currently practised by few farmers, the process of yam domestica...

Local varieties of leafy kales ( Brassica oleracea L.) are grown in home gardens in Calabria and Sicily for self-consumption, in the same area where the wild relative Brassica rupestris Raf. also grows. With the use of AFLP markers, comparisons were made of the genetic diversity and population st...
