A standard conservation strategy for plant genetic resources integrates in situ (on-farm or wild) and ex situ (gene or field bank) approaches. Gene bank managers collect ex situ accessions that represent a comprehensive snap shot of the genetic diversity of in situ populations at a given time and place. Although simple in theory, achieving complementary in(More)
An efficient germplasm collecting method was evaluated using six Lupinus species and the Spanish Lupinus collection as a study case. This method includes the application of geographic information systems, ecogeographical land characterization maps, species distribution models and gap analysis to identify prioritized collecting sites. To evaluate the(More)
An intense exploration of the Spanish Cantabrian coast for the presence or absence of wild Brassica oleracea L., yielded 24 new localities to be added to the 21 previously known. Of the resulting 45 localities, 22 correspond to Asturias, 11 to Cantabria and 12 to the Basque Country. Data on the habitat requirements of this plant have been annotated, the(More)
Information on plant adaptation can be very useful in agrobiodiversity studies. Ecogeographical land characterization (ELC) maps constitute a new tool in this direction with great potential. To assess the usefulness of this approach, an ELC map of Spain was created through multivariate methods. Its performance to characterize plant habitat preferences was(More)
Ullucus tuberosus (common name ‘ulluco’) is a popular tuber crop of Andean highlands. Until now attention has been focused on ulluco from Bolivia, Peru and Ecuador, but little is known about its diversity in Colombia. Thirty-six accessions of cultivated ulluco preserved in the Gene Bank of the Universidad Nacional de Colombia were studied to assess the(More)

In Argentina, species of the genus Trichloris represent an important native forage resource adapted to drought and salinity. The capture and identification of adaptive traits associated with such conditions require long-term collection and characterization efforts. Ecogeographical land characterization (ELC) maps constitute an easy and useful tool to(More)
Drought, one of the most important abiotic stress factors limiting biomass, significantly reduces crop productivity. Salinization also affects the productivity of both irrigated and rain-fed wheat crops. Species of genus Aegilops can be considered crop wild relatives (CWR) of wheat and have been widely used as gene sources in wheat breeding, especially in(More)
