Crop diversity underpins the productivity, resilience and adaptive capacity of agriculture.
Loss of this diversity, termed crop genetic erosion, is therefore concerning. While alarms …

The circulation of seed among farmers is central to agrobiodiversity conservation and
dynamics. Agrobiodiversity, the diversity of agricultural systems from genes to varieties and …

Landraces cultivated in centers of crop diversity result from past and contemporary patterns
of natural and farmer‐mediated evolutionary forces. Successful in situ conservation of crop …

Climate change is predicted to have major impacts on small-scale farmers in Mexico whose
livelihoods depend on rain-fed maize. We examined the capacity of traditional maize seed …

This paper reviews and discusses how studies on (i) on-farm diversity assessment,(ii)

More than 70 years after the first ex situ genebanks have been established, major efforts in
this field are still concerned with issues related to further completion of individual collections …

Traditional landraces of maize are cultivated throughout more than one-half of Mexico's
cropland. Efforts to organize in situ conservation of this important genetic resource have …

Background The limited genetic diversity of elite maize germplasms raises concerns about
the potential to breed for new challenges. Initiatives have been formed over the years to …

A better knowledge of factors organizing crop genetic diversity in situ increases the
efficiency of diversity analyses and conservation strategies, and requires collaboration …
