“…Greater utilization of genetic resources from crop progenitors and related wild species (i.e., crop wild relatives—CWRs) is urgently called for to increase agricultural productivity and sustainability (Dempewolf et al., 2014; Kell, Heywood, & Maxted, 2005; Kell et al., 2015; Lala, Amri, & Maxted, 2018; Vincent et al., 2013). As compared to their domesticates, CWRs typically harbour higher levels of genetic variation in key agronomically and horticulturally valuable traits (Fielder et al., 2015).…”

Crop wild relatives (CWRs) offer novel genetic resources for crop improvement. To assist in the urgent need to collect and conserve CWR germplasm, we advance here the concept of an “evolutionary” approach. Central to this approach is the predictive use of spatial proxies of evolutionary processes (natural selection, gene flow and genetic drift) to locate and capture genetic variation. As a means to help validate this concept, we screened wild‐collected genotypes of woodland strawberry (Fragaria vesca) in a common garden. A quantitative genetic approach was then used to test the ability of two such proxies—mesoclimatic variation (a proxy of natural selection) and landscape isolation and geographic distance between populations (proxies of gene flow potential)—to predict spatial genetic variation in three quantitative traits (plant size, early season flower number and flower frost tolerance). Our results indicated a significant but variable effect of mesoclimatic conditions in structuring genetic variation in the wild, in addition to other undetermined regional scale processes. As a proxy of gene flow potential, landscape isolation was also a likely determinant of observed patterns—as opposed to, and regardless of, geographic distance between populations. We conclude that harnessing proxies of adaptive and nonadaptive evolutionary processes could provide a robust and valuable means to identify genetic variation in CWRs. We thus advocate wider use and development of this approach amongst researchers, breeders and practitioners, to expedite the capture and in situ conservation of genetic resources provided by crop wild relatives.

“…A recent article published by Kell et al (2015) highlights the significant impact of CWR on agriculture, horticulture, and the world economy. Referencing several researchers and using the example of China (one of the most important centers of plant diversity, with more than 30 000 native higher plant species), they emphasize the crucial role of such species in food security and economic stability and report that high-priority native wild relatives are threatened.…”

“…However, like many other wild plants, CWR face threats such as intensive agriculture, urban development, pollution and biological invasions (Bilz et al ., ; Kell et al ., , ) and thus command urgent conservation attention (Maxted et al ., ; Heywood et al ., ; Kell et al ., ). This conservation need is recognized in international policy and legislation, including the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA; FAO, ), CBD Strategic Plan (SCBD, ) and Global Strategy for Plant Conservation 2011–2020 (SCBD, ), the Second Global Plan of Action for Plant Genetic Resources for Food and Agriculture (FAO, ) and the EU Biodiversity Strategy to 2020 (EP, ).…”

Aim To create a crop wild relative (CWR) conservation strategy for the Czech Republic: the first national CWR conservation strategy for Central and Eastern Europe. Location Czech Republic. Methods We generated a CWR checklist for the Czech Republic and then prioritized taxa, using widely adopted criteria modified with input from local experts, to create a national CWR inventory. For 204 priority CWR species, we collated 206,760 presence records. We carried out spatial analyses to identify patterns in species richness, gaps in existing conservation actions, complementary conservation networks and collecting strategies to increase representativeness of gene bank accessions. We considered both specific and genetic conservation, using geographic and ecogeographic proxies for the latter. Results Passive in situ conservation of CWR in the Czech Republic is comprehensive at present, with all but one priority CWR species being contained in protected areas. Active in situ CWR conservation could be focussed within 11 ca. 10‐km‐by‐10‐km grid cells containing 94% of priority species, or their overlapping protected areas. To augment the genetic coverage of the in situ conservation network, active CWR conservation is encouraged within 11 supplementary areas. Meanwhile, there are huge gaps in ex situ collections, with no known conserved material for 134 of the 204 priority species. Furthermore, existing accessions are generally unrepresentative of genetic diversity. Main conclusions In the Czech Republic, active in situ conservation of priority CWR should be instigated within the 22 recommended grid cell areas or their 14 overlapping protected areas. For ex situ conservation, strategic and targeted collection of germplasm would markedly increase the value of gene bank collections. Diversity of priority Czech CWR is concentrated in South Moravia, making this a particularly important CWR area for the country and for Europe.
