Summary
Approximate identifications and ambiguity in accession identities undermines planning and decisions around conservation.Without precise information on accession identities, it is difficult to determine which populations are most important or threatened and in need of priority conservation. This limits effective conservation planning and resource allocation. Ambiguous accession identities also impact the ability to monitor trends in diversity over time.Without consistent and precise information on specific accessions, it is challenging to determine if populations are declining, stable or increasing. This limits the ability to assess threats and determine appropriate conservation responses. Uncertain accession identities reduce the utility of collections for future breeding. Without precise information on the identity, origins and characteristics of accessions, plant breeders cannot make informed selections of germplasm for crossing and development. This limits the potential uses of conserved germplasm for crop improvement. In summary, achieving high quality data on the taxonomic identity and diversity of accessions is critical for enabling effective conservation planning, diversity monitoring and use of collections for plant breeding and crop improvement.Approximate identifications and uncertain accession data undermine these efforts and reduce the impacts and benefits of conservation. Precision in accession identification and data should therefore be a high priority.
Plant genetic conservation provides theoretical and practical information about conserving plant genetic variation. The book initially offers knowledge on characterizing and evaluating plant genetic resources. The authors discuss strategies from in situ and ex situ conservation to crop wild relative breeding. They explore how these strategies can improve food security despite agrobiodiversity loss, population growth and climate change. Each chapter provides examples from literature or authors’ research.

Chelsea Smith valuates crop wild relatives (CWR) used for crop breeding.While ex situ conservation and selected species are targeted, most diversity remains threatened. She recommands recognizing other CWR values , developing alternative valuation integrating perspectives to achieve optimum conservation.
