Genetic Erosion: Context Is Key
2015Genetic erosion is a useful concept for conservationists, collection curators, natural lands managers, and practitioners of restoration and revegetation. However, there is variation in how the term has been used and how faithfully it follows from the genetic concepts upon which it was based.

The domestication and genetic erosion of maize
Economic Botany, 1974The genetic variability available for selection is the raw material for crop improvement. However, the process of domestication itself restricts the range of genetic variation, which eventually limits the crop's selective response to small gains and increases the crop's vulnerability to parasites.

This chapter surveys the conceptual basis of indicators of genetic diversity, genetic erosion, and genetic vulnerability. These are summary measures of genetic diversity in cultivated plants and their wild relatives that guide decisions, monitor progress, and warn of emerging issues of genetic resources for resilient agricultural production.

Genetic Diversity and Erosion—A Global Perspective
2015Biodiversity is continually declining, according to global biodiversity indicators (Butchart et al. in Science 328:1164–1168, 2010). Population trends, habitat extent, habitat condition, and composition of species communities—indicators of the state of diversity—are declining, while at the same time pressures on biodiversity posed by resource ...

Diversity and Erosion in Genetic Resources of Spices
2015Genetic resources are global assets of inestimable value to human kind, which holds the key to increasing food security. The loss of variation in crops due to the modernization of agriculture has been described as genetic erosion. The current status of the genetic diversity and erosion in spice crops is discussed in this chapter.

Plant genetic resources and genetic erosion
2015Main aim of plant breeding is creation of new genotypes with superior agronomic traits. Genetic difference is base for breeding success and it can be find in plant genetic resources (from wild relatives to breeding material). Plant genetic resources are important for agriculture, nutrition, environment protection, sustainable production, preservation ...

Genetic Diversity and Erosion in Berries
2015Fragaria (strawberry; Rosaceae), Rubus (brambles: raspberry and blackberry; Rosaceae), and Vaccinium (blueberry, cranberry and lingonberry; Ericaceae) are among the most important berry crop genera worldwide. Berry fruits are rich in vitamin C, cellulose, and pectin, and produce anthocyanins which have important therapeutic values, including antitumor,

Genetic Diversity, Erosion, and Population Structure in Cotton Genetic Resources
2015It is strongly believed that the wide genetic variability within the cotton (Gossypium spp.,) increases their chance for adaptation to changing harmful environments, and thus upsurge the likelihood of long-term survival of such unusual and important cash crop in the world.

Problems of genetic erosion in Transylvania, Romania
Die Kulturpflanze, 1981Started from the basic principles of IBP and MAB programmes, genetic resources of agricultural plant species cultivated traditionally in Transylvania have been studied. Land-races from this territory deserve special attention, as Transylvania is situated on the north-eastern border of the Mediterranian centre of diversity, between Near-East and Western

Coffee: Genetic Diversity, Erosion, Conservation, and Utilization
2021The predominantly cultivated coffee, Coffea arabica, is characterized by low genetic diversity making it highly vulnerable to biotic and abiotic stresses. The key to sustaining the coffee crop and the industry that depends on the crop will depend on the genetic diversity of the crop. In addition to the two cultivated species, C.
