Crop wild relatives in the Pampas

Botanical Journal of the Linnean Society
Abstract The average global temperature is expected to rise in the coming years, demanding more resilient crops. Crop wild relatives (CWR) are critical for assisting in the development of resistant cultivars to various biological and abiotic stresses, as well as increasing productivity and providing environmental, economic, and social

Importance of Crop Wild Relatives

2019
In a plant evolutionary time scale, running to millions of years, with a very constrained genetic bottleneck in the selection of rare mutations for domestication traits (reduced shattering, reduced seed dormancy, and increased seed size) and natural selection under a generally mild environment without frequent extremes, crop diversification during the ...

Towards a definition of a crop wild relative

Biodiversity and Conservation, 2006
Crop wild relatives are an important socio-economic resource that is currently being eroded or even extinguished through careless human activities. If the Conference of the Parties (COP) to the CBD 2010 Biodiversity Target of achieving a significant reduction in the current rate of loss is to be achieved, we must first define what crop wild relatives ...

Conservation of Crop Wild Relatives in the USA

2018
Crop wild relatives (CWR) are found throughout the USA, with a high concentration in the eastern part of the country. These wild plants include the ancestors of crops domesticated within the borders of the country, such as sunflower, pecan, blueberry, cranberry, and squash, as well as the relatives of crops domesticated elsewhere. This chapter presents

The Threats to Crop Wild Relatives

2019
In addition to climate change, there are several other threats to CWRs, such as, their loss, degradation, and fragmentation of their natural habitats, deforestation, logging, plantation and industrialized agriculture, forestry, dryland destruction and desertification, fire, urbanization, mining and quarrying, and, massive invasive species.

Crop wild relatives and climate change.

2014
Abstract This chapter provides an analysis of the importance of crop wild relatives (CWR) in plant breeding and the need for their comprehensive conservation. The importance of CWR diversity as a potentially critical resource for future food security is now widely recognized, particularly in the light of climate change and the rapidly ...

Collecting the Wild Relatives of Crops in the Tropics

2012
There remains much that is not known about wild relatives of major crops. Hence the need for further collecting and study of these wild genetic resources is warranted. In recent years international and legal aspects of collecting and using germplasm have changed and need to be considered carefully in the preparatory phase of collecting.

A crop wild relative inventory for Brazil

Crop Science
Abstract Crop wild relatives (CWRs) are defined as wild plant taxa that are closely related to agricultural crops. In the face of global pressures of climates change and biodiversity loss, CWR requires urgent conservation attention.

The DNA of Crop Plants and their Wild Relatives

1986
ABSTRACT Closely related species may differ widely both in the amount of total DNA and in the organisation of the DNA sequences within the genome. Examples of these kinds of differences among crop plants and their relatives are presented, and an attempt is made to evaluate the significance of such variation.

Using crop wild relatives as sources of useful genes.

2007
Wild plant genetic resources (PGR), and particularly crop wild relatives, represent a source of useful germplasm for the present and future generations. In the past, the majority of the information on PGR was based on phenotype, geographic origin, social history, and parentage In the last decades, advances in plant science and technology have provided ...
