Enhancing the Conservation of Crop Wild Relatives in England
Humans require resilient, rapidly renewable and sustainable supplies of food and many other plant-derived supplies. However, the combined effects of climate change and population growth compromise the provision of these supplies particularly in respect to global food security. Crop wild relatives (CWR) contain higher genetic diversity than crops and harbour traits that can improve crop resilien...
متن کاملBack into the wild—Apply untapped genetic diversity of wild relatives for crop improvement
Deleterious effects of climate change and human activities, as well as diverse environmental stresses, present critical challenges to food production and the maintenance of natural diversity. These challenges may be met by the development of novel crop varieties with increased biotic or abiotic resistance that enables them to thrive in marginal lands. However, considering the diverse interactio...
متن کاملCassava, Manihot esculenta Crantz, genetic resources: origin of the crop, its evolution and relationships with wild relatives.
About 98 species of Manihot are known. All of them are native to the New World and are concentrated in four regions in Brazil and Central America. All the Manihot species so far examined have 2n = 36 chromosomes. Interspecific hybrids between cassava and its wild relatives show relatively normal meiosis, and further generations can be obtained. Electrophoresis shows affinity among wild species ...
متن کاملFlora and Vegetation of Afghanistan
Afghanistan is a very mountainous country. It offers a big variety of ecological conditions, this means a big variety of vegetation types is covering land surface. These vegetation types are consisting of a high biodiversity, since the floristic influence from various neighbour regions is a considerable factor in floristic and vegetation pattern. On the other hand, Afghanistan is a very dry cou...
متن کاملConservation of allelic richness in wild crop relatives is aided by assessment of genetic markers.
Wild crop relatives are an important source of genetic variation for improving domesticated species. Given limited resources, methods for maximizing the genetic diversity of collections of wild relatives are needed to help spread protection over a larger number of populations and species. Simulations were conducted to investigate the optimal strategy of sampling materials from populations of wi...
