New Rices For Africa
New Rice for Africa ("NERICA") is a cultivar group of interspecific hybrid rice developed by the Africa Rice Center (AfricaRice) to improve the yield of African rice cultivars. Although 240 million people in West Africa rely on rice as the primary source of food energy and protein in their diet, the majority of this rice is imported. Self-sufficiency in rice production would improve food security and aid economic development in West Africa. The results of the NERICA Project, which is funded by the African Development Bank, the Japanese government, and the United Nations Development Programme, was a major agenda item at the Fourth Tokyo International Conference on African Development (TICAD-IV) in 2008. The new rice varieties, which are suited to drylands, were distributed and sown on more than 200,000 hectares during the last five years in several African countries, notably Guinea, Nigeria, Mali, Benin, Côte d'Ivoire, and Uganda, according to the Africa Rice Center.

System Of Rice Intensification
A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences. Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity. Etymology The term ''system'' comes from the Latin word ''systēma'', in turn from Greek ''systēma'': "whole concept made of several parts or members, system", literary "composition"."σύστημα" Henry George Liddell, Robert Scott, '' |
World Food Prize
The World Food Prize is an international award recognizing the achievements of individuals who have advanced human development by improving the quality, quantity, or availability of food in the world. Conceived by Nobel Peace Prize laureate Norman Borlaug and established in 1986 through the support of General Foods, the prize is envisioned and promoted as the Nobel or the highest honors in the field of food and agriculture. It is now administered by the World Food Prize Foundation with support from numerous sponsors. Since 1987, the prize has been awarded annually to recognize contributions in any field involved in the world food supply, such as animal science, aquaculture, soil science, water conservation, nutrition, health, plant science, seed science, plant pathology, crop protection, food technology, food safety, policy, research, infrastructure, emergency relief, and poverty alleviation and hunger. Laureates are honored and officially awarded their prize in Des Moines, Iow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monty Jones
Monty Jones (born February 5, 1951) is a plant breeder and the Minister of Agriculture, Forestry and Food Security of Sierra Leone. He previously held the position of Special Adviser to the President of Sierra Leone and Ambassador-at-large until his appointment to cabinet. He is the immediate past Executive Director of the Forum for Agricultural Research in Africa (FARA) and co-winner of the 2004 World Food Prize. He won the award based on his discovery of the genetic process to create the New Rice for Africa (NERICA), which gives higher yields, shorter growth cycles and more protein content than its Asian and African parents. Biography Born Monty Patrick Jones on February 5, 1951, in Freetown, Sierra Leone, Jones was raised in a middle-class Creole Catholic family. He obtained a B.Sc. in Agriculture from Njala University College, University of Sierra Leone in 1974, followed by an M.Sc. in Plant Genetic Resources (1979) and a Ph.D. in Plant Biology (1983) from the University of ...

Heterosis
Heterosis, hybrid vigor, or outbreeding enhancement is the improved or increased function of any biological quality in a hybrid offspring. An offspring is heterotic if its traits are enhanced as a result of mixing the genetic contributions of its parents. These effects can be due to Mendelian or non-Mendelian inheritance. Definitions In proposing the term heterosis to replace the older term heterozygosis, G.H. Shull aimed to avoid limiting the term to the effects that can be explained by heterozygosity in Mendelian inheritance. Heterosis is often discussed as the opposite of inbreeding depression, although differences in these two concepts can be seen in evolutionary considerations such as the role of genetic variation or the effects of genetic drift in small populations on these concepts. Inbreeding depression occurs when related parents have children with traits that negatively influence their fitness largely due to homozygosity. In such instances, outcrossing shoul ...

Plant Tissue Culture
Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation. Different techniques in plant tissue culture may offer certain advantages over traditional methods of propagation, including: * The production of exact copies of plants that produce particularly good flowers, fruits, or have other desirable traits. * To quickly produce mature plants. * The production of multiples of plants in the absence of seeds or necessary pollinators to produce seeds. * The regeneration of whole plants from plant cells that have been genetically modified. * The production of plants in sterile containers that allows them to be moved with greatly reduced chances of transmitting diseases, pests, and pathogens. * The production of plants from seeds that otherwise have very low chances of germinating an ...

Oryza Sativa
''Oryza sativa'', commonly known as Asian rice or indica rice, is the plant species most commonly referred to in English as ''rice''. It is the type of farmed rice whose cultivars are most common globally, and was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago. ''Oryza sativa'' belongs to the genus '' Oryza'' of the grass family Poaceae. With a genome consisting of 430 Mbp across 12 chromosomes, it is renowned for being easy to genetically modify and is a model organism for the botany of cereals. Classification ''Oryza sativa'' contains two major subspecies: the sticky, short-grained ''japonica'' or ''sinica'' variety, and the nonsticky, long-grained ' rice variety. ''Japonica'' was domesticated in the Yangtze Valley 9–6,000 years ago, and its varieties can be cultivated in dry fields (it is cultivated mainly submerged in Japan), in temperate East Asia, upland areas of Southeast Asia, and high elevations in South Asia, while ''indica'' w ...

Blast Disease
''Magnaporthe grisea'', also known as rice blast fungus, rice rotten neck, rice seedling blight, blast of rice, oval leaf spot of graminea, pitting disease, ryegrass blast, Johnson spot, neck blast, wheat blast, and Imochi (Japanese:稲熱) is a plant-pathogenic fungus and model organism that causes a serious disease affecting rice. It is now known that ''M. grisea'' consists of a cryptic species complex containing at least two biological species that have clear genetic differences and do not interbreed. Complex members isolated from ''Digitaria'' have been more narrowly defined as ''M. grisea''. The remaining members of the complex isolated from rice and a variety of other hosts have been renamed ''Magnaporthe oryzae'', within the same ''M. grisea'' complex. Confusion on which of these two names to use for the rice blast pathogen remains, as both are now used by different authors. Members of the ''Magnaporthe grisea'' complex can also infect other agriculturally important cereal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rice Yellow Mottle Virus
Rice yellow mottle virus (RYMV) is a plant pathogenic virus, belonging to the genus Sobemovirus. The genome is a positive-sense single strand RNA of 4450 nucleotides in length and is not polyadenylated. It was first reported in Kenya in 1966 in one of Africa's first cultivation intensification schemes, due to RYMV's association with intensification,p.7, "RYMV was first detected in 1966 near Kisumu in Kenya along the north-east shore of Lake Victoria 1 This report coincided with the development of one of the first major intensive rice production schemes in Africa. Since then, most epidemics have been associated with rice intensificiation." but DNA analysis of its evolutionary history shows it to have evolved in East Africa in the 19th century.Abstract, "Diversification and spread of RYMV has been concomitant with an extension of rice cultivation in Africa since the 19th century."Abstract, "In East Africa, RYMV emerged in the 19 century after rice intensification along the Indian ...
