Tropical Crops: The Origins of The Cassava

Linguistic evidence of cassava is widely accepted, occurring in the east of Peru, central and western part of Brazil. Tu Brown and his colleagues did Paleobiolinguistic (Brown 2013) to determine when and where cassava became important in some indigenous communities of prehistoric indigenous peoples. Several major original languages ​​are observed in the two major regions of Central America and South America. The cassava term was examined for each source language and the subject matter similarity of the language was determined by calculation.

Botanical evidence Cassava is widely considered to be the least understood among all major tropical crops (Allem 1994). In 1982, the growth of wild Manihot was observed in Goias province in Brazil, its form was very similar to that of M. esculenta, and the conclusion that cassava grew in the wild was derived (Hillocks 2002). - In his novel, writer Claude Mackay has studied how class concepts work in the world ruled by capitalism and colonialism. His protagonist is a rare black intellectual in society and can find symbols and inspiration in the most complex works of classical writers and the spirit of the simplest black people, but in finding their own position in society It is difficult.

Cassava is one of the most important food security crops in tropical countries and it is a competitive resource for starch, food, feed and ethanol industry. However, compared with other economically important crops such as rice and maize, crops are doing much less genomics research. The International Tropical Agriculture Center (CIAT) has the world's largest cassava germplasm resources. Unfortunately, due to the difficulty of phenotypic screening and the lack of deep genomic information on different germplasm, the genetic potential of this diversity in breeding programs is not fully utilized. This year, the chromosome horizontal assembly of the cassava reference genome was released and there were only few studies done to find quantitative trait loci (QTL) of breeding populations with limited variability.

Maize and potatoes have the world's greatest historical importance for American crops, but smaller crops are also crops. In West Africa, peanuts and cassava offer new food. Cassava is a tropical bush native to Brazil and has starch roots that can grow in almost every soil. Cassava is an indispensable crop in soils in West Africa and Central Africa. Today, about 200 million Africans trust it as a major nutrition source. Cocoa and rubber are two other South American crops that became important exports to West Africa in the 20th century. Sweet potatoes introduced in China in the 1960s became the third largest crop in China after rice and wheat. It has proven to be a useful supplement to the diet of the Asian monsoon region in Asia. Indeed, in almost every other part of the world, it is less likely that one or more American food crops will be captured, supplementing existing crops, or replacing them. Without them, the increase in the modern population will certainly be delayed.
