What is the breeding of corn?
Corn breeding is an attempt at genetically and ecologically increases corn crops so that they are more resistant to disease and pests, more productive and more tolerant to unfavorable weather conditions. Corn is a type of grain produced for human consumption in many forms and as a source of oil. In the US, corn is most often referred to as sweet corn, Indian corn or maize, and these concepts specify varieties cultivated for human food. Other maize varieties are also grown for feeding livestock and for other commercial purposes, such as the production of corn syrup with a high fructose content as a substitute for sugar or fuel ethanol. The trunks are often divided into the level of starch, which everyone has, and high varieties of starch are grown for popcorn, such as zea mayys var. Everta and lower varieties of starch, which are ground into corn flour roast goods such as zea mayys var. Amylacea . Programs of selective breeding of maize hybrids and geneticThe species engineering for the production of strong and resistant strains takes place in many places throughout Europe, the UK and the US.
plant breeding is an international interest in cereal crops such as corn. The reason is that grains are such a large part of the everyday diet for human and animal, and corn breeding is an attempt to provide a world offer because illnesses and pests adapt to its growth. Two other primary areas in the breeding of maize are drought tolerance and nitrogen resistance due to the growing use of concentrated nitrogen fertilizers. This effort has led to the fact that the worldwide production of maize has overtaken all other grains, with planned levels since 2011 of 858,000,000 tons compared to 666,000,000 tonnes produced and 448,000,000 tons of rice.
maize crops are considered as important to map the entire race genome in 2008 by three AmericanMi Agencies, National Science Foundation (NSF), the US Department of Agriculture (USDA) and the Ministry of Energy (Doe), which have all the share of ensuring corn crops. This genetic map of 32,540 genes was publicly made available online for international research. The ultimate goal to understand the genetics of corn is to find a way to prevent damage to crops, such as the fungus fusarium verticiliodes , causing the gnoming of corn core. Mushrooms produce fumonism, mycotoxin so potentially harmful to humans and animals that similar mushroom compounds were involved in the cases of yellow rain, where they are suspected of being used as war weapons in Afghanistan at the beginning of the 80s.
The US and other North American countries Mexico and Canada are on corn as their primary grain plot, so that maize breeding gains much attention. This area of the world produces about half of the world's maize offer. However, most of this production is not aimed at deliveryHuman food. In 2009, 333,000,000 tons of corn was grown in 2009. The US exports about 24% of its total grain production, while 6% is used for direct human consumption consumption, 32% goes into industrial use and 29% for livestock feed. The remaining 74,700,000 tonnes of grain surplus in the US in 2010 took place as reserve shares.
