Current Roundup Ready crops include soy, corn (maize), canola, [2] sugar beets, [3] cotton, and alfalfa, [4] with wheat [5] still under development. Additional information on Roundup Ready crops is available on the GM Crops List. [6] As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. [7] [8]
In the United States, use of Roundup experienced rapid growth following the commercial introduction of a glyphosate-resistant soybean in 1996. [76] "Roundup Ready" became Monsanto's trademark for its patented line of crop seeds that are resistant to Roundup. Between 1990 and 1996 sales of Roundup increased around 20% per year. [77]
A genetically modified soybean is a soybean (Glycine max) that has had DNA introduced into it using genetic engineering techniques. [1]: 5 In 1996, the first genetically modified soybean was introduced to the U.S. by Monsanto. In 2014, 90.7 million hectares of GM soybeans were planted worldwide, making up 82% of the total soybeans cultivation area.
A 2003 study [117] concluded the "Roundup Ready" (RR) gene had been bred into so many different soybean cultivars, there had been little decline in genetic diversity, but "diversity was limited among elite lines from some companies". The widespread use of such types of GM soybeans in the Americas has caused problems with exports to some regions.
Farmers who plant such "Roundup Ready" crops are required to sign an agreement with Monsanto stipulating that they will buy new seeds from the company each year, rather than using the products of ...
Every Roundup Ready soybean in the world has a relative which was genetically transformed at Agracetus. 80% of the world's soybeans are Roundup Ready. Agracetus was founded in 1981 as Cetus Corporation.
Monsanto introduces genetically modified Roundup Ready soybeans that are resistant to Roundup (greatly improving a farmer's ability to control weeds, since glyphosate could be sprayed in the fields without harming their crops). [29] 1996: Acquisitions
In 1996, Asgrow released the first Roundup Ready Soybean to the market building upon Monsanto's work to create petunia plants tolerant to small amounts of Roundup developed by Robert Fraley in 1985. The first season of sales saw over 1 million acres using the new seed and quickly over 80% of US soybeans were produced with the seed. [6]
