Genetically modified crops are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species. As of 2015, 26 plant species have been genetically modified and approved for commercial release in at least one country. The majority of these species contain genes that make them either tolerant to herbicides or resistant to insects. Other common traits include virus resistance, delayed ripening, modified flower colour or altered composition. In 2014, 28 countries grew GM crops, and 39 countries imported but did not grow them.

In 2014, 181.5 million hectares of genetically modified crops were planted in 28 countries. Half of all GM crops planted were genetically modified soybeans, either for herbicide tolerance or insect resistance. Eleven countries grew modified soybean, with the USA, Brazil and Argentina accounting for 90% of the total hectarage. Of the 111 hectares of soybean grown worldwide in 2014, 82% was genetically modified in some way. Seventeen countries grew a total of 55.2 million hectares of genetically modified maize and fifteen grew 23.9 hectares of genetically modified cotton. Nine million hectares of genetically modified canola was grown with 8 million of those in Canada. Other GM crops grown in 2014 include Alfalfa (862 000 ha), sugar beet (494 000 ha) and papaya (7 475 ha). In Bangladesh a genetically modified eggplant was grown commercially for the first time on 12ha.[6]

The majority of GM crops have been modified to be resistant to selected herbicides, usually a glyphosate or glufosinate based one. In 2014, 154 million hectares were planted with a herbicide resistant crop and 78.8 million hectares had insect resistant. This include 51.4 million hectares planted in thirteen countries that contained both herbicide tolerance and insect resistance. Less than one million hectares contained other traits, which include providing virus resistance, delaying senescence, modifying flower colour and altering the plants composition. Drought tolerant maize was planted for just the second year in the USA on 275 000 hectares.[6]

Rhe genitically modified plants has higher resistance to the unfavourable climatic conditions and also many deseases. And also leads to the higher productions as compared to others.
