Borlaug crossed plant varieties to achieve a genetically superior plant, now insect resistant genes, chemical resistant genes, and some environmental condition resistances are being inserted into the plant to increase their productivity.
Transgenic / Bt (Bacillus Thuringiensis) naturally occurring gene found in the soil that when ingested by insects (larvae) they are killed.
Most common planted Bt crops in the world are: Cotton, Maize, Soybeans, and Rice.
