... After soybean, transgenic cotton is the foremost commercially successful biotech crops. In 1996, Monsanto with Delta and Pineland Co. (D&PL) commercially released two transgenic cotton varieties (NuCOTN 33 and NuCOTN 35 ) with a trademark Bollgard™ for general cultivation [71]. Introduction of Bt cotton nearly doubled the lint yield by minimizing production losses due to the infestation of bollworm complex. ...
