Correct Answer - A
Conventional plant breeding results in open pollinated varieties (OP) or hybrid varieties which has a tremendous impact on agriculture productivity over the last decades. Conventional plant breeding also has its limilations. First, breeding can only be done between two plants that are sexually compatible with each other. This limits the new traits that can be added to those that already exist in a particular species. Second, when plants are crossed, many traits that have undersirable effects on potential yield are transferred along with the traits/s of interset.
