Question

What do you understand by crop improvement and why is it necessary?

Answer 1

Crop improvement refers to the genetic alteration of plants to satisfy human needs. It is the traditional method. In prehistory, human forebears in various parts of the world brought into cultivation a few hundred species from the hundreds of thousands available. In the process they transformed elements of these species into crops through genetic alterations that involved conscious and unconscious selection, the differential reproduction of variants. To meet ever increasing demand for food, crop improvement can help to fulfil the demands.
