Abstract: The production of high-yielding varieties of wheats in developing countries in recent years has been so successful as to be termed a Green Revolution. These wheats (semidwarfs), originating in Mexico, are short stemmed, photo insensitive, and highly responsive to inputs. Total semidwarf wheat area in India, Pakistan, Mexico, Turkey, Afghanistan, Tunisia, Iran and Morocco, expanded rapidly from 0.6 million hectares in 1966 to 10.6 million hectares in 1970. Production during the same period increased from 1.6 million tons to 22.7 million tons. In 1970, semidwarf wheat in these countries accounted for 25 percent of the total wheat area and 49 percent of the total wheat output. This agricultural advance is attributed to programs developed by individual governments with the assistance of international institutions and private agencies.
