Paperback. Zustand: New. Print on Demand. This book analyzes the advent of semi-dwarf, high-yielding varieties of wheat and rice developed in Mexico and the Philippines, detailing their spread in statistical terms since the mid-1960s. The author describes their origins, tracing the developments in Japan, Italy, and the US that resulted in the Mexican varieties, which, in turn, influenced the development of the IRRI varieties. The book also covers other varieties, including those from national programs in India, Thailand, and Taiwan. It is shown that most of the semi-dwarf varieties are grown under irrigated conditions, and some attention is given to the need for drought-resistant varieties, particularly in the drier climates in which wheat is primarily grown. The book highlights the significant impact of these new varieties on the worldâs food supply, particularly in developing nations.
