During the late 1950s and early 1960s food deficits India has been requiring importation of 3 to 4 million tons of grain per year. However because of bad monsoons in 1965 and 1966, imports exploded unpwardly to 10 million tons, and India was in dire straits. It was during this period that, after three years of testing on experiment stations, the so-called high yielding Mexican wheat varieties, which had proven very interesting under experimental conditions, where considered as a possible way to break the worsening food deficit.
