The purpose of this review is to share with developing countries
how a dedicated agricultural university helped enhance food pro-
duction and thwart Malthusian scenario. The Indian adequacy
on the food-front has largely been attributed to the development of
improved seeds of different crops, in particular wheat and rice, effi-
cient system of agro-technology generation and its transfer to farmers,
and useful coordination between state development departments
and suitable government policies. We have discussed the revolution-
ary role of Punjab Agricultural University (PAU) in transforming a
food-deficient India into a food self-sufficient nation. This dramatic
transformation is dubbed the Green Revolution. Fueled by scientific
research, PAU has, since its inception in 1962, released more than
580 improved varieties/hybrids of field crops, vegetables, fruits,
fodder, and ornamentals. Now, almost the entire cropped area of
the Punjab state is under improved varieties. This is because PAU
has one of the best seed-production and delivery programs among
agricultural universities in India. Its total seed production capacity
during the last five years was >30,000 tons. Millions of disease-free
nursery plants of fruits and ornamentals are supplied to farmers
annually. The seed-production technology, together with an improved
seed-distribution system, has given an impetus to agriculture in recent
years. New breeding methods and modern technologies, such as bio-
technology, electron microscopy, and nanotechnology, should provide
even better seeds in the future. The scanning electron microscopy
facilities at PAU have helped distinguish between seed surfaces of
drought-resistant and drought-susceptible genotypes of Indian
mustard, and, revealed that seed coat microstructure could be
used as a selection criterion for stress tolerance. Farmer training in
