Improved Seeds and Green Revolution

The purpose of this review is to share with developing countries how a dedicated agricultural university helped enhance food production 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, efficient 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 revolutionary 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 biotechnology, 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 the production of hybrid seed and nursery help boost seed production and farmers' income. The seed-plot technique in potato and rhizobium inoculation of pulse seeds have had a strong impact on production. The supply of high-quality mushroom spawn and quality Kinnow (citrus) plantlets to farmers has boosted mushroom and citrus production, and thereby the farmers' incomes. Ever-increasing population requires universities, such as PAU, to continue to play pivotal roles in enhancing food production. Seed production programs will need to be put on a new trajectory to double food production by 2050 and agricultural universities would need to be strengthened to meet this critical goal.
