Impact of Improved and Certified Seeds on Indian Agriculture

India was once heavily dependent on food imports to feed its growing population. By the mid-1960s, the country faced recurring food shortages and famines that threatened millions of lives. What changed this trajectory was not just better irrigation or more farmland – it was the seed. The introduction of high-yielding variety (HYV) seeds, particularly for wheat and rice, triggered one of the most dramatic agricultural transformations in modern history, turning India from a food-deficit nation into one of the world’s largest agricultural producers.

India before improved seeds: a nation on the edge 🔗

Before the Green Revolution took hold, Indian agriculture was defined by traditional farming practices and low-yielding indigenous crop varieties. Food availability in India during the early post-independence decades was only about 417 grams per person per day, with many farmers deeply in debt and unable to sustain their households. In 1964-65 and 1965-66, two consecutive droughts pushed the country to the brink, making it clear that traditional methods alone could not meet the demands of a rapidly growing population. The government needed a fundamentally different approach to agricultural productivity – and that approach came in the form of improved seeds.

The Green Revolution and the rise of high-yielding varieties 🔗

The Green Revolution in India formally began in the late 1960s under the guidance of geneticist Dr. M.S. Swaminathan, widely recognised as the “father of the Green Revolution” in India. He collaborated with Nobel Prize-winning agronomist Norman Borlaug to introduce new Mexican wheat varieties that had been developed at the International Maize and Wheat Improvement Centre (CIMMYT). These were not ordinary seeds – they were short-stemmed, disease-resistant, fast-maturing, and highly responsive to fertilizers.

In 1966, India imported 18,000 tons of these new Mexican wheat seeds, which dramatically altered wheat production, particularly in the northwestern states of Punjab and Haryana. The results were immediate and striking – wheat output surged from 12 million tons in 1965 to 20 million tons by 1970. By 1971, India had achieved self-sufficiency in food production, and by the late 1970s it had become one of the world’s leading agricultural producers.

Rice production followed a similar path. India adopted IR8, a hybrid high-yield and pest-resistant rice strain developed at the International Rice Research Institute (IRRI) in the Philippines. Research showed that IR8 rice could yield around 5 tonnes per hectare without fertilizer, and nearly 10 tonnes per hectare under optimal conditions – a massive leap over what traditional varieties could produce.

What makes a seed “improved” or “certified”? 🔗

Not all seeds are equal. In agricultural policy, there is an important distinction between farm-saved seeds, improved seeds, and certified seeds – and understanding this distinction is central to appreciating India’s seed revolution.

Improved seeds 🔗

Improved seeds refer to varieties developed through scientific breeding programs to deliver superior performance – higher yield potential, resistance to pests and diseases, tolerance to drought or flooding, and better grain quality. Breeding programs selected for higher yield potential, wide adaptation to diverse environments, short growth duration, superior grain quality, and resistance to both biotic and abiotic stress. These are the seeds that formed the backbone of India’s Green Revolution.

Certified seeds 🔗

Certified seeds take the concept of improved seeds a step further by adding a formal quality assurance process. They undergo rigorous testing and quality control, guaranteeing genetic purity, germination rates, and freedom from seed-borne diseases. The Seeds Act of 1966, along with subsequent amendments, regulates the production and sale of certified seeds in India. Under this framework, seeds pass through a structured chain – from breeder seed to foundation seed to certified seed – before reaching a farmer’s hands. Each stage involves field inspections, isolation requirements to prevent cross-pollination, and laboratory testing to verify quality standards.

The Indian seed system recognises three generations in its multiplication chain: breeder seed, foundation seed, and certified seed. This tiered approach ensures that the genetic integrity of high-performing varieties is preserved as seeds are multiplied at scale for distribution across the country.

The National Seeds Corporation: India’s seed backbone 🔗

A key institution in making improved and certified seeds accessible to India’s millions of farmers has been the National Seeds Corporation (NSC), founded in March 1963 as a government undertaking under the Ministry of Agriculture and Farmers Welfare. Its mandate was straightforward but enormously consequential: develop India’s seed industry on a sound footing and ensure farmers have access to quality planting material.

NSC currently produces certified seeds of nearly 600 varieties of 60 crops through about 8,000 registered seed growers spread across different agro-climatic conditions in the country. This extensive network allows the corporation to cater to regional diversity – from the wheat belts of Punjab to the rice paddies of West Bengal.

The corporation also plays a critical role during crises. The SAARC seed bank maintained by NSC, with grant-in-aid from the Government of India, holds large quantities of seeds of different crops and varieties meant to meet demand during natural calamities like floods and droughts. This emergency reserve function ensures that a bad monsoon or a disaster year does not set back agricultural progress for an entire season. NSC has actively participated in major national programs including the Green Revolution, the National Food Security Mission (NFSM), and the Bringing Green Revolution to Eastern India (BGREI) initiative.

Quality control is central to NSC’s operations. The corporation has established quality control laboratories in New Delhi, Secunderabad, Bhopal, Kolkata, and Pune to undertake seed testing and verify quality before seeds reach farmers.

Impact on crop productivity and food security 🔗

The cumulative impact of improved and certified seeds on India’s agricultural output has been profound. After the Green Revolution, the production of cereal crops tripled globally with only a 30% increase in cultivated land area. In India specifically, the shift to HYV seeds converted a chronically food-deficient country into a nation capable of feeding itself – and then some.

Wheat production surged to 55 million tonnes in the early years of the plan, a figure that would have been unimaginable just a decade earlier. The use of quality seed alone can increase productivity by 15 to 20%, making it one of the most cost-effective investments a farmer can make. When combined with proper irrigation, fertilizers, and agronomic practices, the gains are multiplied further.

Studies have found that high-yield crop varieties reduced infant mortality in India, with particularly large effects for rural children and low-income households – a powerful reminder that agricultural productivity improvements have direct human welfare consequences that go far beyond farm income statistics.

Regional concentration and its limits 🔗

The benefits of improved seeds were not uniformly distributed across India. The Green Revolution spread primarily in irrigated and high-potential rain-fed areas, leaving out villages and regions without access to sufficient water. States like Punjab, Haryana, and Uttar Pradesh – with strong irrigation infrastructure – reaped the greatest rewards, while rain-dependent states lagged behind. This regional disparity between adopters and non-adopters became one of the defining criticisms of the first Green Revolution era.

Additionally, the cost of HYV seeds, along with their associated demands for fertilizers and irrigation, placed a financial burden on small and marginal farmers who often lacked the capital or credit access to participate fully in the seed revolution.

Government policy: building the seeds ecosystem 🔗

India’s seed sector is supported by an evolving policy framework designed to ensure both quality and accessibility. Policy initiatives taken by the Government of India during the 1960s and 1970s for generating quality seed production and distribution of improved plant varieties developed by scientists is one of the primary reasons for India’s self-sufficiency in food grains.

The Seeds Act of 1966 created the foundational legal structure, establishing voluntary seed certification and compulsory labelling standards. State Seed Certification Agencies (SSCAs) in each state are responsible for field inspections and seed tests required for certification, while the Central Seed Certification Board advises state governments on certification standards. This decentralised architecture ensures that quality assurance is grounded in local conditions.

The New Seed Policy of 1988 marked another turning point by liberalising seed imports under an Open General License, permitting the import of seeds of oilseed crops, pulses, coarse grains, vegetables, and flowers to make high-quality seeds available to farmers and maximise yield. This policy invited private sector investment into the seed industry and accelerated the development of hybrid varieties – particularly for crops like cotton, maize, and vegetables.

More recently, the Department of Agriculture and Farmers Welfare has been implementing a central scheme for the development and strengthening of infrastructure facilities for production and distribution of quality seeds, with the specific aim of reaching farmers in remote areas not easily accessible by road or rail. The Protection of Plant Varieties and Farmers’ Rights (PPV&FR) Act, 2001 added another layer by protecting the rights of both commercial plant breeders and farmers to save, use, and exchange their traditional seed varieties.

Challenges and the road ahead 🔗

Despite the impressive progress, India’s seed sector faces significant ongoing challenges. India’s seed quality assurance system and certification standards are considered lower than global benchmarks and need strengthening to match international norms. The informal seed system still contributes about 65% of India’s total seed supply, meaning a large proportion of farmers continue to rely on farm-saved or locally exchanged seeds of variable quality – a gap that formal certified seed programs have yet to fully bridge.

Climate change adds another layer of urgency. Organisations like CIMMYT have been working with Indian partners to develop and distribute climate-resilient seed varieties capable of withstanding higher temperatures – a critical need as heat waves increasingly threaten wheat and other cereal yields in states like Punjab and Haryana. The next generation of improved seeds will need to deliver not just high yields but also resilience in the face of extreme weather.

There is also the question of crop diversity. The Green Revolution’s focus on wheat and rice resulted in a significant decline in the cultivation of millets, lentils, and other traditional crops, narrowing both agricultural biodiversity and dietary diversity in India. Current policy efforts around millets and nutri-cereals represent a course correction – an attempt to bring improved seeds and certified varieties to a broader range of crops beyond the rice-wheat corridor.

Quality seed as the foundation of food security 🔗

What India’s experience makes clear is that the seed is not merely the starting point of a crop cycle – it is the foundation upon which an entire food system is built. The shift from traditional, farm-saved seeds to scientifically improved and certified varieties transformed not just yields but the entire structure of Indian agriculture. It enabled a country of over a billion people to feed itself, reduced rural poverty in key regions, and built the institutional infrastructure – from the NSC to state certification agencies – that continues to underpin agricultural productivity today.

The work is far from complete. Reaching small and marginal farmers in rain-fed regions, raising certification standards, expanding the range of improved varieties beyond rice and wheat, and developing climate-resilient seeds for a warming world are all tasks that demand continued investment and policy attention. But the foundational lesson from six decades of India’s seed revolution remains as valid as ever: put the right seed in the ground, and the rest becomes possible.

What do you think? Given that the informal seed system still accounts for a large share of India’s seed use, what policy measures could most effectively bring small and marginal farmers into the certified seed ecosystem? And as climate change intensifies, should India’s seed development priorities shift significantly toward stress-tolerant varieties over high-yield ones – or can both goals be achieved together?
