Nepal's Seed Sector: SRR, Hybrid vs Improved Seed & SQCC Certification

A seed system is the whole chain that moves a crop variety from a plant breeder to a farmer's field: breeding, multiplication, quality control, marketing and distribution. In Nepal this chain has two parallel streams. The formal seed system produces, tests and sells officially released or registered varieties through public bodies, private companies and cooperatives, with quality guaranteed by certification. The informal system is farmer-to-farmer: seed saved from last harvest, exchanged with neighbours, or bought unlabelled in local markets.

The informal system still dominates staple food crops. Studies of Nepal's cereals estimate that the informal sector supplies more than 90 percent of the seed farmers actually plant, leaving the formal, quality-assured sector with under 10 percent. That imbalance is the central problem the country's seed policy is trying to fix, because seed saved and reused for many seasons gradually loses vigour, purity and yield potential.

Vegetables and hybrids tell a different story. Here farmers buy fresh packeted seed far more often, but much of it is imported. Understanding Nepal's seed sector therefore means understanding four things: the quality classes of seed, how SQCC certifies them, the seed replacement rate that measures how much fresh quality seed farmers use, and the gap between hybrid and improved seed.

Nepal follows the internationally recognised generation system of seed classes, each class being the direct progeny of the one above it. Nucleus and breeder seed sit at the top: breeder seed is produced under the direct supervision of the plant breeder or the originating institute (mainly the Nepal Agricultural Research Council, NARC) and is genetically and physically the purest. It is produced in very small quantities and is the source of every later generation.

Foundation seed is the progeny of breeder seed, multiplied under the supervision of the certification agency while keeping high genetic purity. Certified seed is the next generation, grown from foundation seed by registered seed growers and sold to farmers for commercial cultivation; it is produced in bulk and is the class most farmers encounter. Alongside these certified classes sits improved seed, often handled as truthfully labelled (TL) seed, where the producer guarantees the stated quality on the label rather than going through full field-and-lab certification. TL seed lets released varieties reach farmers faster while still carrying accountability for germination and purity.

The distinction matters for buyers. Certified seed has passed independent field inspection and laboratory testing; truthfully labelled seed relies on the producer's declared standards. Both are steps above unlabelled grain sold as seed, which carries no quality assurance at all.

The Seed Quality Control Centre (SQCC), based at Hariharbhawan, Lalitpur, is Nepal's national seed certification and quality-control authority under the Ministry of Agriculture and Livestock Development. SQCC serves as the secretariat of the National Seed Board, the country's apex seed policy body, and it houses the Central Seed Testing Laboratory. Its legal foundation is the Seeds Act, 2045 (1988) — authenticated on 26 October 1988 (2045.7.10 BS) — later amended and implemented through the Seed Regulation, 2069 (2013).

Certification is a step-by-step process: seed growers register with the certification agency, sow genetically pure source seed under prescribed isolation distances, and submit their fields to inspection at the seedling, flowering and pre-harvest stages. After harvest, samples are tested in the laboratory for germination, physical purity, moisture and freedom from other varieties. Only lots that pass every stage earn a certification tag.

Nepal's seed tags are colour-coded so a buyer can read the class at a glance (the beu tag rang, or seed-tag colour). Breeder seed carries a golden-yellow tag, foundation seed a white tag, and certified seed a blue tag, in line with widely used international conventions. Each tag also states the crop kind, variety, lot number, germination and purity percentages, and the producer's name and address. Checking the colour, the variety name and the test date on the tag is the simplest way for a farmer to confirm they are buying genuine quality seed.

The seed replacement rate (SRR) is the share of a crop's planted area sown with fresh quality (certified or improved) seed instead of farm-saved seed in a given season, expressed as a percentage. A higher SRR generally means healthier crops and better yields, because it limits the decline in vigour and purity that comes from reusing the same seed year after year. It is one of the headline indicators used to judge how modern a country's seed sector is.

Nepal's SRR for staple cereals is low. The National Seed Vision cites a baseline of roughly 15 percent for major cereals, and various field studies report figures ranging from single digits up to about 20 percent depending on crop and district, with wheat and rice usually ahead of maize and pulses. Vegetables are the exception: because farmers buy packeted seed each season, vegetable SRR was already reported around 66 percent as far back as 2009. The low cereal figures reflect the dominance of the informal seed system and limited farmer access to newly released varieties.

Raising the SRR is the practical goal behind much of Nepal's seed policy. Faster replacement depends on producing enough certified and foundation seed, getting new varieties released and registered quickly, and building village-level production so quality seed is available where farmers live rather than only in distant markets.

Improved (or open-pollinated) varieties are stable lines developed through conventional breeding and officially released; a farmer can save seed from the harvest and replant it for several seasons without losing the variety's identity. Hybrid seed is the first-generation (F1) cross of two distinct parent lines, bred to maximise vigour and yield. The catch is that saved hybrid seed does not breed true — the second generation segregates and yields fall sharply — so farmers must buy fresh hybrid seed every season.

That single difference shapes the market. Hybrids can lift yields substantially, which is why their use is rising fast in maize, rice and vegetables, but they lock farmers into repeat purchases and, in Nepal's case, into imports. Reporting has estimated that Nepal imports well over 90 percent of its vegetable seed and a large share of hybrid maize and rice seed, chiefly from India and China, worth billions of rupees each year; press coverage put 2018/19 vegetable-seed imports at about 424,000 kg worth roughly Rs 553 million. These figures move year to year and should be read as indicative rather than exact.

For farmers the choice is a trade-off. Hybrids can pay off through higher output where inputs and markets support them, while improved open-pollinated varieties are cheaper over time because seed can be saved, and they keep more of the seed supply inside the country. Nepal's policy aim is to build domestic hybrid breeding and production so the yield gains do not depend permanently on imports.

The National Agricultural Research Council (NARC) sits at the top of the chain, breeding and releasing new varieties and producing breeder and much of the foundation seed. National Seed Company Ltd (NSCL) — restructured as a dedicated seed enterprise around 2002 when the former Agriculture Inputs Corporation was split into separate seed and fertiliser bodies — is the main public multiplier and distributor of cereal seed, handling rice, wheat, maize, lentil, oilseed and other crops across the country.

Around these public bodies has grown a mix of private seed companies, agro-vet retailers and, increasingly, community-based seed production (CBSP) groups and cooperatives that multiply certified and truthfully labelled seed close to farmers. Private importers dominate the hybrid and vegetable-seed trade. The National Seed Board sets policy and approves variety release, while SQCC certifies quality across all these actors.

The persistent challenge is scale and reliability. Public seed production has faced capacity and financial strains, while private investment concentrates on the most profitable hybrid and vegetable segments rather than staple cereals. Closing the cereal seed gap depends on strengthening both public multipliers and decentralised community producers.

The National Seed Vision 2013-2025, published in 2013 (2070 BS) by what was then the Ministry of Agricultural Development, is Nepal's guiding seed-sector strategy. It sets out to build a competitive, sustainable and inclusive seed sector that raises quality-seed use, cuts import dependence and improves smallholder access to improved varieties. It is organised around a value-chain analysis and a set of measurable targets to be reached by 2025.

Its headline goals include lifting the seed replacement rate to 25 percent for cereal crops and about 90 percent for vegetables by 2025, expanding domestic production of hybrid seed, increasing the number of released and registered varieties, and moving toward self-sufficiency in the seed of major crops. For maize the Vision set an SRR target in the low thirties. Reviews of implementation have found progress uneven — several targets, especially for cereal SRR and hybrid self-sufficiency, remained behind schedule as the period closed.

As the 2025 endpoint passed, the Vision's core message still frames Nepal's seed debate: the country needs to produce more of its own quality seed, get it certified and tagged, and put it into far more farmers' hands than the informal system reaches today. Whatever succeeds it, those priorities — a higher SRR, credible SQCC certification, and home-grown hybrid capacity — remain the benchmarks for the sector.
