“…Production cost is also a significant influencing factor; greater production costs may prompt seed companies to opt for the production of lower-cost substandard seeds. Governmental rewards and penalties also affect company decisions 33 . The encouragement for the production of high-quality seeds can be fostered by amplifying rewards, whilst the deterrence of seed companies from unlawful activities can be achieved by intensifying penalty measures.…”

Seeds, as the initial products in agricultural systems, play a pivotal role in ensuring quality, fundamental to national food security and sustainable agricultural development. This study introduces a concept integrating public governance and evolutionary game theory to construct a quadripartite evolutionary game model involving seed companies, certification agencies, farmers, and governmental departments. It considers the strategic choices of these stakeholders under varying economic motivations and market mechanisms, as well as the influence of external regulation and incentives on game strategies. The existence conditions for evolutionarily stable strategy combinations are determined using the Lyapunov first method, and MATLAB is employed for numerical simulation analysis to validate the game analysis under initial conditions. The simulation results reveal two potential equilibrium points corresponding to different strategic choices among stakeholders. The study finds that producing high-quality seeds and the refusal of certification agencies to engage in rent-seeking are crucial for ensuring seed quality. Additionally, the cost-benefit ratio of seed companies, the speculative cost of certification agencies, and the rights-protection cost of farmers are key determinants in the evolution of seed quality assurance strategies. This research also holds practical significance in enhancing seed quality assurance mechanisms and fostering sustainable development in agriculture.

“…The varieties developed are not preferred by urban consumers. Emphasis has been laid to breed varieties demanded by urban and rural consumers taking into account the needs of diverse farming households in poor countries (Donovan et al, 2021; Mausch et al, 2021). Therefore, Africa has to go a long way in developing high-yielding varieties comparable to the varieties developed in Asia.…”

The growth in rice consumption has either slowed down or become negative in all the continents although additional per capita demand for rice exists in Africa. The future additional rice demand will mainly come from the population growth in Africa and Asia. The production growth during the past led by growth in yield has helped in meeting rice demand around the globe. However, Africa continues to lag far behind other continents in achieving the desired level of yield. Additional research efforts are needed in all continents for the production of varieties with higher yield potential and desired grain quality with more emphasis on the African continent. The global demand for rice will be about 584 million tons or less towards 2050. With positive technological developments in the rice research arena, the shape of rice agriculture will change towards 2050. Asia may lose about 5 million ha and Africa gain about 10 million ha of rice land by 2050.

“…Yet, public records are not available on the demands raised by the extension departments or GOI to produce BS seeds in 84 privately owned F 1 hybrids. Reliable data on seed sales and uptake by cultivar type in developing regions remain very scarce (Donovan et al 2021). It is important to review and correct this skewed public-private partnership to foster harmonious relations and data sharing between the two partners.…”

Impact of breeder seed multiplication and certified quality seed distribution on rice production in India

Background The All India Coordinated Rice Improvement Project (AICRIP) organizes multi-location tests (METs) with new genotypes from breeding programs. The best performing genotypes in METs for 3–4 years are identified and notified as commercial cultivars by the Government of India (GOI) to authorize breeder seed (BS) production. Methods We created a database and analyzed data on BS production for 24 years (1995–96 to 2018–19) in 475 inbred and 22 F1 hybrid cultivars. Estimates were made to rank cultivars on the proportional contribution of a cultivar, quantity produced and a new BS index. Correlation and regression analyses were used to find the relationships between BS, certified quality seed distributed (CQSD), and milled rice production. We compared cultivars in BS production chain with those grown in farmers’ fields across the country as identified in the production-oriented surveys. Results The top ten inbred cultivars identified are Jaya (notified by GOI in 1969), Swarna, Kranthi, IR 36, Sarjoo 52, Samba Mahsuri and Pusa Basmati 1 (notified in 1980–1989), and IR 64, Vijetha and Cottondora Sannalu (notified in 1991–2000). BS production in hybrid F1 was insignificant. We detected a Pearson correlation (r = 0.806, P < 0.01) between the BS production and CQSD, and a linear relationship between the annual rice production in India and the CQSD (R2 = 0.850, P < 0.01). The rice area coverage in 2018–19 with CQSD estimated was 41%. A total of 1877 cultivars (528 notified and 1349 not notified) were found at farms in rice growing districts in India. Conclusions From 1995–2019, BS and CQSD together increased the annual milled rice production in step with increases in population. Diverse rice genotypes have enabled rice to endure crop constraints in fragmented landholdings spread over 43 m ha. AICRIP’s efforts have sustained availability of > 73 kg rice per capita per year (~ 40% of food grains). The process of notification, receipt of indent for BS from states, allotment and BS production, and de-notification of a cultivar by GOI need a review to ensure profits to farmers. As the 1000-seed weight varies in cultivars, it must be notified by GOI to adjust seed rate and maintain the recommended plant population at the farms. There is scope to increase the priceless BS production in cultivars to raise the country’s production further, facilitate export and ensure profits to all stakeholders.
