Business models for early generation seed production and marketing

Sustainable access to early generation seed (EGS) is important for efficient supply of quality certified, standard and/or quality declared seed of improved high-performing crop varieties. Some studies have been conducted from a global perspective on the delivery of EGS with a major focus on the economic analysis and identification of effective pathways for sustainable supply. This study was designed to establish the best practices and critical factors for the delivery of EGS for grain legume and dryland cereal crops in selected countries in sub-Saharan Africa (SSA) and parts of South Asia. A literature review of specific business models applied in SSA and India was conducted. More information was gathered through in-depth interviews with specific key informants drawn from the respective institutions or agencies that were studied. The models include public-sector or research-led models, private -sector models, and public-private partnership models. This working paper presents a synthesis of best practices and approaches through which the specific business models ensure the production and supply of breeder and foundation seeds. The paper identifies practices involving mechanisms for planning, financing, infrastructural facilities required for EGS production, incentives to promote pure line crop EGS production by the private sector, and the methods of production. The study reveals critical constraints for EGS production and supply, including seed market vagaries; the short shelf life of some crop seeds like groundnut; limited maintenance breeding efforts; low quality of breeder seed; lack of infrastructure to produce EGS; breeder seed production does not match the demand for production of foundation seed while foundation seed production does not match the demand for production of certified seed; and high costs of supervising and managing various groups of seed outgrowers. Interventions that build the capacity of seed producers to effectively plan EGS production requirements, guided by a seed roadmap, and product cycle management are needed. The public research institutions need to be strengthened with facilities that enhance their capacity to produce sufficient quantities of breeder seed at the required time. Besides, the proceeds from the sales should “revolve” to enable the unit to make further investments and carry out all the necessary operations in a timely manner. This requires consultation with Governments to set up financial management structures that provide an easier accountability process. Incentive schemes should be developed to encourage investment in the production of pure-line grain legumes and dryland cereals by the private sector as well as enhance their role in popularizing new varieties. Improvement and enforcement of quality assurance and control systems by breeding programmes, including modern technological methods should be considered. Importantly, a handover system that includes lisencing and pre-orders would help to bridge the supply and demand disparity

Scoping the implementation of recommendations from previous early generation seed studies in sub-Saharan Africa

The purpose of this report is to document and track progress on the implementation of recommendations from EGS studies that were carried out on selected countries in Eastern and Southern Africa (ESA) and West and Central Africa (WCA). The recommendations were designed to ensure a sustainable supply of EGS based on market-specific archetypes involving private, public and public-private partnerships. For the subsequent years following the conclusion and adoption of the study reports, there have been some significant achievements registered based on the country-specific recommendations from the studies. This report provides a review of the extent of implementation of the recommendations in each of the mentioned countries. The study involved a review of literature which included the country-specific EGS studies and the available literature that comprised of projects reports, recent policy documents and any other relevant available literature. Despite the list of countries in which the studies were conducted, this study only focused on the implementation of recommendations in Uganda, Kenya, Tanzania, Rwanda, Malawi, Ghana and Nigeria. Most countries have to a large extent implemented most of the recommendations from the EGS studies. A lot of emphasis was placed on addressing the creation of enabling environment aspects such as the enactment of seed acts, the plant variety protection bill and policies in Nigeria, Uganda, Ghana as well as harmonization between the national and regional seed laws. There was also emphasis towards capacity building for seed regulation and certification services through training of human resources and enabling private sector participation in seed inspection in addition to accreditation by the international bodies ISTA and OECD. PPPs were established for the root and tuber crops cassava and potatoes; and mainly hybrid and OPV maize for the cereal crops. Fingerprinting of parental lines is the most notably unimplemented for all the countries that it was recommended, but also the national establishements such as Variety Testing Center, demand forecasting frameworks and National Seed Steering committee for the case of Malawi and Tanzania respectively. It is therefore recommended that further investigation of gaps in implementation be carried to understand reasons for non-implementation

Designing self-sustaining early generation seed supply systems: The must-dos

Shortages in the supply of quality early generation seed (EGS) of new and improved varieties, particularly of dryland cereals and legumes is a major challenge because of the business models.This triggers the following questions: what EGS business models would sustainably avail quality parent seed? To investigate this, we documented 16 EGS interventions. We found that pre-securing seed market ahead of production played important role in the successful seed business. Taking different forms (e.g., pre-orders, demand forecasting, pre-aggregation of demand, joint planning,contractual agreement), it brings confidence to EGS producers to continuously invest in the business and make it profitable. For sustainable EGS production and supply in sub-Saharan Africa, we advocate for market assurance in advance. Two guiding principles are also suggested and four recommendations formulated

Redesigning crop varieties to win the race between climate change and food security

Climate change poses daunting challenges to agricultural production and food security. Rising temperatures, shifting weather patterns, and more frequent extreme events have already demonstrated their effects on local, regional, and global agricultural systems. Crop varieties that withstand climate-related stresses and are suitable for cultivation in innovative cropping systems will be crucial to maximize risk avoidance, productivity, and profitability under climate-changed environments. We surveyed 588 expert stakeholders to predict current and novel traits that may be essential for future pearl millet, sorghum, maize, groundnut, cowpea, and common bean varieties, particularly in sub-Saharan Africa. We then review the current progress and prospects for breeding three prioritized future-essential traits for each of these crops. Experts predict that most current breeding priorities will remain important, but that rates of genetic gain must increase to keep pace with climate challenges and consumer demands. Importantly, the predicted future-essential traits include innovative breeding targets that must also be prioritized; for example, (1) optimized rhizosphere microbiome, with benefits for P, N, and water use efficiency, (2) optimized performance across or in specific cropping systems, (3) lower nighttime respiration, (4) improved stover quality, and (5) increased early vigor. We further discuss cutting-edge tools and approaches to discover, validate, and incorporate novel genetic diversity from exotic germplasm into breeding populations with unprecedented precision, accuracy, and speed. We conclude that the greatest challenge to developing crop varieties to win the race between climate change and food security might be our innovativeness in defining and boldness to breed for the traits of tomorrow

Optimum Plant Density for Increased Groundnut Pod Yield and Economic Benefits in the Semi-Arid Tropics of West Africa

Groundnut is a very important crop in the West and Central Africa (WCA) region, accounting for almost 70% of Africa’s groundnut production in 2019. Despite its economic importance, the crop’s yield is still low. For a high yield and profitable economic returns, optimal plant density is a fundamental crop management practice. Plant density experiments were conducted at the ICRISAT-Mali research station between 2016 and 2021 over the main rainy and dry seasons to determine the optimum density for maximum groundnut yield and economic benefits. The treatments contained row spacing of 20 cm, 30 cm, 40 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, and 100 cm, with intra-row spacing of 10 cm, 15 cm, and 20 cm. Results showed that when plant density was increased, dry pod yield, production value, and net economic benefit per hectare increased in a no moisture stress scenario. During the rainy season, the 40 cm × 10 cm spacing gave the highest dry pod yield (1693 kg), production value ($891.6), and net benefit ($403.5) per hectare. The highest dry pod yield (3703 kg), production value ($2173), and net benefit ($1510.2) per hectare were obtained from 30 cm × 10 cm spacing during the dry season. The number of pods per plant and 100 SW increased with lower plant densities. Therefore, it is recommended to increase plant density to at least 222,000 plants per hectare in the Sudan Savannah agroecology of WCA

DNA markers reveal genetic structure and localized diversity of Ethiopian sorghum landraces

North Eastern Ethiopia is a major sorghum-growing region. A total of 415 sorghum landraces were sampled to represent the range of agro-ecologies (three altitude ranges) as well as spatial heterogeneity, that is, 4 zones: North Welo, South Welo, Oromiya and North Shewa with each zone containing 2 to 5 districts. The landraces were genotyped with simple sequence repeats (SSR) and inter simple sequence repeats (ISSR) markers. High genetic diversity was observed among the landraces for both marker systems. STRUCTURE analysis revealed 4 clusters of genetically differentiated groups of landraces. Cluster analysis revealed a close relationship between landraces along geographic proximity with genetic distance between landraces increasing with an increase in geographic distance. The grouping of landraces based on districts was influenced by clinal trend and geographic proximity. The FST statistics showed significant geographic differentiation among landraces at various levels of predefined geographic origin but a large portion of the variation was among landraces within rather than between predefined populations. The landraces from North Shewa were predominantly in one cluster, and landraces from this area also exhibited the greatest allelic diversity and the highest number of private alleles. There was low variation among the highland Zengada landraces, but these landraces were quite strongly differentiated and fell into one population cluster. The low to moderate genetic differentiation between landraces from various geographic origins could be attributed to gene flow across the region as a consequence of seed exchange among farmers.Keywords: Differentiation, diversity, landraces, simple sequence repeats (SSR), sorghu

Variability and Correlations among Groundnut Populations for Early Leaf Spot, Pod Yield, and Agronomic Traits

The present experiment was conducted in Mali to study the genetic variability and correlation of early leaf spot (ELS) resistance parameters and agro-morphological traits in groundnut using two F3 populations from crosses QH243C X NAMA and TS32-1 X NAMA. Estimates of genotypic coefficient of variation and phenotypic coefficient of variation revealed high value for pod yield, kernel yield, and ELS score at 60 and 80 days after sowing for the cross QH243C X NAMA. Low-to-moderate GCV and PCV were obtained for the remaining traits for both crosses. High heritability values coupled with high genetic advance as percentage of mean recorded for ELS_II, defoliation percent, pod yield in cross QH243C X NAMA; shelling percent for the cross TS32-1 X NAMA and ELS_III; and plant height, kernel yield in both crosses, indicate the significant role of additive gene action for inheritance of these traits. Correlation analysis indicated that pod and kernel yield were significant and positively correlated with 100 kernel weight and shelling percent. For cross QH243C X NAMA, kernel yield showed significant positive correlation with all ELS resistance components but the correlation was not significant for the cross TS32-1 X NAMA. Positive and significant correlation was observed between ELS resistance components themselves, suggesting that these components could be controlled by a similar polygenic system. The findings suggest that early generation selection should be effective for days to first flowering, days to 50% flowering, plant height, pod yield, kernel yield, 100 kernel weight and early leaf spot resistance which recorded the highest value of heritability in the two crosses
