Incorporating male sterility increases hybrid maize yield in low input African farming systems.

Maize is a staple crop in sub-Saharan Africa, but yields remain sub-optimal. Improved breeding and seed systems are vital to increase productivity. We describe a hybrid seed production technology that will benefit seed companies and farmers. This technology improves efficiency and integrity of seed production by removing the need for detasseling. The resulting hybrids segregate 1:1 for pollen production, conserving resources for grain production and conferring a 200 kg ha-1 benefit across a range of yield levels. This represents a 10% increase for farmers operating at national average yield levels in sub-Saharan Africa. The yield benefit provided by fifty-percent non-pollen producing hybrids is the first example of a single gene technology in maize conferring a yield increase of this magnitude under low-input smallholder farmer conditions and across an array of hybrid backgrounds. Benefits to seed companies will provide incentives to improve smallholder farmer access to higher quality seed. Demonstrated farmer preference for these hybrids will help drive their adoption.

Unpacking the 'Business Model' for Fortification Initiatives in Low- and Middle-Income Countries: Stakeholder Identified Drivers of Success and Constraints to Progress.

Background: Initiatives to tackle micronutrient deficiencies (MNDs) in low-and middle-income countries (LMICs) have increased steadily in recent years. Commodities such as staple foods (e.g., cereals) and condiments (e.g., salt) have been targeted as 'vehicles' for industrial fortification through numerous projects and initiatives. However, mixed experiences with delivery, coverage and sustainability have been found. Methods: Using an online survey of 71 key stakeholders (from 35 countries) consisting of the public/private sector, academia and civil society, this study sought to unpack the 'business model' for fortification initiatives to identify the key drivers of success and constraints faced by stakeholders in LMICs. Bivariate analysis was conducted to identify factors associated with the coverage of the target market and the perceived success and sustainability of fortification initiatives. Results: We identified four key factors contributing to the success of fortification initiatives. The first involves the size of the firm. Large firms had a significantly higher (p < 0.05) self-sustaining index (perceived level of sustainability of the fortification initiative) than smaller sized firms. In addition, a higher perceived success score (p < 0.05) was associated with non-targeted initiatives compared to those specifically targeted at a certain cohort of the population, further illustrating the benefits of producing at scale. Secondly, a significant relationship was found between whether standards were enacted and the coverage of the target market by the project/firm (p < 0.05).). The third key factor relates to the ability to source adequate testing for the fortified produce in-house. A positive correlation was found for post-mix in-factory testing and the self-sustaining index (p < 0.05). Finally, delays to importation and high charges were cited as key constraints to the use of premix. Conclusions: We argue therefore that a successful 'business model' for industrial fortification initiatives invariably consist of: (i) the involvement of larger sized firms that have the advantage of benefiting from economies of scale; (ii) the availability and application of agreed standards by the producer; (iii) high quality assurance/compliance monitoring (including post-mix testing where relevant), and; (iv) the ability to procure premix in a timely/cost-effective manner. These criteria are likely to be important factors that contribute to the success of fortification initiatives in LMICs.

Consumer Acceptance and Willingness to Pay for Instant Cereal Products With Food-to-Food Fortification in Eldoret, Kenya.

BACKGROUND: Maize is the major food staple in East and Southern Africa, where food-processing industries are emerging fast. New low-cost extrusion cookers allow small enterprises to enter the market for processed cereals, including instant, fortified, and flavored products. OBJECTIVE: Assess consumers' interest and preferences for the new products. METHODS: Consumers (n = 220) in Eldoret, Kenya, were invited to evaluate 4 new cereal products: (1) sifted maize flour mixed with sorghum, (2) instant sifted mixed flour, (3) instant whole flour, and (4) instant whole flour fortified with natural ingredients and to compare them to conventional sifted maize flour, using 2 preparations: stiff porridge (ugali) and soft porridge (uji). These were followed by economic experiments to estimate consumers' willingness to pay (WTP) for the new products and traits. RESULTS: For ugali, consumers preferred conventional sifted maize flour, while for uji, they appreciated the new products, especially sifted mixed flour (with sorghum) and instant whole mixed flour. Fortification with food-to-food sources was not appreciated, especially for ugali. Comparing WTP for the traits with their production cost showed that mixed, whole, and instant flours were economical, but not fortification. Maize/sorghum mixtures realized a benefit of 24% over conventional maize flour, whole meal 11%, and instant mixtures 5%. CONCLUSIONS: There is a potential market for improved cereal products in Kenya, but more for uji than for ugali, especially with instant, mixed, and whole flour. Acceptable and affordable products, fortified with other foods that are locally available, however, still need to be developed, especially for ugali.
