Farmers in sub-Saharan Africa do not have much choice of quality seed of vegetable cultivars adapted to local growing conditions and consumer demand. Only a handful of vegetable seed companies invest in local breeding research, while nearly all rely on seed imports. Our objective was to analyse to what extent existing seed laws and regulations enable or restrict the development of a research-based vegetable seed sector in Africa. Using a regulatory value chain approach, we analysed written laws and regulations for 13 countries and interviewed private and public sector stakeholders. We generally find that countries have taken a government-centred approach to seed quality control without recognizing that government agencies have little capacity to do this properly for vegetable crops. Mandatory Value for Cultivation and Use (VCU) trials and state-controlled seed certification are the two examples of regulatory approaches that may work for cereals but are not well suited for vegetables. No country has vegetable breeding as a goal in their national seed policy, and only four set out specific objectives for the vegetable seed sector. Tailoring seed policies, laws and regulations more specifically to vegetables could stimulate local variety development and seed production and benefit smallholder farmers and consumers at large.

Genebanks explore new partnerships with farmers and other user groups to provide smallholder farmers in Africa better access to crop diversity for improved nutrition, climate change adaptation and agricultural diversification. This paper shows how the World Vegetable Center (WorldVeg) genebank of traditional African vegetables and its partners distributed over 42,000 seed kits containing over 183,000 vegetable seed samples from 2013 to 2017 to smallholder farmers in Tanzania, Kenya and Uganda. The seed kits contained seed samples of promising accessions and open-pollinated breeding lines of traditional African vegetables, and to a lower degree of tomato, Capsicum pepper and soybean, usually enough to plant in a home garden. We identified four research questions to better understand the role of vegetable seed kits in strengthening local seed systems, impact on local vegetable diversity, improving human nutrition and supporting climate-resilient agriculture. As formal seed systems expand their reach, the genebank's role to supply vegetable diversity to public and private breeding programmes becomes more important. To optimize supply of vegetable diversity, the WorldVeg genebank of traditional African vegetables continues working with partners in both formal and local seed systems. [ABSTRACT FROM AUTHOR]
