Access and benefit-sharing policies for climate-resilient seed systems. por Halewood, Michael, Otieno, G., Nkhoma, C., Kasasa, P., Mulumba, John W., Gapusi, J., Jonge, B. de

“…This study provides an overview of climate related changes in past, present and future and the challenges to access to and exchange of genetic resources for climate change adaptation through different access and benefit sharing regimes in 4 countries – Zambia, Zimbabwe, Rwanda and Uganda. Findings from the studies indicate that most African countries face challenges in accessing required PGR for climate change adaptation because they do not have online accession-level documentation; they have not fully implemented international commitments related to ABS and national and regional seed laws hamper the flow of seeds and genetic resources. …”

Impediments to new improved maize variety testing and release in selected countries in sub-Saharan Africa por Setimela, P.S., Badu-Apraku, Baffour, Mwangi, W.

“…A survey was conducted on the varietaltesting and release systems in 14 selected countries (Angola, Benin, Ethiopia, Malawi, Ghana, Mali, Mozambique, Nigeria, Tanzania, Kenya, South Africa, Uganda, Zambia, and Zimbabwe) in SSA. The results from the study show that regulations on variety testing and release procedures in the various countries are overlapping and rigid hindering the deployment and commercialization of new improved maize germplasm. …”

Toward greater sustainability: How investing in soil health may enhance maize productivity in Southern Africa por Thierfelder, Christian L., Paterson, E., Mwafulirwa, L., Daniell, T., Cairns, Jill E., Mhlanga, Blessing, Baggs, Elizabeth M.

“…Here we examined the effects of NT as compared with conventional tillage without residue retention on relationships between soil characteristics and maize (Zea mays L.) productivity in long-term on-farm and on-station trials in Zimbabwe. Our results show that relationships between soil characteristics and maize productivity, and the effects of management on these relationships, varied with soil type. …”

Combining ability and testcross performance of multi-nutrient maize under stress and non-stress environments por Goredema-Matongera, Nakai, Thokozile Ndhlela, Biljon, Angeline van, Casper Nyaradzai Kamutando, Labuschagne, Maryke T.

“…In this study, 11 newly introduced Zn-enhanced inbred lines were inter-mated with seven testers from normal, provitamin A and quality protein maize (QPM) nutritional backgrounds in order to estimate the general combining ability (GCA) and specific combining ability (SCA) for grain yield (GY) and secondary traits under stress conditions [(combined heat and drought stress (HMDS) and managed low nitrogen (LN)] and non-stress conditions [(summer rainfed; OPT) and well-watered (irrigated winter; WW)] in Zimbabwe. Lines L6 and L7 had positive GCA effects for GY and secondary traits under OPT and LN conditions, and L8 and L9 were good general combiners for GY under HMDS conditions. …”
