Izy io dia manasongadina ny toetra manokana an'ny karazana tsirairay, ary koa ny tombony ara-pambolena sy ara-tsakafo.Item Karazana vomanga sy ny toetra mampiavaka azy(Brief, 2025-04) Ralisoa, N.; Rasoloniaina, B.Item Anjara birikin’ny vomanga miaty laoranjy amin’ny ady amin’ny tsy fanjarian-tsakafo sy ny fanoitra amin’ny fiovan’ny toetrandro any amin’ny faritra karankaina eto Madagasikara(Brief, 2025-04) International Potato CenterItem Systeme semencier de la pomme de terre a Madagascar(Brief, 2025) Wauters, P.; Rasoloniaina, B.; Rukundo, P.; Sharma, K.; Atieno, E.; Nyawade, S.; Ralisoa, N.; Raoelimanana, H.Item Maximizing genetic gains while maintaining an efficient sweetpotato breeding cycle in SSA: Lessons from NARO-NaCRRI(Brief, 2025-03-25) Serenje, G.; Njobvu, J.; Makunde, G.S.; Musundire, L.; Sneller, C.The optimization of sweetpotato breeding pipelines in Sub-Saharan Africa (SSA) is crucial for improving genetic gains while ensuring efficiency in resource allocation. Using the deterministic model, the outcomes to modifications to the national sweetpotato breeding program at NaCRRI-NARO were simulated. Heritability assessments revealed that genotype-by -environment interactions account for just 16% of total phenotypic variation, with moderate heritability observed in stage-1 (0.26) and stage-2 (0.56) trials. The simulations revealed that selection efficiency will be greatly improved by making changes breeding pipeline including 1) reducing plot sizes and replicates in stage-3 trials, 2)reallocating resources from National Performance Trials (NPT) to earlier-stage trials, 3) conducting stage-2 and stage-3 trials in a single season instead of two and 4 expanding the total number of clones tested per year from 3,561 to 6,682 (+87.6%). This translates to doubling the number of clones at stage-1 from 3,000 to 6,000 (+100%) and increasing the number of clones at stage-2 clones from 500 to 650 (+30%). This larger breeding population enhances the probability of identifying superior lines across multiple trait targets. However, early-stage phenotypic selection, due to lower heritability, limits overall genetic gains. To counteract this, genomic selection (GS) is proposed as a complementary strategy, improving early-stage selection accuracy and efficiency. Growing the stage-2 and 3 trials for just one season has the potential to increase the genetic gain per year (Gy) by 9%. By integrating optimized resource allocation, expanded selection populations, and genomic selection approaches, NaCRRI-NARO’s sweetpotato breeding program demonstrates a model for maximizing genetic gains while maintaining an efficient and scalable breeding framework in SSA.Item Maximizing genetic gains while maintaining an efficient sweetpotato breeding cycle in SSA: Lessons from ZARI-Zambia(Brief, 2025-03-25) Serenje, G.; Njobvu, J.; Makunde, G.S.; Musundire, L.; Sneller, C.Item GROWING Nutritious Foods, GROWING Futures. Starting to work with two times more Growing Future Clubs while designing and implementing the innovative market linkage component.(Brief, 2024-10) Temesgen, B.B.; Gyan-Bassaw, P.Management complexity of the project increased as this period focused on the setting up of the innovative market linkage component and farming as a business training to serve 37 Cycle 1 Growing Futures Clubs (GFCs), while year 1 trainings and dissemination of the planting materials in the gender-transformative, climate-smart agriculture-nutrition-savings components of the two-year intervention for the 72 Cycle 2 GFCs took off. The 2024 agricultural season experienced more than 40 days of drought during July-August, affecting demonstration plots and reducing yields, but also highlighting the greater resilience of orange-fleshed sweetpotato (OFSP) compared to maize. Monitoring efforts indicate that the gender-transformative approach is positively influencing dietary behaviors and gender relations within many households.Item CGIAR’s Flagship Report: Rooted Apical Cuttings -Q & A.(Brief, 2025) International Potato CenterCGIAR’s first Flagship Report will be launched in April 2025. The report is being driven by decision-makers especially at the national level who have requested we present a portfolio of options where science has been shown to help them make informed decisions and navigate trade-offs – and have particularly requested examples that have decision-making tools that translate the science – in other words, not the science papers or technical reports.Item Potato seed systems in Madagascar(Brief, 2025-02) Wauters, P.; Rasoloniaina, B.; Rukundo, P.Item A Machine Learning Approach for Estimating sweetpotato Cultivation Areas in Uganda(Brief, 2024-12) Rajendran, S.Item Enhancing the Seed Sector Decision-Making with the Business Investment Decision (BID) Tool – a brief on BID tool(Brief, 2024-12) International Potato CenterItem Cultivating Change: Leveraging Gender Analysis for Improving Farmers’ Potato Health Management in the Andes(Brief, 2024-12) Pérez, W.; Fonseca, C.; Kawarazuka, Nozomi; Andrade-Piedra, J.L.; Kreuze, Jan F.Item Cultivando el Cambio: Integrando el Enfoque de Género para Fortalecer la Gestión de la Sanidad Vegetal en el Cultivo de Papa de los Agricultores Andinos(Brief, 2024-12) Pérez, W.; Fonseca, C.; Kawarazuka, Nozomi; Andrade-Piedra, J.L.; Kreuze, Jan F.Item Building regional capacity to manage invasive pests and diseases to safeguard sustainable seed potato trade(Brief, 2024-12) Sharma, K.; Atieno, E.Item Rooted in Resilience: Sweetpotato Cultivation and Consumption Amid Conflict – Lessons from Tigray, Ethiopia(Brief, 2024-12) Tesfay, H.; Gebeyeu, S.; Hadush, M.; Cherinet, M.; Asfaw, F.; Abraha, Z.; Mesele, T.Item Caracterizar la agrobiodiversidad es clave para adaptar los sistemas agrícolas andinos a la sequía y las plagas(Brief, 2024) Navarrete, I.; Borja, R.; Oyarzún, P.; Amagua, J.; Sánchez, V.; Cuesta, X.; Ochoa, J.; Ccanto, R.; Ruiz, V.; Heider, B.
