    • Varietal diversity as a lever for cassava variety development: exploring varietal complementarities in Cameroon 

      Takam-Tchuente, H.N.; Fongang Fouepe, G.H.; Mbwentchou Yao, D.C.; Mathe, S.; Teeken, B. (2023)
      BACKGROUND: Cassava is an important crop for the survival of smallholder farmers in Cameroon. However, the cassava sector has a low production per unit area compared to the technological potential in this country. In this context, breeders have developed varieties based mainly on their potential in terms of yield and disease resistance. These varieties have been widely disseminated in Cameroon within the framework of development projects. However, these releases have not achieved the expected ...
    • Seasonal abundance of Paracoccus marginatus (Williams and Granara de Willink) (Hemiptera: Pseudococcidae) and damage to papaya seedlings in three agroecological zones in Southwestern Nigeria 

      Larayetan, A.A.; Adedire, C.O.; Umeh, V.; Goergen, G. (2021)
      The Papaya Mealybug, Paracoccus marginatus Williams and Granara de Willink, is an invasive species. The abundance of the papaya mealy bug and its damage to seedlings were investigated in the field at three agro-ecological zones: which includes Akure (Rainforest), Ogbomoso (Guinea savannah), Ibadan (Derived savannah) in the 2016 growing seasons. At each site, 10 healthy mother plants with fruit (> 17cm GBH) were randomly selected from which five infested and non-infested leaves (fifth to the 13th ...
    • Identification of diagnostic KASP-SNP markers for routine breeding activities in yam (Dioscorea spp.) 

      Agre, A.P.; Clark, L.V.; Garcia-Oliveira, A.L.; Bohar, R.; Adebola, P.O.; Asiedu, R.; Terauchi, R.; Asfaw, A. (2023)
      Maintaining genetic purity and true-to-type clone identification are important action steps in breeding programs. This study aimed to develop a universal set of kompetitive allele-specific polymerase chain reaction (KASP)-based single nucleotide polymorphism (SNP) markers for routine breeding activities. Ultra-low-density SNP markers were created using an initial set of 173,675 SNPs that were obtained from whole-genome resequencing of 333 diverse white Guinea yam (Dioscorea rotundata Poir) genotypes. ...
    • Hydroxamic acids: New players in the multifactorial mechanisms of maize resistance to Striga hermonthica 

      Marcotrigiano, R.A.; Carluccio, A.V.; Unachukwu, N.; Adeoti, S.R.; Abdulsalam, T.; Gedil, M.; Menkir, A.; Gisel, A.; Stavolone, L. (2023-11)
      Striga hermonthica is the most widespread and destructive plant parasite infesting maize and other major crops in sub-Saharan Africa where it causes severe yield losses and threatens food security. Several tolerant maize lines supporting reduced S. hermonthica emergence have been deployed. However, the molecular bases of such resistance are yet poorly understood. Based on a time course comparative gene expression analysis between susceptible and resistant maize lines we have confirmed resistance ...

    • Prioritizing preferred traits in the yam value chain in Nigeria: a gender situation analysis 

      Okoye, B.; Ofoeze, M.; Ejechi, M.; Onwuka, S.; Nwafor, S.; Onyemauwa, N.; Ukeje, B.; Eluagu, C.; Obidiegwu, J.; Olaosebikan, O.; Madu, T. (2023-11-13)
      This study describes what did and did not work in the prioritization of preferred traits within the value chain of yam and associated food products (boiled and pounded yam) in Nigeria. Demand-led breeding protocols have enhanced participatory methods along gender lines to increase the clarity of information on the yam traits preferred by farmers and other end users. Drawing on the experience of the cross-cutting gender team at the National Root Crops Research Institute (NRCRI), Umudike, and partners, ...

    • Evaluation of genotypic variability and analysis of yield and its components in irrigated rice to stabilize yields in the Senegal river valley affected by climate change 

      Moukoumbi, Y.D.; Bayendi Loudit, S.M.; Sikirou, M.; Mboj, D.; Hussain, T.; Bocco, R.; Manneh, B. (2023)
      Rice is an important cereal crop in many countries, but its production in the Senegal River Valley is hampered by adverse climatic conditions. This study was aimed at evaluating the diversity among genotypes and the association between several phenological and yield attributes of irrigated rice to mitigate the consequences of climate change. During the dry season of 2013–2014, 300 irrigated high yielding oryza sativa indica panel were used in an Alpha-lattice experiment at the Ndiaye research ...

    • Small scale farm mechanization catalogue: Clearinghouse technical report series 015 

      TAAT (Technologies for African Agricultural Transformation, 2022-07)
      Small-scale mechanization is the key to reducing drudgery and increasing productivity among African farmers. For too long farming in Africa is regarded as a path to poverty rather than a profitable agribusiness. This is due in large part for dependency upon tedious hand labor, poor returns to effort and lack of investment into farming systems. A wide range of small-scale equipment is available to improve returns to labor and change this poor image of farming. This equipment include tillers, power ...

    • Entrepreneurial and attitudinal determinants for adoption of Climate-smart Agriculture technologies in Uganda 

      Kirungi, D.; Senyange, B.; Wesana, J.; Sseguya, H.; Gellynck, X.; De Steur, H. (2023)
      Climate-Smart Agriculture (CSA) technologies have great potential to minimize climate risks, sequester carbon, improve food security, and achievement of Sustainable Intensification (SI) goals. This makes their adoption a necessity for achieving sustainable agricultural systems. Despite the benefits and all efforts, smallholder farmers in developing countries still have low adoption of CSA technologies. This study explored the determinants of intentions to start and continue adopting CSA technologies. ...
    • Targeted knockout of early nodulin-like 3 (MusaENODL3) gene in banana reveals its function in resistance to Xanthomonas wilt disease 

      Ntui, V.O.; Tripathi, J.; Shah, T.; Tripathi, L. (2023-11-28)
      Nodulins and nodulin-like proteins play an essential role in the symbiotic associations between legumes and Rhizobium bacteria. Their role extends beyond the leguminous species, as numerous nodulin-like proteins, including early nodulin-like proteins (ENODL), have been identified in various non-leguminous plants, implying their involvement in functions beyond nodulation, such as nutrient transport and growth modulation. Some ENODL proteins have been associated with plant defense against pathogens, ...
