Power and influence mapping in Ghana's agricultural adaptation policy regime by Sova, Chase, Thornton, Thomas F., Zougmoré, Robert B., Helfgott, Ariella E.S., Chaudhury, Abrar S.

“…Results indicate that when taken collectively (the views of national, regional and local respondents combined) Ghana's adaptation regime is considered bipolar and elite-centred in its power distribution. A distinguishable ‘adaptation establishment’ or dominant group of power holders made up of technical government and international agencies can be identified. …”

Combined linkage and association mapping identifies a major QTL (qRtsc8-1), conferring tar spot complex resistance in maize by Mahuku, George S., Chen, J., Shrestha, R., Narro, L.A., Guerrero, K.V., Arcos, A.L., Xu, Y.

“…Identification of TSC resistant germplasm and elucidating the genetic mechanism of resistance is crucial for the use of host resistance to manage this disease. We evaluated 890 elite maize inbred lines in multiple environments and used genome wide association analysis (GWAS) with genotypic data from Illumina MaizeSNP50 BeadChip containing 56 K SNPs to dissect the genetics of TSC resistance. …”

High-density molecular characterisation and association mapping in Ethiopian durum wheat landraces reveals high diversity and potential for wheat breeding by Mengistu, D.K., Kidane, Yosef Gebrehawaryat, Catellani, M., Frascaroli, E., Fadda, Carlo, Pe, M.E., Dell'Acqua, Martin

“…Durum wheat (Triticum turgidum subsp. durum) improvement and adaptation to emerging environmental and climatic threats is hampered by the limited amount of allelic variation included in its elite breeding pool. It is therefore a priority to identify adaptive traits by exploring germplasm from different parts of the world, particularly centres of origin or diversity. …”

Genetic gains in yield and yield related traits under drought stress and favorable environments in a maize population improved using marker assisted recurrent selection by Bankole, F., Menkir, A., Olaoye, G., Crossa, J., Hearne, S., Unachukwu, N.N., Gedil, Melaku A

“…This approach was used to improve drought tolerance and grain yield (GY) in a biparental cross of two elite drought tolerant lines. The testcrosses of randomly selected 50 S1 lines from each of the three selection cycles (C0, C1, C2) of the MARS population, parental testcrosses and the cross between the two parents (F1) were evaluated under drought stress (DS) and well watered (WW) well as under rainfed conditions to determine genetic gains in GY and other agronomic traits. …”

Candidate gene sequencing and validation of SNP markers linked to carotenoid content in cassava (Manihot esculenta Crantz) by Udoh, L.I., Gedil, Melaku A, Parkes, Elizabeth Y., Kulakow, Peter A., Adesoye, A.I., Nwuba, C., Rabbi, Ismail Y.

“…We sequenced four candidate carotenoid genes from 167 cassava accessions representing the diversity of elite breeder lines from IITA. Total carotenoid content was determined using spectrophotometer and total β-carotene was quantified by highperformance liquid chromatography. …”
