Simple sequence repeat (SSR) diversity of cassava in South, East and Central Africa in relation to resistance to cassava brown streak disease por Pariyo, A., Tukamuhabwe, Phineas, Baguma, Yona K., Kawuki, Robert S., Alicai, Titus, Gibson, P.J., Kanju, E., Wanjala, Bramwel W., Harvey, Jagger J.W., Nzuki, I., Rabbi, Ismail Y., Ferguson, Morag E.

“…The major findings from this study were: (1) little genetic differentiation was confirmed among countries (7%) with the majority of variation distributed among individuals (93%), (2) the frequency of alleles putatively associated with resistance to CBSD was found to be generally low (0.2 to 0.5) but widely dispersed in the cassava germplasm of the SEC Africa region implying that if validated the markers will be useful for marker-assisted breeding on a broad scale, (3) several distinct putative sources of resistance to CBSD seem to be present in the cassava germplasm of SEC Africa offering the potential to pyramid genes for more effective and durable resistance and (4) it may be more informative to assess cassava diversity in the SEC Africa region based on pedigree (if known) or genetic relatedness, rather than geographical origin.…”

The effect of communication media on the uptake of agricultural innovations in selected states of Nigeria por Atser, G., Dixon, A., Ekeleme, F., Hauser, S., Fadairo, O., Adekoya, A., Ayanwale, A.B., Agada, M., Oladokun, I., Akpu, P., Sanni, L., Pypers, P., Ampadu-Boakye, T., Vanlauwe, Bernard

“…Theoretical implications Findings on the influence of communication media on improved weed control and agronomy are significant, given that there is little well-documented data on how communication media enhances technology and innovation adoption in arable crop farming. Originality/value This study generates important data that reinforces the imperatives of communication and media choices, and further underpins the debate that technology alone cannot lead to uptake by farmers but needs to be communicated.…”
