| dc.description.abstract | Twelve cassava landraces were evaluated for sources of resistance genes to diseases and pests of major economic
importance in Africa. The objective was to assess their levels of field resistance to mosaic disease (ACMD), bacterial
blight (CBB), anthracnose (CAD), and green mite (CGM), compared to TMS30572, an elite cultivar widely adopted in
Africa. Considerable genotypic variation was observed among cultivars for resistance to ACMD and CGM but not for
CBB and CAD. The lowest mean incidence of 12% and severity of 1.8 on a scale of 1–5 for ACMD was recorded for
Atu, a landrace with farmer acceptable qualities. In comparison, the improved cultivar, TMS 30572, had a mean disease
incidence of 72% and a severity score of 2.8. Another landrace, MS-20 had the lowest CGM damage score (2.1) while
TMS 30572 emerged as one of the susceptible cultivars with a damage score of 3. Additional sources of resistance to
ACMD and CGM that may possibly be better than the popular improved cultivar, TMS 30572, were identified in this study.
These could serve as novel sources of additional genes to complement existing resources for elite cassava breeding in
Africa. |
