The current status of cassava Begomoviruses, the most serious constraint to the production of cassava, a major staple food crop in sub-Saharan Africa, is reviewed in relation to their distribution, effects, etiology, and epidemiology. It is concluded that control of the diseases would continue to...

(ACMV) were assessed in shoots regenerated from single-node cuttings of three cassava genotypes differing in resistance to ACMV. Plants of the moderately resistant TMS 4(2)1425 and susceptible TMS 60506 did not recover from the disease as rapidly as those of the resistant TMS 30001, Recovery was ...

The effect of mixed infection of cowpea aphid-borne mosaic (CAMV) and cucumber mosaic (CMV) viruses on cowpea yield varied with the resistance levels of cowpea lines, since there was a strong interaction between the latter and virus infection types atP ≤ 0.01. In cowpea line TVu 3629, with low re...
