A.  aEffect of cassava mosaic virus on yield of cassava.h[electronic resource]  c1982  aYield reductions of cassava infected with cassava mosaic virus under field conditions ranged from 24 to 75%. Therer was a strong correlation between disease severity and yield loss. Incorporation of yield loss assessments in evaluation of varieties for mosaic resistance would seem advisable in view of these results.  aDoença  aMandioca  aDiseases  aMelhoramento genetico  aPlant breedeing  tPlant Diseasegv.66, n.8, p.661-662, 1982.
