Description
Summary:The improved cassava mosaic-resistant cassava variety TMS 30395 produced significantly higher root yields under field conditions than its susceptible parent Isunikakiyan, irrespective of whether it was established from mosaic-free or mosaic-infected planting material. Significant reductions in fresh root yield, root number, root size, top fresh weight and starch content in both varieties resulted from plants established from CMD-infected planting material. For the variety Isunikakiyan, yield reduction was greater in plants established from clonal CMD-infected cuttings than in those established from disease-free cuttings but which later became infected through vector transmission.
