tailieunhanh - Host range of aphid transmissible mosaic virus infecting cowpea

Cowpea (Vigna Unguiculata L. Walp.) is one of the World’s important leguminous food crop and is commonly affected by viral disease transmitted by aphid vector in nonpersistent manner. Present study was attempted on aphid transmissible virus infecting cowpea, during 2015-16. Symptoms on experimental field and mechanical transmission were characterized by mosaic, veinal necrosis, vein clearing, vein banding, blistering, stunting, leaf deformations, chlorosis and cupping of leaves. Further, Aphid transmissible virus of cowpea has restricted host range and infected only four plant species viz., Chenopodium amaranticolor, Glycine max (L.) Merr, Vigna unguiculata Var. Gomati, and Nicotiana benthamiana L. The virus failed to infect 20 plant species. | Host range of aphid transmissible mosaic virus infecting cowpea
