Influence of Cowpea Mottle Virus and Cucumber Mosaic Virus on the Growth and Yield of Six Lines of Soybean (Glycine Max L.)

Abstract

Cowpea mottle virus is of localised importance on cowpea in Nigeria infecting several leguminous species and Cucumber mosaic virus is of worldwide distribution infecting several horticultural crops.A study was carried out in the screen house of the crop production pavilion,

Occurrence and distribution of pepper veinal mottle virus and cucumber mosaic virus in pepper in Ibadan, Nigeria

“…This corroborates the findings of Alegbejo [19] who reported that the proximity of pepper plants to certain important weed hosts also has contributed greatly to the spread of viral diseases of pepper. These weeds include Solanum nigrum, S. gracil, Physalis angulata, Vigna rosea, Vigna sinensis, Commelina nudiflora, Petunia hybrida, Physalis floridana, P. micrantha and Solanum incanum .…”

Growth and yield variability of groundnut (<i>Arachis hypogaea</i> L.) cultivars infected with cowpea aphid-borne mosaic virus disease

“…Infection due to CABMV has resulted in yield losses that ranged from 13 to 87 % and sometimes total crop loss could be encountered depending on the level of susceptibility of the cultivars (Alegbejo, 2015). Besides sole infection, CABMV can co-exist with other viruses like Cowpea mottle virus (CPMoV) or CMV (Arogundade et al, 2010), causing a mixed or combined infections with more damaging effect on farmers' field. Although a lot of studies have been conducted to determine the pathogenicity of CABMV disease on cowpea there is scanty information on the effect of the virus on groundnut in Nigeria.…”

Growth and yield components of some groundnut (<i>Arachis hypogaea</i> L.) cultivars infected with <i>blackeye cowpea mosaic virus</i>

“…Nearly 75 to 80 % of world's groundnut is grown by resource poor smallholder farmers in developing countries who routinely obtain yields of 500 -800 kg ha -1 as opposed to the potential yields of >2.5 t ha -1 (Idem and Showemimo, 2005). Low yields are mainly due to numerous diseases caused by fungi, viruses, bacteria and nematodes (Arogundade et al, 2010;Aliyu et al, 2011;Osei et al, 2013). Diseases in groundnut caused by Blackeye cowpea mosaic virus (BICMV), Cucumber mosaic virus (CMV), Groundnut bud necrosis virus (GBNV), Groundnut rosette virus (GRV), Indian peanut clump virus (IPCV), Peanut clump virus (PCV), Peanut mottle virus (PeMoV), Peanut stripe virus (PStV), Tobacco streak virus (TSV) and Tomato spotted wilt virus (TSWV) are the most economically important and are responsible for serious yield losses globally or regionally (Taiwo, 2001).…”

“…They are also known to naturally infect several other crops and inflict significant losses in them. Blackeye cowpea mosaic virus is a major virus disease of legume (Arogundade et al, 2010). It is flexuous, rod-shaped particles 750 mm long which induces characteristic pinwheel inclusions in infected cells.…”

“…Groundnut varieties infected with BICMV at the primary leaf stage showed 92-100 % infection at first trifoliate leaf. Disease symptoms include leaf discolouration, mosaic, mottling, vein banding, vein clearing, leaf deformation and yellow spot, while on seeds, shrivelling can be observed (Arogundade et al, 2010). There are severe green and yellow mosaic, vein banding, mottle, blistering, leaf roll and growth reduction on the whole plant.…”
