“…These differences were similar to those obtained by Bashir et al (2002) with CABMV or several other viruses transmitted by seeds (Johansen et al, 1994). These results show that seeds represent an effective way to maintain the virus and these seeds constitute a source of primary inoculum of CABMV.…”

02/08 Fax : (226) 25 31 92 75 A B S T R A C T Cowpea (Vigna unguiculata (L.) Walp.) is one the main leguminous crop plants world wide, particularly in sub-Saharan Africa where the rainfall is low and often unevenly distributed. However, its production is limited by insect attacks and numerous diseases including those caused by viruses. In Burkina Faso, the Cowpea Aphid-Borne Mosaic Virus (CABMV) is one of the viruses capable of causing 7-60% of yield losses. The aim of this study is to assess the susceptibility of 21 cowpea varieties against CABMV and to also assess the yield losses caused by this virus on each of the varieties. In this context trial was conducted on INERA research stations at Kamboinsé and Farako-Bâ in 2012 and 2013. Twenty one varieties were used for this study. The experimental design used is a split-plot with 4 repetitions for which the first 2 repetitions were inoculated with the CABMV. Symptoms caused by the CABMV on the 21 varieties of cowpea were of a great diversity. The assessment of the virus in infected plant samples from these varieties by ELISA test allowed detecting the mosaic virus in all samples that presented mosaic symptoms. The number of flowers and pods strongly varied depending to the type of plant (inoculated or non-inoculated plant) and the variety. Yields from the different varieties, comprised between 187 and 6250 kg haG 1 , were influenced by the site, the year, the variety and the type of plant. Yields losses were ranged from 3-64% depending to the variety.

“…The CABMV J. Plant Pathol., 9 (2): 83-90, 2015 belonging to genus Potyvirus, has been accounted as the most widespread and important constraint on cowpea crop in all of cowpea grown agro-ecological zones (Emechebe and Lagoke, 2000;Bashir et al, 2002). Consequently, the present investigation aimed at identifying putative resistance sources against CABM virus, the most prevalent virus at Trombay.…”

“…The CABMV has been reported in many countries in different continents including Asia, Africa, Europe, North and South America and Australia (Mali and Kulthe, 1980;Huguenot et al, 1993;Bashir and Hampton, 1996;Pio-Ribeiro et al, 2000;Behncken and Maleevsky, 1977). Since, biological properties of CABMV may differ among isolates worldwide (Bashir et al, 2002); it becomes imperative to identify resistance sources against the local prevalent viral strains. Therefore, screening of genotypes using sap inoculation of the prevalent CABMV strain was carried out and has resulted in the identification of 13 highly resistant genotypes against this virus (Table 3).…”

Cowpea (Vigna unguiculata (L.) Walp), an important protein rich arid legume crop is susceptible to number of fungal, bacterial and viral diseases that severely limit the productivity. A set of 92 diverse cowpea genotypes including varieties, mutants, advanced breeding lines, exotic and indigenous collections were serologically screened for resistance against Cowpea Aphid Borne Mosaic (CABM) virus using DAS-ELISA. The genotypes grown in triplicate in a randomized block design at Trombay were mechanically inoculated with CABM virus and the resistance or susceptible reactions of each of the genotypes were recorded visually as well as serologically. Based on the extent of symptoms and serological reactions, the cowpea genotypes were classified as: highly resistant, plants without symptoms and negative for serology; resistant, plants with mild mosaic (<25%) and positive for serology; susceptible, plants with mosaic (26-75%) and positive for serology and highly susceptible, plants with severe mosaic (>75%) and other systemic symptoms and positive for serology. The study resulted in the identification of 13 highly resistant, 24 resistant, 50 susceptible and 5 highly susceptible genotypes. The chlorophyll index of susceptible genotypes as measured by SPAD chlorophyll meter was almost half that of resistant genotypes. The highly resistant genotypes against CABM virus identified in the present study after due confirmation would be incorporated in the breeding programme to develop resistance in elite genetic backgrounds.

“…Cowpea is one of the major food legumes cultivated commercially in most tropics and sub-tropics and it is known to provide an important source of proteins for the rural poor farmers in developing countries (Bashir et al 2002). However, sufficient production of cowpea has been dwindled by several factors, but most importantly is due to prevalence and persistence of virus disease infection.…”

“…However, sufficient production of cowpea has been dwindled by several factors, but most importantly is due to prevalence and persistence of virus disease infection. Cowpea aphid-borne mosaic virus (CABMV) is considered an important constraint on cowpea crop in all agro-ecological zones, wherever it is grown (Emechebe and Lagoke 2000;Bashir et al 2002). The CABMV is economically important virus because it can cause yield losses exceeding 87 % under field conditions (Kaiser and Mossahebi 1975;Mali and Thottappilly 1986;Bashir and Hampton 1996;Shoyinka et al 1997).…”

Genetic inheritance of resistance to cowpea aphid-borne mosaic virus in cowpea

et al. 2012

Cowpea aphid-borne mosaic virus (CAB-MV) is a major virus disease in Uganda that causes substantial loss of the cowpea crop especially in growth and yield. The mode of gene action conferring resistance to the virus is not well understood. The objective of the study was to determine the genetic inheritance of resistance in cowpea crosses. Three susceptible (S) cowpea landraces that are commonly grown by farmers were crossed with five introduced resistant cowpea varieties in accordance with a North Carolina mating design II scheme. The F 1 , F 2 and BC 1 F 1 progenies generated were evaluated in the field together with their parents. They were then infected with two infection methods namely: by spreader-rows of S cultivar (Ebelat) and artificial inoculation of virus extracts. The results obtained showed that general combining ability (GCA) and specific combining ability (SCA) effects were significant, indicating that both additive and non-additive gene effects controlled virus infection. The results further demonstrated that the GCA effects (59.8 %) were more important than SCA effects (40.2 %) in determining virus resistance in the cowpea varieties. Utilisation of good general combiners of the varieties MU-93, IT82D-516-2, SECOW-2W and IT85F-2841 in hybridisation to improve virus resistance in cowpea crosses would be recommended. The result of this study provided an indication that CABMV resistance was conditioned by more than one recessive gene in eight populations, but also revealed resistance to be conditioned by a single recessive gene in the other seven populations. Observation of continuous distribution of progenies for severity data in the F 2 populations also confirmed significance of quantitative inheritance for CABMV resistance. Therefore, the significance of GCA effects suggests that recurrent selection could be applied to accumulate the additive genes for resistance in F 2 populations.
