The present study was undertaken in 2017 cropping season at the Screen House of Niger State College of Agriculture, Mokwa to investigate the effects of inoculating five cowpea cultivars: "Langbazo”, “Ezomilkigi”, “Ezobokun”, “Ezokapangi” and IT07K-277-2 with Cowpea mottle virus [CPMoV], genus Carmovirus on their growth performances. The trial was laid out in Complete Randomised Design [CRD] with five treatments and an uninoculated control and set up in three replicates. Results show that growth parameters of the buffer inoculated control plants were significantly higher than those of the virus inoculated. The average values of plant height and number of leaves produced by cowpea cultivars Langbazo and IT07K-277-2 were significant compared to the other treatments. The resistant traits from Langbazo and IT07K-277-2 can be incorporated with high yielding genotypes to develop CMoV resistant varieties. Further studies are needed to screen the cultivars on their defense abilities for use in hybridisation studies.
