Effect of bean common mosaic virus on seed germination and yield of cowpea (Vigna unguiculata [L.] Walp.) breeding lines and characterisation of virus strains.

ABSTRACT: The study was conducted to characterise bean common mosaic virus strain Blackeye (BCMV-BICM) and determine the likelihood of seed transmission in cowpea breeding lines. F6 cowpea lines obtained from crosses between 'Ife-Brown' and 'IT-95 K-193-12' were planted at five locations in Southwest Nigeria for multilocational evaluation. Virus symptoms were observed on leaves of the breeding lines planted in Ibadan at eight weeks after planting. Enzyme-linked immunosorbent assay (ELISA) was used to determine the presence of six viruses: BCMV-BICM, cowpea aphid-borne mosaic virus, cucumber mosaic virus, cowpea mottle virus, southern bean mosaic virus and cowpea mild mottle virus. Seed transmission tests were carried out to determine virus transmission by seeds while growth and yield components of t
