Inheritance of resistance to blackeye cowpea mosaic virus in White Acre-BVR' cowpea
HortScience 26 (2), 194-196
Abstract: Reciprocal crosses were made between 'White Acre-BVR', resistant to blackeye cowpea mosaic virus (BICMV), and the susceptible 'California Blackeye No. 5' cowpea [Vigna unguiculata (L.) Walp.]. Seedlings from 'California Blackeye No. 5', 'White Acre-BVR', F₁, F₂, and backcrosses were mechanically inoculated with BICMV, and evaluated 4 weeks later for symptom expression in the greenhouse. Plants were assayed by enzyme-linked immunosorbent assay. The resistance observed in the F₁ and progeny from the backcross to the resistant parent indicated that resistance to BICMV in 'White Acre-BVR' was dominant. Furthermore, a 1 resistant: 1 susceptible segregation of progeny from the backcross to the susceptible parent and a 3 resistant: 1 susceptible segregation of the F₂ progenies suggested that the resistance to BICMV in 'White Acre-BVR' was conferred by a single dominant gene.
