Abstract
Abstract A single recessive gene, blc, controls resistance to blackeye cowpea mosaic virus (B1CMV) in progeny from a cross between southernpea (cowpea) cultivars ‘Worthmore’ (homozygous resistant) and ‘California Blackeye No. 5’ (homozygous susceptible). All F1 plants and backcrosses to the susceptible parent were susceptible, indicating that resistance is recessive to susceptibility. Backcrosses to the resistant parent segregated 1 susceptible: 1 resistant and F2 plants segregated 3 susceptible:1 resistant.
