Narrative
Erect, indeterminate compact cowpea with heat tolerance during flowering and resistance to Races 3 and 4 of Fusarium wilt (Fusarium oxysporum) and root-knot nematodes (Meloidogyne incognita and M. javanica). Carries gene Rk and a recessive gene that together protects against Rk-virulent M. incognita and M. javanica. Reproduction and root-galling due to Rk-virulent M. incognita and M. javanica are about half those observed on cultivars CB46 and CB88. Begins flowering in about 52 days from sowing and the first flush of pods is mature in about 95 days when planted in early May in the San Joaquin Valley, CA. Average seed weight 224 mg/seed. Seed coat bright white and medium black 'eye'. Excellent canning quality.
