Experiments involving artificial inoculation and enzyme-linked immunoabsorbent assays (ELISA) were conducted to investigate the latent infection of Burkholderia solanacearum and their variation among resistant groundnut genotypes. Frequencies of latent colonization varied among genotypes. Low latent colonization was detected in a few resistant lines which possessed resistance to bacterial wilt across seasons and locations. Genotypes with high latent colonizations were more sensitive to drought stress in late growth stages, even when wilt incidence was low. Hypocotyl tissues supported the highest bacterial colonization frequency. Improved techniques to detect latent colonization and evaluate resistance have been developed
