Screening of Cowpea Genotypes for Resistance to Afacrvphomma phaseolina Infection using Two Methods of Inoculation

摘要

Five cowpea cultivars, IT03K -316-1, IT04K-217-5, IT06K-154-1, IT99K-216-44 and IT03K-369-3, obtained from the International Institute of Tropical Agriculture, Ibadan were screened for resistance to Macrophominaphaseolina infection using two methods of inoculation viz, pouring of spore/mycelia suspension in the soil and wrapping of inoculum meal around wounded lower stem of the seedlings. Cowpea cultivar IT04K-217-5 was resistant to the pathogen in both inoculation methods while the other four cowpeacultivars i.e., IT03K-316-1, IT99K-216-44, IT06K-154-1 and IT03K-369-3 showed varying degree of susceptibility to the pathogen in both inoculation methods.
