A simple pot culture technique was used to screen 2,835 pigeon pea (Cajanus cajan) accessions and cultivars and seven Atylosia spp. for resistance to Phytophthora drechsleri f. sp. cajani. Seventy-seven germ plasm accessions, three cultivars, and two species of Atylosia were found to be resistant. The resistance of 75 of the accessions and cultivars was confirmed under field conditions.
