Evaluation of 58 pigeonpea cultivars and 61 accessions of Cajanus acutifolius, C. cajanifolius, C. grandifolius, C. lanceolatus, C. lineatus, C. mollis, C. platycarpus, C. reticulatus, C. scarabaeoides, C. sericeus, C. volubilis, Flemingia macrophylla, F. stricta, F. strobilifera, Rhynchosia aurea, R. bracteata, R. cana, R. densiflora, R. minima, R. rothii, R. suaveolens and R. sublobata in pot experiments revealed that the tested pigeonpea cultivars lacked resistance to H. cajani. Eight accessions of wild relatives were resistant and 20 accessions were moderately resistant. Based on the white cyst number of roots and low plant-to-plant variation, two accessions of C. scarabaeoides (ICPWs 111 and 128), three accessions of Flemingia spp. (ICPWs 194, 202 and 203), and one accession each of R. rothii (ICPW 257), R. densiflora (ICPW 224), and R. aurea (ICPW 210) were identified as resistant and promising for use in intergeneric hybridisation programmes
