Artificial epiphytotic conditions were created by the tooth-pick method. Despite significant genotype × environment interactions varietal differences persisted. There was no host immunity but SPV-34, CSH-9 and 36B among the improved lines developed at the All-India Coordinated Sorghum Improvement Project and 6-39, 8-55 and SC 120-14 among the basic stocks were highly resistant. CSH-9, 36B and 6-39 were av. and 8-55 and SC 120-14 were above av. in stability of disease resistance. The seasonal change in host plant resistance of some of the cultivars appears due to their photoperiodic sensitivity Indian Phytopathological Society 1983 Article PeerReviewed application/pdf en http://oar.icrisat.org/5575/1/0801.pdf Indira, S and Rana, B S and Reddy , B B and Rao , N G P (1983) Stability of host plant resistance to sorghum charcoal rot.
