Abstract:
Chickpea collar rot caused by Sclerotium rolfsii is considered economically important soil borne disease. A total of 20 Chickpea advanced breeding lines supplied by Chickpea Breeder, RARS, Nandyal were screened under field conditions (Screening blocks) against collar rot. L-550 was used as a susceptible check. The observations viz., total number of plants and total number of infected plants were recorded up to up to 30 days after sowing and Percent disease incidence of collar rot was calculated. Among 20 advanced breeding lines, 6 lines (NBeG 1267, NBeG 440, NBeG 690, NBeG 779, NBeG 699 and NBeG 776) were showed resistant reactions with 0-10 per cent disease incidence, 10 lines were found to be moderately resistant reactions, 2 lines were reacted as moderately susceptible reaction, 2 lines were showed susceptible reaction and L 550 showed highly susceptible reactions.
