Abstract

The present investigation was carried out in artificial conditions of College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner (Rajasthan), India during the year 2016-17 and 2017-18. Forty genotypes/varieties of chickpea were screened for reactions against Sclerotinia rot, caused by soil-borne Sclerotinia sclerotiorum under artificial conditions. Out of forty genotypes/varieties of chickpea screened, none was found completely free from S. sclerotiorum infection. None of genotypes/varieties were found moderately resistant (MR) to Sclerotinia rot. Whereas, four genotypes/varieties i.e. GNG-1581, RSG-888, RSG-973 and H-208 were categorized as moderately susceptible (MS) and thirty five genotypes/varieties i.e. GNG-1958, GNG-663, GNG-469, GNG-1969, GNG-1488, GNG-1499, RSG-44, RSG-945, RSG-807, C-235, GNG-146, GNG-1292, CSJD-884, RSG-895, RSG-991, RSG-896, RSG-902, RSG-974, CSJK-21, GNG-2144, Dohad Yellow, K-850, L-550, RSG-584, GNG-2171, ICC-96030, JKG-1, ICC-16644, ICC-17109, BG-379, Chaffa, Radhey, BG-2078, BG-256 and HK-98-155 were assessed as susceptible (S). Rests of RSG-963 genotypes/varieties were recorded as highly susceptible (HS) to S. sclerotiorum infection in chickpea during Rabi 2016-17 and Rabi 2017-18. Development of resistance or tolerant chickpea varieties to Sclerotinia sclerotiorum is challenging since the pathogen is having a wide host range. Hence, knowledge of pathogenic variability is essential in making strategies for developing disease resistant varieties and development of resistant gene in the region.
