 ABSTRACT

Pigeonpea [Cajanus cajan (L.) Millsp.] is second most important legume crop after chickpea in India and it is predominantly grown during the Kharif season both as a sole and intercrop under wide range of agro-ecological situations. The crop is suffers from several diseases among them, dry root rot incited by Rhizoctonia bataticola is the major threat in pigeonpea cultivation. Attempts were made to find out resistance source by screening 33 genotypes comprising of released and MLT lines under glass house condition at MARS, Raichur by using paper towel technique. Out of 33 genotypes screened, 11 showed resistant reaction viz., GRG-177, GRG-811, TS-3R, ICP-14832, BDN-2008-8, GRG-820, AGL-1666, AGL-1919, AGL-2013, ICP-8793 and AGL-1603. Whereas AKT-9913, GRG-2013, GRG-222, BDN-2008-1, Maruti, ICP-7223, GRG-444 and ICP-88039-1 grouped as moderately resistant and remaining 13 genotypes viz., GRG-151, GRG-152, NTL-900, ICPL-14001, ICP-16264, GRG-140, ICP-13673, GRG-111, ICP-11320, ICP-13101 TDRG-33, AGKL-2249 and ICPL-99050 were susceptible to dry root rot disease.
