Abstract
Mungbean [Vigna radiata (L.) Wilczek] is the important source of proteins, minerals, and vitamins of the predominantly vegetarian Indian diet. Web blight caused by Rhizoctonia solani (Kuhn) is one of the most important fungal diseases which appear every year in varying intensity and causes heavy reduction in yield. The present investigations were carried out at the Student’s Instructional Farm (S.I.F.) A.N.D.U.A. &T., Kumarganj, Ayodhya to test the resistance of 100 genotypes against Rhizoctonia solani Kühn under natural conditions (In vivo).Genotypes were placed in different grades according to the rating scale which is based on disease severity. Out of total test entries nine genotypes viz., DGGV-2, OUM11-5, RMG1030, IPM9901-8, DGG1, SML10-82, MH2-15, LGG450 and CGG945 were found free from infection, twelve genotypes viz., RMG-975, CGG-973, AKM -8802, IPM -02-3, MH-4, Pusa -0672, AKM-4, CO-5 Check, Bbara S. check, Asha, BPMR 145 and IPM 02-14 were recorded highly resistant, twenty four genotypes were noticed susceptible and only nine genotypes were found highly susceptible.
