Abstract

Present study on screening of urdbean germplasm for resistance against Rhizoctonia solani kühn causing web blight disease revealed that in detached leaf technique, 42 genotypes of Urdbean were evaluated for web blight resistance. Out of these fourteen genotypes i.e. IPU-2-43, KPU-1-10, KU-1106, CoBG-10-5, LBG 752, VBG-10-024, NUL-7, ACM 05007, Uttara-3, UH-08-05, UH-07-06, CoBG-761, NDU-11-202 and KUG-580 were found moderately resistant to web blight. During field screening in 2011 and 2012, lines LBG-752, VBG-10-024, NUL-7, ACM-05-007, Uttara-3, UH-08-05, UH-07-06, CoBG-761, NDU-11-202, KUG-586, IPU-2-43, KPU-1-10, KU-1106 and CoBG-10-5 showed moderately resistant reaction to web blight disease and rest of the lines shows susceptible reaction.

Screening of Urdbean germplasm for resistance against Rhizoctonia solani kühn causing web blight disease

Methods of screening used were detached leaf technique (in vitro) and field screening (in vivo)
