Abstract:
Pot studies under net house conditions of Department of Nematology, OUAT, BBSR were conducted in 2015 and 2016 to evaluate the reaction of 149 germplasm of urd bean for resistance against Meloidogyne incognita. After 45 days of inoculation, the roots of all the germplasm were assessed to determine gall indices on a 0-5 scale. After 45days data were recorded on the basis of nematodes reproduction. Out of one hundred fortynine (149) germplasm none was found immune against root knot nematode. Nineteen (19) germplasm RU-1-9-1, KUG-715, NUL-205, TU99-5-1, UG-950, DBG-17, NDU 99-2, OBG 19, KU 96-3, IU 02-1-3, VBG 11-031,TU 94-2, AKU-11-8, MASH-479, MASH-391, KUG-715, NUL-205, PU 11-14, VBG-11-016 were categorized as resistant against M. incognita while twenty four (24) germplasm DPU-88-5, KU 99-4, OBG-630, TPU-4, UG 1017, USJD111, KU 99, PU 09-37, COBG 1-06, TU-67, NUL-244, DPU-88-2, NDU-88-9, WBU-104, BDU-1, Phule-U-0011-1, KU-12-53, SBC-47, AKU 10-2, AKU 10-6, KU-96-7, DKU-11, NDUK-13-6, KU-96-7 were categorized as moderately resistant against M. incognita and rest germplasm were found susceptible and highly susceptible reaction to nematode.
