Abstract
Lentil is an important legume crop of dryland
often affected by wilt caused by Fusarium oxysporum f.sp. lentis
posssing serious threat to economic yield in lentil growing regions of the
country, for ascertaining status of wilt in two districts of Uttarakhand and
Uttar Pradesh survey was done during 2012-13 and 2013-14 in which average wilt
incidence varied from 13.13% (Haldwani) to 24.79% (Bindukhatta). On evaluating
pathogenic variability among the isolates collected from different locations in
Uttar Pradesh and Uttarakhand during the survey, variation was observed in
pathogenic ability of the pathogen which ranged from 31.00 to 62.67 per cent,
thereafter isolates were categorized into four groups based on wilt incidence
where category ‘A’ had four isolates, category ‘B’ seven, thirteen and one
isolate in category ‘C’ and ‘D’ respectively.
