The present investigation was conducted at the College of Agriculture, Raipur (C.G.) to Evaluation of linseed germplasm for response against linseed Bud fly (Dasyneura lini Barnes). The field trial was conducted under natural condition to screen hundred germplasm of linseed against bud fly in two consecutive years (2020-21 and 2021-22) during rabi season I.G.K.V., Raipur, Chhattisgarh. Linseed (Linum usitatissimum L.) is an important ancient oilseed crop grown for its seed oil or fibre or for both purposes (dual purpose flax) across the world. Among several management options, use of resistant variety is the most practical and economical method of pest management. Therefore. On the basis of pooled analysis, the average budfly infestation varied between 6.66 percent (LCP-147) to 76.46 percent (KLS-D-9). Out of hundred germplasm fourteen germplasm namely LC-2279-4, BAU-06-5, PCL-12-3-06, LMS-3, JLT-204, OLC-99-57, LCP-147, SLS-74, RLC-120, RL-2600, OL-98-15-12, PKDL-95, NDL-2009-17, and KLS-C-5 were categorized under resistant category. Sixty six germplasm were categorized under moderate resistant category. Fifteen germplasm namely RRN-5, RRN-7, LCP-146, LMS-2007-1, LMS-23-6, KLS-B-1, KLS-C-1, KLS-C-4, KLS-C-6, KLS-D-5, RRN-2, RRN-4, PKDL-62, PCL-35-06 and RLC-115 were categorized under moderate susceptible category. Two germplasm were categorized under susceptible category namely PKDL-65 and RLC-121. Three germplasm namely NL-126, KLS-D-9 and KLS-D-3 were categorized under highly susceptible category.
