In the present study genetic analysis of budfly resistance and yield components in linseed (Linumu sitatissimum L.) comprises of three lines and twenty testers crossed in LXT mating design and obtained sixty crosses were grown in randomized complete block design with two replications at College of Agriculture, Nagpur in rabi 2010-11. The row to row spacing was 30 cm with single row plot. The cultivar PKVNL-260 was grown on all sides of the block to avoid border effect. Data were recorded on five randomly selected plants of each family for the nine characters viz., days to maturity, plant height (cm), number of branches plant-1, number of capsules plant-1, budfly infestation (%), Alternaria blight infestation (%), powdery mildew, 1000 seed weight (g) and seed yield plant-1 (g).These selected lines of linseed (Linumu sitatissimum L.) were used to assess the budfly resistance and yield componentsand selection of potential parents and crosses for linseed breeding programme. Additive (D), dominance (H1), and epistasis components of genetic variation played an important role in the inheritance of days to 50% flowering, plant height, number of branches plant-1, number of capsules plant-1, 1000 seed weight, seed yieldplant-1, alternaria blight infestation(%) and budfly infestation (%). Simple recurrent selection should be utilized to capitalize the additive genetic variation for budflyresistance .The parents EC-14-24, Eita, EC-9825, EC-544, LCK-8605 and Neelum with maximum additive genetic variation will be useful for improvement of economic traits and may be utilized in hybridization programme.
