Screening of Linseed Germplasm Against Wilt, Fusarium oxysporum F. sp. Lini for Identification of New Source of Resistancek

An experiment on screening of 200 linseed germplasms was conducted during Rabi 2013–14 at the experimental field of Research cum Instructional Farm, I.G.K.V., Raipur, Chhattisgarh, India to find out the new source of resistance against linseed wilt Fusarium oxysporum f. sp. lini. The observations were recorded on the basis of per cent mortality at 20, 40 and 60 days after sowing. Results revealed that the germplasm mortality per cent varied from 7.49 per cent (Es-16318) to 98.79 per cent (H-11). Two germplasm lines were exhibited resistant category Es-163118 and KL-227 (below 10% mortality). Remaining 18, 28, 70 and 82 germplasm grouped under the category of moderately resistant (10.1 to 25.0%), moderately susceptible (25.1 to 50.0%), susceptible (50.1 to 75.0%), and highly susceptible (75% and above), respectively.
