Identification of resistance against Fusarium oxysporum f.sp. lini in linseed germplasm

Screening of germplasm/varieties was made to find out the sources of resistance against F. oxysporum f. sp. lini. Screening was conducted on 78 available germplasm/varieties during 2003–2004 and 2004–2005 in rabi season of linseed under natural conditions. Out of total 78 entries, 27 cultures were found to be resistant to disease as the disease incidence in these cultivars were between 0 and 10%. Twenty-three cultivars fell in moderately resistant category with 10.1–25% wilt incidence. Nine genotypes were found moderately susceptible sho'wing 25.1–50% disease incidence, 14 genotypes were found susceptible showing 50.1–75% and 6 genotypes were found highly susceptible to disease (above 75%).
