Abstract:
Linseed (Linum usitatissimum L.), also known as flax, is a member of the family Linaceae. The essential oils are Angiosperm plants species including herbs, shrubs, and tree; extracted by Clevenger Hydro distillation method. So, the present study was undertaken to evaluate the effects of some eco-friendly essential oils against Fusarium oxysporum f. sp. lini, by which we can improve the agricultural production of linseed. Screening of germplasm/varieties was made to find out the sources of resistance against F. oxysporum f. sp. lini. Screening was conducted on 46 available germplasm/varieties during 2019–2020 and 2020–2021 in rabi season of linseed under natural conditions. Out of total 46 entries, 1 cultivars were found to be resistant to disease as the disease incidence in these cultivars were between 0 and 10%. 12 cultivars fell in moderately resistant category with 10.1-25% wilt incidence. 8 genotypes were found moderately susceptible showing 25.1-50% disease incidence, 8 genotypes were found susceptible showing 50.1–75% and 17 genotypes were found highly susceptible to disease (above 75%).
