Screening of Linseed Germplasm for Resistance/Tolerance against Fusarium oxysporum F Sp. Lini (Bolley) Disease

Absence of resistance/tolerance against diseases and insect pests in linseed (Linum usitatissimum L.) varieties is one of the main reasons for their low yield in India. During the summer season, Fusarium oxysporum f sp. lini epidemic damage the crop in most of the linseed seed growing area. For the purpose of identifying resistance/ tolerance in linseed germplasm, a disease screening in trial, comprising of 200 test entries was developed. Screening was done under natural conditions in 2012 at C.S.A. University of agriculture and technology Kanpur. Out of 200 germplasm, 116 resistances, 51 moderately resistant, 30 moderately susceptible, 3 susceptible and 1 germplasm highly susceptible were found.
