Abstract

An experiment was laid out in Randomized Block Design with three replication to screen twenty five genotypes under sick plot condition. The screening of new resistance to isabgol genotypes against this disease is an alternative approach to avoid indiscriminate use of pesticides. Out of twenty-five genotypes screened, one genotype ‘UI 25’ was resistant, while eight genotypes UI-11, UI-17, UI-24, UI-62, UI-121, UI-125, HI-2, UI-124 were moderately resistant. However, GI 2 showed susceptible reaction and rest fifteen genotypes were found moderately susceptible against wilt of Isabgol.

Conclusion

In the current study, an effort was made to screen twenty five different genotypes of isabgol for source of resistance against wilt under sick plot condition. Out of twenty five genotypes screened, one genotype was resistant and eight genotypes were moderately resistant. However, genotype GI 2 showed susceptible reaction and rest fifteen genotypes were found moderately susceptible reaction against wilt disease. For effective disease management, continuous screening of genotypes is advised, focusing on potential breakdown of resistance source of major races in isabgol growing regions.
