Screening of Okra [Abelmoschus esculentum (L.) Moench] Genotypes for Yellow Vein Mosaic Virus (YVMV) Resistance Under Natural Diseases Pressure Condition

Sixty genotypes of okra along with pusa sawani as susceptible check were screened for YVMV resistance under field conditions. Per cent disease incidence and coefficient of infection were calculated for all the genotypes. Per cent disease incidence ranged from 10.0 to 100.0, where as coefficient of i...

Description
Summary:Sixty genotypes of okra along with pusa sawani as susceptible check were screened for YVMV resistance under field conditions. Per cent disease incidence and coefficient of infection were calculated for all the genotypes. Per cent disease incidence ranged from 10.0 to 100.0, where as coefficient of infection varies from 5.0 to 100.0. Out of 60 genotypes screened, seven genotypes were resistant (MHO -10, MHO -24, MHO -30, KRCO -3, KRCO -10, KRCO -15 and KRCO-28). Fifteen genotypes were moderately resistant(MHO-1, MHO-4, MHO-6, MHO -13, MHO -14, MHO-16, MHO -21, MHO -27, KRCO-13, KRCO -16, KRCO -18, KRCO -19, KRCO-21, KRCO-23, KRCO-30) and sixteen genotypes were moderately susceptible(MHO -12, MHO -18, MHO -20, MHO -22, MHO -26, MHO -29, KRCO-1, KRCO -4, KRCO -5, KRCO -7, KRCO -8, KRCO -9, KRCO -20, KRCO-22, KRCO-27, KRCO-29).Thirteen genotypes were found to be susceptible (MHO-2, MHO-3 , MHO -6, MHO -7, MHO -8, MHO -9, MHO -11, MHO -15, MHO -22 ,MHO -25 ,KRCO -12 , KRCO -14 , KRCO-24 , KRCO-26) and nine were highly susceptible (MHO -5, MHO -17, MHO -19, MHO -28, KRCO -2, KRCO -6, KRCO -11, KRCO -17, KRCO-25) .Resistant genotypes identified in the present study can be utilized further YVMV resistance breeding programme.
