Abstract:

A field experiment was carried out to screen 18 okra genotypes for YVMV resistance. The per cent plant infection and the reaction of the genotypes were assessed based on the disease incidence and response value assigned by each severity grade. Among 18 genotypes during 2014-15, minimum PDI was registered in VRO-6 (10.77 %) followed by IIVR-11 (12.50 %) and VRO-22 (19.05 %) while maximum PDI was recorded in Pusa Sawani (72.06 %) followed by EC-329357 (56.45 %). In second year of experimentation during 2015-16 also, minimum PDI was exhibited by genotype VRO-3 (8.73 %) followed by VRO-22 (15.66 %) and maximum PDI was exhibited in Pusa Sawani (77.15 %). It was observed that during both the years VRO-6 and IIVR-11 found resistance while Pusa Sawani found highly susceptible. During 2014-15, nine genotypes were assessed as moderately resistant, four moderately susceptible and two susceptible genotypes, whereas in 2015-16, five genotypes were moderately resistant, seven genotypes were moderately susceptible and two were susceptible.
