Abstract:
The reactions of 10 near isogenic lines and 10 pyramiding lines possessed single or combination of
Xa genes for resistance to
Xoo. Obtained from International Rice Research Institute Hyderabad and seventeen local variety were evaluated for the resistance to three different isolates in Chhattisgarh Under
in vivo condition among the NIL’s IRBB-10 carrying
Xa10 resistant gene for
Xanthomonas oryzay pv. Oryzae expressed resistant to Raipur and Kanker isolate while moderate resistant to DRR and Dhamtari isolate and IRBB-8 and IRBB-11 expressed resistant to only Raipur isolate. The rest NILs showed susceptible to moderately susceptible reaction to all the isolates In the present investigation the host specific nature / incompatible interactions of the isolates on the near isogenic lines indicated that responses are clearly the result of the molecular cross talk between avirulence gene product(s) and corresponding R gene product(s) the pyramiding line containing two to three resistance gene combination IRBB-52 (
Xa 4 + Xa 21 ), IRBB-54 (
xa 5 + Xa 21 ), IRBB-57 (
Xa 4 + xa 5 + Xa21 ) and IRBB-58 (
Xa 4 +xa 13 + Xa 21 ) were
expressed highly resistant reaction to Raipur isolate and moderate resistant to resistant reaction to the most of isolates collected from different geographical location of Chhattisgarh. Local varieties were more susceptible than improved varieties to leaf blight disease. Among Local varieties, H.M.T., Pant-4 and Safri-17 was the most susceptible and Maheshwari was resistant to
Xoo isolate. The overall results indicated that resistance gene(s) behave differentially against different isolates. The combination of genes some time exhibited additive resistance while non-additive in some combination and against different
Xoo cultures.
