Abstract

Bacterial leaf blight (BLB) of rice is a major disease caused by Xanthomonas oryzae pv. oryzae, limiting rice production in rice growing regions of the world. Safri-17 is high yielding rice variety of Chhattisgarh but it’s highly susceptible to BLB. Three major resistance genes, viz., Xa21, xa13 and xa5, are deployed in Safri17 variety either singly or in combinations from a donor line RP-Bio226. Genetic analysis was done using linked molecular markerincludes pTA248 for Xa21gene, xa13-prom for xa13 gene and xa5 S+R for xa5 gene to confirmed the presence of three genes governing BLB resistance. Breeding lines with two or three resistance genes were developed and tested for resistance towards BLB.They showed a wider spectrum and a higher level of resistance as compared to lines with only a single gene.
