Inheritance of resistance to bacterial blight (Xanthomonas oryzae pV. oryzae) in rice (Oryza sativa L.)
Main Article Content
Abstract
The mode of inheritance and allelic relationship among genes for resistance to bacterial blight (Xanthomonas oryzae pv. oryzae, iso-GR) in eight rice (Oryza sativa L.) cultivars was studied. The reaction of F1 and segregation pattern in F2 and F3 generations from the crosses of the test cultivars with MW-10, revealed the presence of single recessive gene in IR-54, R732-2-49-2-2, R744-1-107-2-2 and RP2151-33-2 and two independent recessive genes in R712-1-G5-2-2, R731-1-73-2-1, R738-1-G4-2- and R741-1-55-2-2. The resistant gene(s) present in these cultivars, segregated independently to Xa-1 gene of IRBB-1.
