Abstract

Inheritance and allelic relationships of genes for resistance to rice bacterial blight present in 3 donor strains were studied. A single recessive gene in RP2151-33-2 and BG400-1 and two complementary dominant genes in S. 971 for resistance were detected. Allelic studies indicated that the genes for resistance present in these donors were different from the already reported genes Xa-1, Xa-2, Xa-3, Xa-4, Xa-5, xa-7, u-S, Xa-10, Xa-11 and Xa-1h.
