Association Between Resistance to Xanthomonas Oryzae and Morphological and Quality Characters in Induced Mutants of Indica and Japonica Varieties of Rice

Several induced mutants of IR-8 (indica variety) and Tainan-3 (japonica variety) were evaluated for resistance to bacterial blight, incited by Xanthomonas oryzae. Several leaf characters like rolled, narrow, dark green and slow senescence were associated with resistance. No consistent association between disease reaction and amylose and protein content in the grain was found.
