Abstract

Nature and mode of inheritance of bacterial leaf blight (BLB) resistance of rice cultivar, Ajay (IET4141-CR98–7216) was studied against a highly virulent culture of Xanthomonas oryzae pv. Oryzae from Northern India corresponding to pathotype II reported earlier from India. The segregation pattern for BLB reaction in F2 and F3 generations from the cross of cultivar Ajay with the susceptible cultivar, Taichung Native I suggested that BLB resistance in cultivar Ajay is controlled by independently inherited duplicate genes. No relationship was observed between any polymorphic isozyme of either peroxidase or esterase and BLB resistance gene(s) in cultivar Ajay.
