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
