Exploring of bacterial blight resistance in landraces and mining of resistant gene(s) using molecular markers and pathogenicity approach.

ABSTRACT: Bacterial blight, one of the oldest and most severe diseases of rice poses a major threat to global rice production and food security. Thereafter, sustainable management of this disease has given paramount importance globally. In the current study, we explored 792 landraces to evaluate their disease reaction status against three highly virulent strains (BXo69, BXo87 and BXo93) of Xanthomonas oryzae pv. oryzae (Xoo). Subsequently, we intended to identify the possible candidate resistant (R) genes responsible for the resistant reaction using six STS (Sequence Tagged Site) markers correspond to Xa4, xa5, Xa7, xa13, Xa21 and Xa23 genes and finally, we evaluated morphological variability of the potential
