Abstract:
Rice is a staple food crop for majority of the world's population, including almost all East and Southeast Asia. Rice cultivation was affected by various biotic and abiotic stresses, which still represent the major obstacles to a sustained growth in rice production. Bacterial leaf blight (BLB) caused by disease of Xanthomonas oryzae pv. oryzae (Xoo). BLB is a most devastating biotic disease in rice which results in 20%–30% annual decrease in rice crop production in Asia. In the view of rapidly growing world’s population, there is an imperative need to improve the potential yield in rice has been the main concern in rice breeding programs worldwide. Sustained increase in rice production has to overcome increasing yield loss due to emerging pests and diseases. The use of a resistant cultivar is the most effective and environmental friendly method to combat the disease. In the present study, a diverse set of 100 accessions from the 3K RG panel were evaluated for the allelic variation for the Bacterial leaf blight (BLB) responsiveXa21gene. In this study, four haplotypes (H1, H2, H3 and H4) were identified for Xa21 based on five non synonymous SNPs.
