Abstract :

MTU1010, the popular mega rice variety was used as a recurrent parent for improving the Bacterial blight (BB)

and blast resistance. Improved Samba Mahsuri (ISM) and NLR145 were used as donors for source of resistance
genes of BB and blast respectively. Before using the donor and recurrent parents in crossing programme for generation of eeding material,
the parents must be validated for the presence of resistance genes using respective gene targeted markers.The results revealed that the STS
marker pTA248 was linked to Xa21 whereas xa13 promoter linked to xa13 gene, the results also indicated that markers are RM206, Pi54 MAS
were linked to Pi54 gene. These resistant and susceptible alleles shown in accordance with earlier reports
