Twenty nine different genotypes/advanced breeding lines and four cultivars/checks viz., BR 11, BR 22, BR 25 and BRRI dhan 38 of rice were selected for the study to examine and screen out the advanced hybrid lines, which are resistant/tolerant to brown spot and blast disease. One accession showed resistant (R) reaction in T. aman season and twenty-nine cultivars showed moderately resistant (MR) reaction in boro season to brown spot. Thirteen accessions were found as moderately resistant (MR) in T. aman season and three breeding lines/genotypes were found to be highly resistant (HR) and five were resistant (R) in boro season to blast. So, these lines/cultivars may be used as breeding materials and cultivated for rice production.
