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