摘要

The level of resistance of 12 Bangladeshi modern rice cultivars along with M95 (radiation induced mutant of the Japonica rice cultivar "Harebare"), TKM6, and IR24 to five major Japanese and 13 Bangladeshi races of Xanthomonas oryzae pv oryzae (X. oryzae pv. oryzae) was determined. Among the tested materials, the induced mutant M95 and the boro (January to May growing season) rice cultivar BRI 4 showed resistant reactions to all of the five Japanese races (races I to V) of X. oryzae pv. oryzae. The aman (July to December growing season) rice cultivar BrridhanSS showed resistant reactions to the Japanese races I, II, HI, and V. The induced mutant M95 also showed high level of resistant reactions to all the 13 Bangladeshi races of X. oryzae pv. oryzae,indicating the non-specific, horizontal or quantitative nature of resistance to both Japanese and Bangladeshi races. The cultivar Brridhan33 showed resistant reactions to ten Bangladeshi races 1 to 5, 9,10, 14,17, and 23 of X. oryzae pv. oryzae. Host-pathogen interactions were highly significant (P>0.01), indicating the existence of the race specific or vertical resistance of the Bangladeshi rice varieties to the major Japanese and Bangladeshi races. The virulence of some Bangladeshi races on some ricevarieties was higher than those of the Japanese race. The resistance genes from M95, BRI4, and Brridhan33 will be useful in the development of durable BLB resistant rice cultivars in Bangladesh, Japan, and other Asian countries.
