Abstract

Rice blast, caused by MAGNAPORTHE GRISEA Hebert (Barr.), is often an important constraint in RICE production areas. Attempts to utilize single resistance genes to control the blast disease have met with little permanent success. Accordingly, other breeding strategies are being considered, including the use of SLOW-BLASTING or quantitative resistance that reduces the disease severity. This study was undertaken to determine i) reaction of RICE genotypes from Iran to blast pathogen isolates and field population of the pathogen, ii) evaluation of components of resistance and rates of disease development (slow-blasting), iii) the area under disease progress curves, AUDPC, of the RICE cultivars used. Experiments were set as a randomized complete block design (RCBD), with three replicates in both greenhouse and field tests in RICE Research Institute of Iran in Rasht in 2003. Results showed that the reaction of 30 most popular RICE cultivars were differentially significant to different blast isolates. Cultivar x isolate interaction was also significant. In the upland nursery, disease progress varied greatly between the cultivars. The results suggest the presence of specific major gene(s) for resistance in RICE and virulence gene(s) in pathogen.
