Abstract:
One hundred fifteen genotypes/lines of Rice germplasm were screened against Blast disease under natural field conditions at Tripura centre lembucherra. The germplasm was categorized in to resistant and susceptible depending upon severity of disease. The present investigation aimed to identify resistant lines with high yielding through screening under natural condition. The experimental material consisted of 115 germplasm lines screened under field condition. Results revealed that most of the genotypes studied were categorized as resistant to moderatey resistant. Among 115 cultivars some are like Leproy, Znp upland, Gomini, Phougak (M-220), Kalajoha, RCM- 11 considered as resistant cultivars and the best genotypes with higher yield would be utilized as donors to develop resistant lines and these will be advanced for multilocational yield trial for selection as promising variety.
