ABSTRACT
This study was carried out to assess the extent of variability for yield and yield related traits in upland rice genotypes. Twenty-two selected rainfed upland rice varieties were evaluated in randomized complete block design with three replications during 2014 cropping season. The analysis of variance revealed significant differences between the genotypes for all traits except harvest index, indicating the presence of a considerable amount of variability among the genotype. The disease reaction of different genotypes showed a significant variation for blast and brown spot. The highest disease severity was scored by variety Andaasa which is moderately susceptible to leaf blast. Tana, Andassa, Getachew, FOFIFA-4129 and FOFIFA-3730 showed moderately susceptible response to panicle blast. Severity of brown spot ranged from 1.13-6.03. The highest disease severity value was scored by variety Andasa followed by Tana, Getachew and FOFIFA-3730 which showed moderate resistance to brown spot.
