Sheath rot of rice, Sarocladium oryzae [(Sawada) W. Gams & D. Hawksw], is currently regarded as
one of the most serious rice diseases in Fogera plains. Varietal resistance is the most cost-effective and eco-friendly
management strategy for the small-scale farmers. An investigation was conducted to identify resistant sources among
rice germplasm introductions that could be employed in varietal development program. Eighty germplasms along
four checks were evaluated in field trials for two years at two locations arranged in an augmented design. Results
indicated that three immune germplasms (SCRID014-1-1-1-1, SCRID037-4-2-2-5-2 and YUNLU N0.33) were found
to be suitable for resistant variety development. The remaining, germplasms were found to exhibit different levels
of reactions, of which 27 resistant, 35 moderately resistant, 13 moderately susc.. View more»
