Abstract:
The field experiment was conducted during Kharif 2021 at Shaheed Gundadhur College of Agriculture and Research Station, Jagdalpur, IGKV, Raipur (CG), to identify the resistant sources for blast disease (Magnaporthe grisea). Under the initial varietal trial twenty six genotypes evaluated with one resistant (GE4449) and susceptible (Udru mallige). Among them none of the genotypes were found to be resistant for leaf blast. However, genotypes IIMR-FM-7028, IIMR-FM-7835, DHFM-78-33, DPLM-3, BR-9, KMR-711, KOPN-1056 and VL-410 are exhibit the immune reaction against neck blast. In case of finger blast, it was ranged from 3.68% (IIMR-FM-7028) to 30.84% (DHFM-78-33), whereas the incidence was 15.39% in check. The mean of all location revealed that only four entries found to be promising for leaf blast resistant. The incidence ranged from 9.38 to 32.40 and 7.41 to 27.83 percent in finger blast and neck blast respectively.
