Abstract:
The study was conducted in Kharif 2019 at Research cum instructional Farm S.G. College of Agriculture and Research Station, Kumhrawand, Jagdalpur, Bastar IGKV Raipur (C.G.). To evaluate 85 accessions of finger millet genotypes were screened to identify the sources of resistance against blast, diseases. In screening of blast disease incidence, all three patterns namely leaf blast, neck blast and finger blast were recorded. For leaf blast incidence, only one genotype i.e., IC0477045 exhibited resistance. Among others, moderately resistant (30 genotypes), moderately susceptible (32), susceptible (15) and highly susceptible (7) reaction was seen. Neck blast disease incidence ranged from 17.8% to 66.0% indicated that none of the genotypes showed resistance against neck blast. 1 (one) genotypes IC0477787 were found to be moderately resistant, 9 genotypes Moderate susceptible, 51 genotypes susceptible and 24 genotypes highly susceptible. When plants began maturing, they were screened for finger blast disease where none of the genotypes were found to be resistant against the disease, and the percentage of infection ranged from 19.7% to 67.6% compared to 98.8% in susceptible check (GPU 28, Indira Ragi-1, GPU 67, CG Ragi -2). Among the genotypes evaluated Moderate resistance was observed in case of 4 genotypes viz. GEC247, IC0477673, GEC 396, and IC0587989. Moderate susceptible 23 genotypes, 48 genotypes susceptible and 10 genotypes exhibited highly susceptible reaction against finger blast disease.
