Evaluation of Donor Screening Nursery (DSN) of finger millet against Rhizoctonia solani, the cause of Sheath blight

Abstract

The present investigation was undertaken to evaluate the resistant genotypes amongst 21 varieties of finger millet against major diseases during kharif, 2017 at Agricultural Research Station, Vizianagaram, Andhra Pradesh. Among them none of the variety could exhibit the immune reaction, in which nine varieties are found to be highly resistant and four varieties are resistant whereas DAPOLI-I recorded as highly susceptible to leaf blast. The percent disease incidence of neck blast ranged from 18.84 (GPU-28) to 60.45 (GPU-45) where it was 91.07 in susceptible check VR 708. In case of finger blast, it was ranged from 12.46 (GPU-26) to 61.15 (Indaf-7), whereas the incidence was 93.78 in check. The mean of all locations revealed that three varieties are found to be resistant to leaf blast. The incidence ranged from 18.84 to 61.24 and 12.46 to 61.64 in neck blast and finger blast respectively.
