Screening of Finger millet for major diseases and identification of resistant varieties

Abstract

The present investigation was undertaken to evaluate the resistant genotypes amongst 30 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 five varieties are found to be highly resistant and nineteen varieties are resistant whereas VR 708 recorded as highly susceptible to leaf blast. The percent disease incidence of neck blast ranged from 13.67 to 84.13 where it was 91.11 in susceptible check VR 708. In case of finger blast, it was ranged from 11.58 to 82.56, whereas the incidence was 92.26 in check. The mean of all locations revealed that seven varieties are found to be resistant to leaf blast. The incidence ranged from 19.98 to 69.04 and 18.20 to 50.77 in neck blast and finger blast respectively.
