Abstract: Under the changing weather conditions Dirty Panicle Disease is observed as a major problem that that indicates poor grain quality and reduces appeal to the consumers on account of grain discolorations. The prevalence of dirty panicle disease was determined in 12 most commonly cultivated rice varieties during Kharif 2017 & 2018 under agro-climatic conditions of Madhya Pradesh. Maximum panicle infection and seed discoloration (30%) was noticed in IR 64 followed by IR 36 (28%) and Kranti (22%). During second week of November the temperature ranged 11.9 to 28.3 C and relative humidity upto 87% at pre-harvest stage in the samples from 13 districts covering 6 agro-climatic zones. Incremental development of the disease indicate that at 50% grain filling stage during 3rd week of October 2017, incidence of the disease was upto 12.0% that enhanced to 19.0% during November 1st week (at 90% grain filling stage). Analysis of seeds from dirty panicle disease indicates that maximum percentage of (36.45) was recorded in IR 64 followed by 33.75% in IR 36 and least 28.87% in Kranti.
