Wheat is an important cereal crop grown all over the world. There are many abiotic and biotic stresses which affects the yield of the crop. Out of this, diseases are the principal cause which is responsible for the decrease in yield. Karnal Bunt is the major disease which affects quality of food grain. Black Point is also becoming a serious problem in Punjab. The analysis of 140 grain samples collected from different grain markets of 8 blocks of Tarn Taran district in Punjab was conducted during 2018-2019. It was found that Karnal Bunt and Black Point disease was prevalent in all blocks. 86 and 80 samples of wheat were infected with Karnal Bunt and Black Point disease respectively. The prevalence of Karnal Bunt was more (92.30%) in Chohla Sahib block and Black Point was more prevalent in Valtoha (76.47%). The mean range of infection was more in Naushera Pannuan block (0.0 -12.7%) and Black Point was in Chohla Sahib block (0.0-2.3%). The disease incidence was correlated with the favourable climatic conditions during the heading stage of the crop. For determination of varietal variation it was found that Karnal Bunt incidence was more in HD 2967 (0.1-12.7%) in Naushera Pannuan block and Black Point gave maximum range of infection in HD 3086 in Bhikhiwind block. The disease incidence in recommended varieties was negligible. So, farmers were advised to grow recommended varieties of PAU which are suitable in Punjab agroclimatic conditions. In future regular surveys would be encouraged to identify the tolerant varieties which are grown in different blocks of Tarn Taran district of Punjab.
