Abstract

Wheat is the important cereal and is highest produced grain in the world after corn and rice. It is the second most important crop in India next to rice. Like several crops, wheat is also prone to diseases. Among various diseases, wheat stem rust is the main biotic constraint to wheat production and it is important to understand and analyze the disease in terms of pathological responses. Out of six cultivars tested, three wheat varieties showed a resistance response, while the other three varieties showed a susceptible response against stem rust of wheat. Disease severity and area under disease progressive curve (AUDPC) data of three susceptible varieties revealed that the highest AUDPC value (1785.93) was recorded in A-9-30-1 which showed the most susceptible response followed by Agra Local (1762.93) and Kharachia (1645.90). There was no development of stem rust symptoms on three varieties viz., GDW 1255, GW 496 and GW 451.
