| Abstract |
Karnal bunt (KB) or partial bunt is the most recently described smut disease of wheat (Mitra 1931, Mundkur 1943b, Bedi et al. 1949). It was first reported in 1931 in experimental wheats at the Botanical Station at Kamal, India (Mitra 1931) and was for many years known only in the plains of India and Pakistan. However, since 1974 it has been noted in many locations across northern India. KB differs from other smuts of wheat in that the pathogen, Tilletia indica, infects during anthesis, unlike T. caries, T. foetida, T. controversa, and Urocystis agropyri, and it sporulates on the same generation of the host that it infects, unlike Ustilago tritici. |
