Background dwarf bunt, which is caused by tilletia controversa kühn, is a soilborne and seedborne disease that occurs worldwide and can lead to 70% or even total losses of wheat crops. However, very little information is available about the histological changes that occur in dwarf bunt-resistant and dwarf bunt-susceptible wheat plants at the tillering stage (z21).

Karnal bunt (kb) of wheat, caused by tilletia indica, is one of the greatest challenges to grain industry, not because of yield loss, but quarantine regulations that restrict international movement and trade of affected stocks.

In this study, the microbial communities of wheat varieties resistant and susceptible to dwarf bunt, including wheat tissues of roots, ears, first stem under the ear, and stem base, as well as the microbial community in rhizosphere soil, were analysed.
The resistance of triticale was not reliably expressed in the glasshouse tests used, so selection for resistance to take‐all in a breeding programme would need to be conducted in the field. Individual pairs of rye chromosomes added to wheat did not significantly reduce its susceptibility.
Hand, a number of adapted resistant european wheat varieties are known, but often it is unknown which resistance genes are causing their resistance. Therefore, wheat breeding aiming to introduce bunt resistance into modern adapted material needs to base the breeding either on unadapted lines or adapted lines with unk-nown resistance genes.

Varietal resistance of wheat to bunt has been the subject of a number of investigations since that time, but these papers will not be reviewed here, as reed (17) recently gave a rather complete review. In addition to reed's paper, a very comprehensive investigation (19) of the relative resistance of wheat varieties to bunt was published in 1925.

For breeders, prioritizing multiple disease resistance in variety creation complicates and delays new releases compared to a single criterion like yield.
Karnal bunt (also known as partial bunt) is a fungal disease of wheat, durum wheat, and triticale. The smut fungus tilletia indica, a basidiomycete, invades the kernels and obtains nutrients from the endosperm, leaving behind waste products with a disagreeable odor that makes bunted kernels too unpalatable for use in flour or pasta.
