Karnal bunt of wheat, caused byNeovossia indica (Mitra) Mundkur, was first reported in 1931 from Northwestern India in experimental plantings. For many years it was a minor disease found only in Northwestern India. During the 1969–70 crop season it was unusually widespread in Northwest India and since 1974–75 Karnal bunt has been distributed throughout Northern India from West Bengal to the western border. Seed lots with more than 50% of the kernels infected have been collected from farm… Expand

Karnal bunt of wheat: Etiology, breeding and integrated management
TLDR
The chromosomal assignments for QTL/genes controlling Karnal Bunt resistance in common wheat identified through the Genome Wide Association mapping studies (GWAS) is constructive in pre-emptive breeding against the pathogen in wheat produncing areas that are free from the disease. Expand
Status of Karnal Bunt in Major Wheat Growing Regions of Northern Haryana
TLDR
The range of Karnal bunt was between 0.05 – 4.70 per cent in these districts which was exceeding the permissible limit of Indian Minimum Seed Certification Standards (0.25%) for quality wheat seed production. Expand
Towards a more reasoned assessment of the threat to wheat crops from Tilletia indica, the cause of Karnal bunt disease
TLDR
Arguments in this and previous reviews advocating a more reasoned and comprehensive assessment of the threat to Europe, North America and other locations from T. indica need to be taken into consideration in any new pest risk analyses. Expand

TLDR
It is suggested that heterothallism and nonpaired monosporidial lines of the Karnal bunt fungus pathogenicity are controlled by multiple alleles at one locus; (Tilletia indica) were used to inoculate wheat heads in the four such alleles demonstrated in the material studied. Expand
