Centenary of Soil and Air Borne Wheat Karnal Bunt Disease Research: A Review.

ABSTRACT: Karnal bunt (KB) of wheat (Triticum aestivum L.), known as partial bunt has its origin in Karnal, India and is caused by Tilletia indica (Ti). Its incidence had grown drastically since late 1960s from northwestern India to northern India in early 1970s.
