Analysis of an F1-based incomplete diallel series of crosses involving 11 parents with different levels of resistance to Karnal bunt (Tilletia indica) revealed that GCA and thus additive or additive x additive gene effects were important for the inheritance of resistance, accounting for 87% of the variation. Further analysis concentrated on F3 lines derived from individual random F2 plants from crosses with resistant varieties having the highest negative GCA effects. The varieties Weaver and W499 possessed single dominant genes of resistance, which are distinct from each other, and which differed from a single allelic gene in varieties K342 and Cruz Alta. The majority of the crosses did not demonstrate a relationship between Karnal bunt infection and The number of days to heading in resistant F3 lines ranged from 80 to 100 days
