Effects of global warming, increase in temperature, humidity and cultivation techniques for higher grain yields cause an increase in black point disease incidence and severity. The goal of the study was to determine the extent of disease reactions to some bread wheat cultivars against black point disease. The experiment determined effect of parents on the incidence and severity of infection on the segregating populations at F4 and F5 levels during 2022–23 and 2023–24 growing seasons at Yerköy location. The average incidence and severity of black point were 4.41 and 1.29% in the first growing season which rose to 12.54 and 2.80% in the second growing season, in the same sequence. The high incidence and severity of the disease on all genotypes in the second growing season were more favorable for the occurrence of black point. The moderately susceptible cultivars were Bayraktar 2000 and Adali while Rebelde, Halis and Taner were highly resistant. In the F4 and F5 segregating populations of the crossed cultivars, the incidence of black point was found in between the incidence observed on their parents. It was determined that Adali transferred its susceptibility, whereas Rebelde transferred its resistance to segregating population progenies to a great extent. Backcrossing for a few generations to increase the resistance of the crosses can also be considered as a method to improve resistance against the disease. It would be useful to screen the parents and progenies for their susceptibility to black point before chalking out wheat breeding programs.
