Correlation Between Wheat Seed Color And Fusarium Head Blight Infection

During 1997-98 Cropping season, 121 genotypes of wheat at Sari Agricultural Research Station and 189 genotypes at Gorgan Agricultural Research Station were evaluated for their reaction to Fusarium head blight (FHB). Studies were conducted to determine correlation between seed colors (white white, white, cream, red and drak red) and disease severity. The results showed that there was no significant difference between color groups at Sari Station (where low infection of the disease occurred), but in Gorgan Station (under high infection), genotypes wiht dark red, red and white white seed colors, were more resistant than those with cream and white colors. These results can be helpful in screening wheat germplasm for resistance to FHB.
