Impact of wheat height to FHB resistance

The relationship between plant height and resistance to fusarium head blight (FHB) has a genetic basis. It is believed that the genes controlling FHB resistance and those that affect the plant height are associated , or it is pleiotropy where genes for low stem promote higher FHB sensitivity. The aim of this study was to determine correlations between AUDPC for Types of resistance and height properties of wheat genotypes. Spearman correlation coefficient was determined by high negative significance between height of genotypes and AUDPC for total amount of resistance (AUDPC) (r =- 0.77) and between height of genotypes and AUDPC for Type I resistance (r=-0.81). The correlation between height of genotypes and AUDPC for Type II resistance (r=0.14), and the height of genotypes and AUDPC for Type III resistance (r=-0.18) was not statistically significant.
