摘要：
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 the genes for the lower stem promote sensitivity to FHB by pleiotropy. The aim of this study was to determine possible correlations between AUDPC for types of resistance to FHB and plant height of wheat genotypes. Spearman correlation coefficient demonstrated 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 between the height of genotypes and AUDPC for Type III resistance (r = -0.18) was not statistically significant.
