Marker-trait association analysis of the F2 population. a Frequency distribution of lesion degree in the F2 population. b Comparison of lesion degree among the three genotypic classes of the Pi21 locus in the F2 population. Data was presented as the means ± SD (standard deviations). −/− represents Kongyu-131-homozygous lines, +/− represents the heterozygote, and +/+ represents GKGH-homozygous lines. **above the bar chart represents a significant difference based on Student’s t-test at p ≤ 0.01
