Least significant difference (LSD) was used in the multiple comparison tests for each trait. Different letters between two samples indicate significant differences (p value < 0.01). H3, T452, JG, JD and DAF indicate Huaduo3, Huajingxian74-4x, plants with high fertility, plants with low fertility and days after flowering, respectively.
