OX (HJ19) and OX (ZH11) represent the overexpressed plants of the Hejiang 19 and Zhonghua 11 genotype, respectively. No, number of plants investigated; HD, heading date. P1 values were obtained by t tests for significant difference in heading date between the positive and negative plants. P2 values were obtained by chi-squared test for segregation of 3:1. T0 plants came from different resistant callus. T1 plants came from one T0 plant.
