There were no significant differences in spike number between E24-3-1-6-2-1 and line 7182, but the highly significant increase in spike number was found for addition line 24-6-3-1 ( p < 0.05), compared with 7182 and translocation lines, suggesting that 24-6-3-1 resembled the female parent P. huashanica and tillered profusely ( Table 1 ).
