Table 2 Statistical determination of difference in the root length in Q21861 and rpr9

From: Characterization of genes required for both Rpg1 and rpg4-mediated wheat stem rust resistance in barley

Group rpr9 Q21861
N (Sample size) 14 14
Mean root length 16.5 25.64
SD 1.65 1.82
SEM 0.44 .49
  1. An unpaired t-test was used to determine if the difference of root length (in mm) at the 4th day of germination was significantly different between the rpr9 mutant and wildtype Q21861. The difference between the root lengths were statistically significant (two tailed P value = 0.0065). SD- Standard deviation, SEM - Standard error of mean
