Table 1. Germination related traits of B73, Mo17 and Syn4 population and their heritabilities under low and optimal temperature conditions.
| Traitsa | Parentb | Syn4 population | ||||
|---|---|---|---|---|---|---|
| B73 | Mo17 | Range | Mean | CV (%)c | H2 (%)d | |
| OTGR (%) | 97.8±3.8A | 60.0±6.7B | 4.4–100.0 | 81.7 | 25.9 | 88.5 |
| LTGR (%) | 95.6±3.8A | 35.6±3.8B | 0.0–100.0 | 52.6 | 58.1 | 88.3 |
| LTPRL (mm) | 26.7±1.0A | 8.1±2.1B | 0.2–36.0 | 11.3 | 54.7 | 94.5 |
aOTGR, LTGR, LTPRL represents optimum-temperature germination rate, low-temperature germination rate, low-temperature primary root length, respectively.
bMeans with the standard deviation of the parental lines that followed by the different upper-case letter significantly differ by Student's t test at 1% level of significance, respectively.
cCV: coefficient of variation.
dH2: heritability.
