Table 1 Estimates of additive genetic variance \( \left({\sigma}_a^2\right) \), residual variance \( \left({\sigma}_e^2\right) \), phenotypic variance \( \left({\sigma}_p^2\right) \) and heritability (h2) for resistance to A. hydrophila in pacu (P. mesopotamicus), measured as test survival (TS) and time of death (TD). Standard error in parenthesis
Variance components | TS | TD |
|---|---|---|
\( {\sigma}_a^2 \) | 0.25 (0.14) | 0.82 × 106 (0.42 × 106) |
\( {\sigma}_e^2 \) | 1 | 0.15 × 107 (0.26 × 106) |
\( {\sigma}_p^2 \) | 1.25 (0.14) | 0.23 × 107 (0.25 × 106) |
h2 | 0.20 (0.09) | 0.35 (0.15) |
