Means, variance components, and heritability for BLUPs of five traits under well‐watered and water‐stressed treatment and their drought response
| Trait a | Well‐watered (WW) | Water‐stressed (WS) | Response (WW‐WS) | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Mean | SD | G | GxY | H 2 | Mean | SD | G | GxY | H 2 | Mean | SD | G | H 2 | |

Note: SD: standard deviation; G: Genotype; GxY: Genotype‐by‐Year interaction; H 2: Broad‐sense heritability. Significance at p < .05, .01, and .001 for two‐way ANOVA is noted with *, **, and ***, respectively. G and GxY terms without asterix did not pass the significance threshold.

Traits: PH: Plant height (cm); FB: Forage biomass (g); DF: Days to flowering (days); GW: Grain weight per panicle (g).
