List of phenotypic traits with description, abbreviations, and measured units.
| Trait (unit) | Trait description | Abbrev. |
|---|---|---|
| Total biomass (g) | Aboveground and underground biomass determination. Shoots and roots were dried at 60°C for 72 h before weight determination. | TB |
| Root biomass (g) | Underground biomass determination. The root dry mass was obtained using the same drying procedure as that used for the determination of the total biomass. | RB |
| Root depth (cm) | Length of the longest root (distance from the crown to the tip of the root) calculated from 10 randomly selected plants. | RD |
| Number of productive tillers | Number of tillers with fertile spikes. | NPT |
| Total number of tillers | Number of tillers with fertile and nonfertile (without grains) spikes. | TNT |
| Plant height (cm) | Average plant height measured from soil surface to the tip of spike (including awns) at the harvest time. Plant height was measured in a random sample of 10 plants. | PH |
| Spike length (cm) | Length of spike from 10 randomly selected spikes in a plot (without awns). | LSp |
| Number of grains per spike | Number of grains collected from 10 randomly selected spikes in a plot. | GNSp |
| Weight of grains per spike (g) | Average weight of grains per spike, calculated from 10 randomly selected spikes in a plot. | GWSp |
| Weight of grains per plant (g) | Average weight of grains collected from one plant, calculated as average of measurements of grain weight for 10 plants. | GWp |
| Thousand-grain weight (g) | For the measurement of 1000-grain weight, 1000 seeds were taken randomly from each genotype and grain weight were measured. | TGW |
