Table 2
List of quantitative traits.
| Growth trait/yield trait | Denotation | Method of evaluation |
| Plant height | PH (cm) | The average height from the base to the tip of last leaf (flag leaf) | Flag leaf length to width ratio | FLWR (cm) | Divide the flag leaf length by width | Number of tillers per hill | NT (number) | Count the number of tillers per hill | Days to flowering | DF (days) | Count the number of days from seeding to flowering | Days to maturity | DM (days) | Count the number of days from seeding to maturity | Number of panicles per hill | NP/H (number) | Count the number of panicles per hill | Panicle length | PL (cm) | Measure the length from the node below the lowest branch on the panicle to the top of first superior spikelet | Total number of grain per panicle | TNG/P (number) | Count the number of spikelets per panicle | Hundred grain weight | 100 GW (g) | Weigh any 100 filled grains | Total grain weight per hill | TGW/H (g) | Weigh total grains produced per hill | Seed length | SL (cm) | Measure the length of the seeds using microscopic picture and Leica application suit software | Seed length to width ratio | SLWR (cm) | Divide the seed length by width | Yield in t/ha | Y/ha (ton) | Number of tillers per square meter × average total grains per tillers divided by 100 |
