S. No | Traits name | Abbreviations | Description |
1 | Seedling vigor | SV | Visual observation of the seedling in 1 - 5 scale where 1 poor and 5 highly vigor |
2 | Days to 50% flowering | DFL | The date when 50 percent of the plants produced flowers was recorded and converted in number of days from date of planting up to date of heading |
3 | Plant height | PLHT | Height of the plant from the base of the plant to the tip of the panicle in cm at maturity |
4 | Total number of leaves | TNOL | Number of leaves on the main plant stem |
5 | Leaf area | LA | Measurement of leaves (cm2) using LI 3000 C Portable area meter from 5 randomly selected plants in each replication during early morning hours when leaves were fully turgid |
6 | Stay green | StG | Stay-green scores at maturity based on visual ratings [18] using 1 to 5 scale (1 ≤ 10% leaves stay green and 5 => 75% leaves stay green and most desirable) |
7 | Peduncle exsertion | PEX | The average length of the node between the flag leaf and the base of the panicle measured in cm from 5 randomly selected plants at maturity then ranked by their values |
8 | Panicle length | PL | Panicle length measurement (cm) from the base of the panicle to the tip from five randomly selected plants per plot at maturity |
9 | Panicle width | PW | Panicle width measurement in the widest diameter of the panicle on five randomly selected plants per plot at maturity |
10 | Days to maturity | DM | The date when 90 percent of the plants are physiologically mature counting in days taken from planting up to physiological maturity |
11 | Over all plant agronomic score | OAS | Over all plant agronomic scores (5 = most desirable and 1= least desirable) [19] |
12 | Grain weight | GW | Total grain weight per plot (kg) after threshing then converted into tons per hectare |
13 | Biomass | BM | The total weight of the plants in the two middle rows (Kg), 15 plants/row then averaged value |
14 | Harvest index | HI | The ratio of grain weight to the total biomass (%) computed from the two middle rows then taken average value |
