(1) IL = Recombinant Inbred Lines, BAP = Bioenergy Association Panel, SAP = Sorghum Association Panel (2). Uniformity Trial = same lines planted in strips across field (3) In season 9 a second field ‘North’ was added, and separate trials were conducted
Three hundred thirty one lines were planted in Season 1.
Under scanner system
| Experiment | Reps | Treatments | Experimental design |
|---|---|---|---|
| BAP | 3 | 30 lines (12 PS, 12 sweet, 6 grain) | RCB with sorghum types nested in groups |
| Night illumination | 3 | 5 illumination levels x 2 PS lines (with check line separating illumination levels) | RCB |
| Row # | 3 | 6 adjacent plot scenarios: 3 lines (forage, sweet, PS) x 2 sides (east or west) | RCB but not balanced with all treatments in all reps |
| Biomass | 3 | 5 sampling times x 3 lines (forage, sweet, PS) | RCB with sampling time as a repeated measure |
| Density | 3 | 3 densities (5, 15, 30 cm) x 3 lines (forage, sweet, PS) | RCB |
| RILs | 3 | 130 RILs plus 10 repeats of a single line/rep | Incomplete Block (row-column alpha lattice design) |
| Uniformity | 17 | 2 lines (forage, PS) | None - Same line planted in single range |
