Effect of variety on yield-related traits under irrigated and drought condition.
| Irrigated | Drought | |||
|---|---|---|---|---|
| ‘4610’ | Rondo | ‘4610’ | Rondo | |
| (1) Filled grain number per panicle | 68.2* | 80.1 | 69.5* | 58.9 |
| (2) Unfilled grain number per panicle | 21.2* | 27.5 | 31.2 | 30.5 |
| (3) Spikelet fertility (%) | 76.9 | 74.3 | 69.5* | 65.9 |
| (4) Filled grain weight (g) per plot | 77.3 | 63.8 | 55.3 | 43.7 |
| (5) Unfilled grain weight (g) per plot | 5.7 | 6.9 | 4.1 | 4.6 |
| (6) Total grain weight (g) per plot | 83.0 | 70.7 | 59.5 | 48.3 |
| (7) Plant dry weight (g) | 200.76 | 163.9 | 126.6 | 117.3 |
| (8) Hundred-seed weight (g) | 2.9** | 2.7 | 2.9** | 2.6 |
| (9) Panicle length (cm) | 19.5** | 21.6 | 19.5 | 19.5 |
| (10) Yield (kg ha–1) | 10,666 | 10,351 | 9,850.04 | 9,035.18 |
Traits with ‘*’ and ‘**’ indicates that the difference between the two cultivars under the same condition was significant by P < 0.05 and P < 0.001, respectively.
