Pollen and Seed Viability in the rpe1 Mutant at the Mature Stage
| Wild Type (Fujiminori) | rpe1 | Wild Type (T65) | Slr1-d3 | |
|---|---|---|---|---|
| Viable pollen (%)a | 91.61 ± 7.04 | 88.57 ± 6.52 | 90.5 ± 0.84 | 29.20 ± 4.51* |
| Number of pollen grains | 4317 ± 257 | 4300 ± 427 | 4875 ± 730 | 4592 ± 474 |
| Seed viability (%)b | 92.30 ± 0.97 | 42.39 ± 2.38* | 82.0 ± 1.27 | 56.0 ± 3.03* |
a
Pollen grains staining black with I2-KI solution were judged as viable, and those staining yellow or light red were considered sterile. The percentage of viable pollen was calculated relative to the total pollen counted. *Significantly different from the wild type (P < 0.01).
b
Seed viability represents the percentage of spikelet number that set seed per total number.
