Table 1.
Concentrations of total carotenoids in different generation and germplasm backgrounds of GR2E rice.
| Breeding Generation | Total Carotenoids (µg/g FWT)† | |||
|---|---|---|---|---|
| Kaybonnet | PSB Rc82 | IR64 | BRRI dhan 29 | |
| T(n) | 30.50 ± 2.49 | — | — | — |
| BC3F5 | — | 12.84 ± 3.32 | 20.11 ± 8.71 | NDa |
| BC4F3 | — | 9.09 ± 2.26 | 19.40 ± 2.00 | 24.50 ± 2.85 |
| BC5F3 | — | 14.12 ± 0.11 | 13.23 ± 1.16 | 29.33 ± 3.14 |
†Values shown are mean values ± SD (standard deviation) determined spectrophotometrically for total carotenoids in grain samples after one day of storage at 16 °C. All concentrations are on a fresh weight (FWT) basis, not corrected for moisture content.
aND = Not determined. Due to poor quality of remnant seed from the BC3F5 generation of BRRI dhan 29 containing GR2E, there was no seed germination and plants could not be produced for grain sampling.
