Other claims from this paper (13)
- Observation The v gene accelerated rice heading time.
- Observation T65, ER, and LR had the reported distinct genotypes.
- Observation ER carried Pi-zt closely linked to Se-1e on chromosome 6.
- Observation E1, E2, E3, and Se-1u were photoperiod sensitivity genes.
- Observation ef-1 substantially extended the basic vegetative growth period.
- Observation The F2 had no distinct transgressive segregants.
- Mechanism The authors infer v is identical to Se-1e.
- Observation T65 had a longer basic vegetative growth period than the tester lines.
- Observation T65 and ER critical day lengths exceeded 16 h.
- Observation LR critical day length was 14–15 h and shorter than that of T65 and ER.
- Observation T65 and ER showed a small retarding effect under super optimum photoperiod compared with LR and did not differ from one another.
- Mechanism The authors attribute T65 low photoperiod sensitivity to v.
- Mechanism The authors attribute the long T65 basic vegetative growth period to ef-1.
