The Bangkok genotype had higher filled grain weight per panicle than the other genotypes under high-temperature stress.
Verbatim
t0“Local Upland Rice (Oryza sativa L.)”
e0“The Bangkok genotype has a quantity of pollen germinated of 61.21-44.64%, spikelet fertility in each panicle of 74.91-215.52 grains andweight of filled grain in each panicle of 1.43-4.88 g higher as well as a decrease in amylose and an increase in protein lower than the other three genotypes at high-temperature stress at various stage stages”

Other claims from this paper (12)
- Intervention effect High temperature during the generative stage significantly reduced pollen germination in all genotypes.
- Intervention effect High temperature during the vegetative-generative stage significantly reduced pollen germination in all genotypes.
- Intervention effect Generative-stage high temperature seriously affected panicle length, spikelets per panicle and spikelet fertility compared with stress at the other stages.
- Intervention effect Generative-stage high temperature seriously affected filled grain weight per panicle and 1000-grain weight compared with stress at other stages.
- Intervention effect Generative-stage high temperature reduced amylose relative to stress at other stages.
- Intervention effect Vegetative-stage high temperature significantly increased panicle length, spikelet number and spikelet fertility.
- Intervention effect Vegetative-stage high temperature significantly increased filled grain weight per panicle and 1000-grain weight.
- Observation The Bangkok genotype had higher pollen germination than the other genotypes under high-temperature stress.
- Observation The Bangkok genotype had higher spikelet fertility than the other genotypes under high-temperature stress.
- Observation The Bangkok genotype showed a lower amylose decrease than the other genotypes under high-temperature stress.
- Observation The Bangkok genotype showed a lower protein increase than the other genotypes under high-temperature stress.
- Recommendation The authors identify the Bengkok genotype as a potential source of heat tolerance for breeding.
