Other claims from this paper (13)
- Observation Among 334 early-season rice varieties released from 2000 to 2022, varieties containing 18-20% amylose content were the most prevalent (23.6%).
- Observation Low-amylose varieties collectively accounted for 46.4% of the 334 early-season rice varieties.
- Association Amylose content was significantly positively correlated with chalky kernel rate and chalkiness degree across the 334 varieties.
- Association Amylose content showed no correlation with yield across the 334 varieties.
- Intervention effect In field experiments, low-amylose and medium-high-amylose varieties achieved comparable yields through compensatory adjustments.
- Intervention effect Low-amylose varieties had 12.8-13.9% more panicles per m2 than the comparison varieties.
- Intervention effect Low-amylose varieties had 3.6-7.3% lower 1000-grain weight than the comparison varieties.
- Intervention effect Low-amylose varieties had 70.8-73.5% lower chalky kernel rate (CKR).
- Intervention effect Low-amylose varieties had 54.0-62.1% lower chalkiness degree (CKD).
- Intervention effect Low-amylose varieties had a smaller maximum grain-filling rate and maximum amylose accumulation rate.
- Intervention effect Low-amylose varieties had a smaller mean grain-filling rate and mean amylose accumulation rate.
- Intervention effect Low-amylose varieties had longer active grain-filling and amylose accumulation periods.
- Intervention effect Low-amylose varieties had higher activities of soluble starch synthase during grain-filling stages.
