Abstract:
Based on the data from the National Rice Data Center, this study systematically collated glutinous rice varieties approved in Jiangxi Province from 2006 to 2025, and analyzed their traits including variety type, yield, stress resistance and quality. The results showed that 22 glutinous rice varieties were approved, including 18 indica conventional glutinous rice varieties accounting for 81.8% and 9 high-quality glutinous rice varieties accounting for 40.9%. The yield of these varieties mainly ranged from 450.0 kg to 500.0 kg per 667 square meters. Early-season glutinous rice varieties generally possessed more effective panicles, fewer total grains per panicle, high seed-setting rate and heavy 1000-grain weight, while medium and late-season glutinous rice varieties were characterized by fewer effective panicles, more total grains per panicle, high seed-setting rate and heavy 1000-grain weight. Glutinous rice varieties approved from 2006 to 2023 had generally poor resistance to rice blast, whereas those released from 2024 to 2025 exhibited significantly improved blast resistance. Varieties approved from 2021 to 2025 achieved remarkable improvement in head rice rate, accompanied by decreased gel consistency and amylose content. According to the development demands of the local glutinous rice industry, this paper proposes key breeding directions, such as enhancing the exploration of germplasm resources, promoting hybrid glutinous rice breeding, and improving resistance and quality, which can provide references for the breeding of new glutinous rice varieties in Jiangxi.
