摘要:

为了探讨水稻农艺性状和品质性状对血糖生成指数(GI)的影响,并筛选低GI育种潜力的理想亲本,本研究以13个水稻品种为试材,通过田间试验与实验室测定,分析农艺性状、品质性状、淀粉特性及其与GI的关联。结果表明:直链淀粉含量与基本苗密度呈潜在正相关(r=0.524,P=0.066),抗性淀粉含量与糙米率呈显著正相关(r=0.568,P<0.05)。综合农艺性状、淀粉特性及品质指标,筛选出‘中早88’和‘早籼617’两个品种:‘中早88’抗性淀粉含量最高(7.94%),直链淀粉含量较高(24.91%),糙米率高;‘早籼617’直链淀粉含量次高(31.03%)且稳定性好,产量高(10.4 kg/13.3 m²)且稳定。基于上述研究,成功筛选出2个低GI候选亲本,为当地低GI水稻育种奠定了基础。

Abstract:

To explore the influence of agronomic and quality traits on the glycemic index (GI) of rice and to screen ideal parents with low-GI breeding potential, field experiments and laboratory determinations were conducted to analyze the differences in rice agronomic, quality traits and starch characteristics and their correlations with GI using thirteen rice varieties as experimental materials. The results showed that potential positive correlation was observed between amylose content and basic seedling density (r=0.524, P=0.066), and resistant starch content was significantly positively correlated with brown rice rate (r=0.568, P<0.05). Based on agronomic traits, starch characteristics and quality indicators, two varieties, ‘Zhongzao 88’ and ‘Zaoxian 617’ were selected. ‘Zhongzao 88’ had the highest resistant starch content (7.94%), a relatively high amylose content (24.91%), and a high brown rice rate; ‘Zaoxian 617’ had the second highest amylose content (31.03%) and good stability, with a high and stable yield (10.4 kg/13.3 m²). Based on the above research, two low-GI candidate parent lines were successfully screened, laying a foundation for local low-GI rice breeding.
