| 摘 要： | 以20份产量差异显著的杂交粳稻组合为试材,分析高产杂交粳稻的产量结构和穗部性状特征.结果表明:高产的杂交粳稻组合产量结构优势主要表现在有效穗数多、结实率高、生物产量大;穗部性状优势主要表现在一次枝梗粒数多上.穗数与二次枝梗结实率呈显著正相关;穗粒数与一次枝梗粒数呈显著正相关;结实率与二次枝梗数、二次枝梗粒数呈显著正相关...

| Abstract: | To analyze the yield component and panicle characters of high-yield japonica hybrid rice,20 hybrid japonica rice cultivars with different yield levels were used to study high-yield and its relationship with panicle characteristics and yield component.The results showed that it was advantageous to increase yield by increasing number of panicle,seed setting rate and superiority of biomass,and to improve the panicle characters by increasing grains number at primary branch.There were significant positive correl... |
