摘　　要：本文对我国杂交水稻自三系配套以来，先后２２年根据全国南方稻区籼型杂交水稻区试实施结果，进行了一次系统、全面的总结，不仅评价了我国南方稻区早、中、晚稻不同熟期，不同发展阶段当选的最佳推广组合的产量及主要经济性状水平。更重要的是提出了近期全国各育种单位选出的一批产量、株型有重大提高和改进的新组合，及其产量与经济性状表现，反映了我国杂交水稻研究的最新进展，无疑对我国杂交水稻的扩大推广应用及“超高产”育种有重要的指导意义。同时，试验资料具有系统、完整亦是我国杂交水稻研究发展的极宝贵财富，对杂种优势理论研究有极丰富的价值。The paper made a systematic summary on Regional Yield Trial result of indica hybrid rice in southern parts of China from 1976 to 1997 and gave an evaluation on the yield potentials and major economic characters of the best combinations with different growth durations adopted in different seasons and developing stages. Meanwhile, It pointed out that a lot of new combinations developed lately by rice research institutes in china had great improvement in yield potential and plant type and presented the latest advancement in the field of research and utilization of rice heterosis in china. The summary is of great importance to developing hybrid rice with super-high yield potential and speeding up hybrid rice utilizations and extension at a larger scale. Furthermore, the systematic data collected in the past 22 years is also a treasure which will guide the research of rice heterosis theories and guarantee the further development of hybrid rice at home and abroad.
