摘　　要：对5个杂交粳稻不育系和5个恢复系配组的25个组合的研究表明:粒重对产量影响显著,粒重高的组合产量也较高,呈显著正相关。通径分析表明,粒重对产量的贡献较大;粒重对直链淀粉含量的影响不显著。An experiment of 25 cross combinations between 5 sterile lines of japonica rice and 5 restoring lines was carried out in order to study the effects of grain weight on grain yield and quality of hybrid japonica rice.The result showed that the grain weight had a significant effect on grain yield and was a positive correlation with grain yield.The path analysis also indicated that the grain weight made a quite great contribution to the grain yield.The grain weight had not a significant effect on the amylose content of grain.
