研究采用一套构建好的重组自交恢复系和不育系辽99A组配所得的杂交粳稻为试材，对此杂交粳稻的产量和产量构成要素性状进行测定分析，并分析了产量与各构成要素之间的关系。研究表明对于整个杂交粳稻群体来说各产量构成因素间的矛盾并不明显。杂交粳稻的产量在一定范围内与每穴有效穗数、穗粒数和结实率呈显著正相关，表现为杂交粳稻的产量随着有效穗数的增加产量迅速提高，充足的有效穗数是高产的必要因素。当穗粒数逐步提高时，产量也随着其提高而增加。同时，结实率的增加也能显著的提高产量。而千粒重的表现则与产量没有必然的联系。通过研究杂交粳稻产量构成要素与主要农艺性状之间的关系，为杂交粳稻育种提供一定的理论依据。

For analysis on hybrid japonica rice yield and yield components traits, a series of recombinant inbred restorer lines (RILLs) and the hybrid combinations crossing between the RILs and Liao99A CMS line were used. The results showed that the contradiction is not obvious between the yield and yield components. The concentrations among yield and yield components were positively correlated at 0.05 levels. The yield of japonica hybrid rice rapidly increased with the increase of effective panicle number. For high yield, the plenty of panicle number is a necessary factor. The yield of japonica hybrid rice also increased with the increasing of grain number per panicle and seed set rate, but the correlation coefficient of 1000 grain weight and yield didn't reached significant level. Through the study on relationship between hybrid japonica rice yield components and the yield components traits, attempting to provide certain theoretical basis for hybrid japonica rice breeding.
