按不完全双列杂交方式组配了12个栽培稻与普通野稻种间杂交组合，定量分析其杂种优势和利用加性-显性模型对11项农艺性状进行遗传分析。结果表明：12个栽野交组合的平均杂种优势为-0.608~3.031，穗数和籽粒长宽比表现强优势是其主要特征。栽野交的穗数、籽粒长宽比、结实率和抽穗期的优势显著高于籼粳交。各性状具有较高的广义遗传力(0.50~0.92)；狭义遗传力为0.24~0.84，籽粒长宽比和抽穗期的狭义遗传力较高，其它性状中等偏低。各项农艺性状间具有显著或极显著水平的表型相关和遗传相关，可作为育种间接选择时的有效参考指标。

12 combinations were made between cultivated rice (Oryza sativa) and common wild rice (Oryza rufipogon) according to the incomplete diallel mating design. Quantitative analysis of the heterosis and genetic analysis of 11 agronomic characters with additive-dominative model were made for theses combinations. The results showed that the average heterosis for 12 combinations was –0.608~3.301. Strong heterosis for the panicles per plant and length/width ratio of spikelet was their main characteristic. Panicles per plant, length/width ratio of spikelet, seed setting rate and heading date for the combinations between cultivated rice and common wild rice showed stronger heterosis markedly than those for hybridizations between indica rice and japonica rice. The general heretability in the broad sense were 0.50~0.92, rather high for 11 characters. The general heretability in the narrow sense were 0.24~0.82, with length/width ration of spikelet and heading date showing rather higher general heretability in the narrow sense while the other characters were low. There existed significant or very significant phenotypic correlations and genetic correlations among 11 characters. These relationships can be the efficient reference index while making indirect selections in breeding.
