选用４个汕型不育系和７个恢复系，按不完全双列杂交配成２８个组合，用相关分析、通径分析和配合力分析法对主要农艺性状进行分析。结果表明：对单株粒重直接作用大的性状依次为每穗实粒数、单株穗数、千粒重；播始历期对单株粒重的直接作用和其它性状，通过该性状的间接作用很小，说明在早稻生育期范围内，实现高产是可能的；珍汕９７Ａ、ＥＴ２１８０、ＥＴ３０４２的单株粒重和每穗实粒数的一般配合力效应最高，易获得产量和实粒数高的组合；早红突Ａ单株穗数的一般配合力效应和特殊配合力方差均高，所配组合易获多穗；就单株粒重来看，杂交组合珍汕９７Ａ×ＥＴ１９４４组合的特殊配合力效应和Ｖ２０Ａ×ＥＴ３０４２组合的平均数均最高。
Four Shanyou sterile lines and seven restorer lines were selected and 28 combinations were made by incomplete diallel cross analysis. The main agronomic characters were analyzed by correlation analysis, path analysis and combining ability analysis. The results showed that the direct effect on the grain weight per plant was followed by the number of true grains per panicle, the number of panicle per plant, the value of 1000-grain weight. The direct effect of the initial duration on grain weight per plant and other traits were indirect effects of this trait Is very small, indicating that it is possible to achieve high yield in the range of early rice growth period. The grain yield of Zhenshan 97A, ET2180 and ET3042 had the highest general combining ability and the higher yield and grain number The combination of the early maturing Rhizome A plant spike number of the general combining ability and special combining ability variance are high, the combination of easy to get more spike; grain weight per plant point of view, the combination of hybrid Zhenshan 97A × ET1944 special The combining effect and the combination of V20A × ET3042 average the highest.
