由８个亲本组成的双列杂交试验，分析了穗长、穗粗、穗行数、百粒重、单株籽粒产量的基因效应。Ｗｒ／Ｖｒ和Ｄ、Ｈ、（Ｈ／Ｄ）分析表明，除单株产量存在显著的上位性，不符合加性—显性模型外，其余４个性状均符合加性—显性模型。穗粗、穗行数以加性效应为主，穗长、百粒重、单株产量显性效应和上位性起主要作用；穗粗隐性基因为增效，显性基因为减效，其余性状均为显性基因增效，隐性基因减效；穗长、穗粗、穗行数的狭义遗传力较高为５０．８％～８７．９％，百粒重、单株产量较低为２１％左右；平均杂种优势效应按强弱顺序是单株产量＞百粒重＞穗长＞穗粗＞穗行数。
A double-row hybridization experiment was made by 8 parents to analyze the gene effect of ear length, ear diameter, ear number, 100-grain weight and grain yield per plant. Wr / Vr and D, H and (H / D) analysis showed that all the four traits accorded with the additive-dominance model except that there was significant epistasis per plant and did not fit the additive-dominance model. Spike thick, the number of ear rows to the additive effect, spike length, 100 grain weight, yield per unit plant yield epistasis and epistasis play a major role; spike coarse recessive gene for efficiency, the dominant gene for the reduction, the rest Traits were dominant gene efficiency, recessive gene reduction; ear length, ear diameter, ear number narrow sense of the hereditary 50.8% to 87.9%, 100-weight, lower yield per plant The average heterosis was in the order of strength and weakness, which was per plant yield> 100 kernel weight> panicle length> ear diameter> ear number.
