对田间F2群体452株调查，芒色的分离比例白色：有色为109：343，该性状受来自父、母本2对互作基因隐性上位基因控制，χ^2检验结果符合12：4分离比例。

The epistatic interaction was analysised in entire genome and a total of 39 digenetic interaction marker pairs were found which contributed 6. 41%-25. 65% variance to genetic variation. It suggested that epistasis between non-QTL and non-QTL was the primary interaction form in the resistance response.

在全基因组对所有抗性性状进行了上位性分析，一共检测到39个两位点互作标记对，结果表明两位点间的互作主要以非QTL与非QTL互作形式存在，针对不同的性状，上位性作用能够解释6.41％-25.65％的遗传变异。

Regarding to QTL analysis with single locus, segregation distortion would not affect QTL mapping, but regarding to analysis of digenic interactions for epistasis, the fewer distortion markers and larger size population would be needed.

对于单位点的QTL分析而言，偏分离标记一般不会影响QTL定位的位置和效应；对于两位点的上位性分析而言，则要求较少的偏分离标记和较大的群体。

Regarding to QTL analysis with single locus,segregation distortion woul d not affect QTL mapping,but regarding to analysis of digenic interactions for epistasis,the fewer distortion markers and larger size population would be needed.

对于单位点的QTL分析而言，偏分离标记一般不会影响QTL定位的位置和效应；对于两位点的上位性分析而言，则要求较少的偏分离标记和较大的群体。

The accumulated contributions of main effect QTLs for AC and PC were 35.34%, 37.33% under normal conditions and 53.40%, 58.10% under water stress condition, and the accumulated contribution of digenic epistasis for AC and PC were 66.74%, 57.49% under normal conditions and 48.65%, 36.59% under water stress conditions, respectively.

主效QTL对直链淀粉和蛋白质含量的联合贡献率在非胁迫条件下为35.34%和37.33%，在胁迫条件下分别为53.40%和58.10%；互作位点对直链淀粉和蛋白质含量的联合贡献率在正常水分条件下分别为66.74%和57.49%，在胁迫条件下分别为48.65%和36.59%。

Additive effects were predominant, totally explained 75% of the phenotypic variation and often combined with digenic epistasis. Of 12 main QTLs,9 showed Gaoyou alleles decreasing plant height. Most QTLs with QE effects showed ecologically favourable alleles in diverse regions.

株高受多个QTL影响（12个位点具有加性或兼有环境互作效应，5个位点具有互作效应），以加性效应为主，加性效应总和可解释定位群体表型变异的75%左右，并多兼有上位性效应。12个主效QTL中，9个是&高油&等位基因相对&Sollux&有降低株高的作用，大多数加性×环境互作QTL的有效等位基因具有环境选择特异性。

Stuber et al.(1992) considered the overdominance is the major genetic basis of heterosis in maize; Xiao et al.(1995) suggested the dominance is the major molecular mechanism of heterosis in rice. Subsequently, Yu et al.(1997) and Hua et al.(2003) demonstrated the epistasis made the siginificant contribution to heterosis in rice.

Stuber等认为，超显性是玉米杂种优势形成的主要原因；Xiao等(1995)认为显性作用是水稻杂种优势形成的遗传基础，Yu等(1997)和Hua等(2003)认为上位性在杂种优势形成过程中起重要作用。

The combining action of the additive effect of the genes from both parents and two-loci epistasis-effect may be responsible for the transgressive segregation of tiller angle in rice population.

不同基因的加性效应和双位点的上位性效应的共同作用可能是造成水稻分蘖角度超亲分离的主要原因。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
