It had been shown that hybrids have significant midparent heterosis and dominant effect, hybrid growth response to submergence was controlled by the parents, but the effects of restorer lines were stronger than CMS lines, e.

对生产上主栽的三系杂交组合及其与亲本耐淹涝能力的关系进行了比较研究，确定杂交稻的耐淹涝能力的平均优势明显，显性效应为主。

To investigate the effect of hereditary factor on the stature of "She" nationality \ Methods\ In a population of 393 youths aged 18～25 years from Muyang village Fu'an County, the heritability of stature was estimated by midparent child regression.

目的 探讨遗传因素对畲族人群身高的影响。方法调查福安市穆阳乡畲族 18～ 2 5岁青年 393名，用直线回归方法以亲代与子代身高之间的回归系数估计子代身高的遗传率。

Accordingly we start from the definition of heterosisH=F1-MP,where H is heterosis, F1 is the first generation offspring, MP is the mean of the parents or midparent, and from the use of a binomial random variable and its extention to the multinomial case derive the basic relations of heterosis with its components.

另一在原文中未加说明的原因是，用配合力概念需要无穷多个品系才能和遗传力的结果相比较，仅此一点就把配合力的作用排斥掉了。文中的主题是杂种优势老大难题可以用笛卡尔的推理方法来解决。

The equations of heterosis areV(subscript F1)=(l/2)Na^2+(l/4)Nd^2+Vsubscript I(F1additive dominance F1 epistasisV=(1/2)Na^2+(l/2)V1,additive parental epistasisV=(1/4)Nd^2+Vsubscript I(F1+(1/2)Vl,dominance F1 epistasis parental epistasis.where N is number of genes controlling a trait,α=P(subscript i-P/2, d is deviation from midparent, while the variance components are all indicated by their names under the repective terms.

由一个二项分布随机变数及其推广至多项分布推导出杂种优势的公式：V(下标 F1)=Na^2/2+Nd^2/4+V下标(F1加性显性 F1上位V＝Na^2/2+V/2加性亲代上位V＝Nd^2/4+V下标(F1+V/2显性 F1上位亲代上位在此N=控制性状的基因数，α=p(下标 i-P/2， d=离中亲的偏差，而各方差则如方程底部所列。
