由于数量性状表型变异的连续性，无法用传统的孟德尔方法对单个数量性状位点（ＱＴＬ）进行分离和定位。８０年代初发现的ＤＮＡ分子标记已被广泛应用于ＱＴＬ的分离、定位及遗传效应估计，即ＱＴＬ作图。统计学分析是实现ＱＴＬ作图的一个重要环节。本文对８０年代以来ＱＴＬ作图统计方法的主要发展进行了简要综述。

Selenium (Se) in the environment and food chains was greatlyrelated to animal deve- lopment and human health. Soils are the mainsources of Se in ecosystem. Numerous studies have been carried toinvestigate relationships between Se and S in soils. Xu (1992)reported that Se and S had similar chemical and physical propertiesso some factors influencing the uptake and toxicity of Se areattributed to the interaction of Se with S. Therefore, in order tocontrol and improve soil Se conditions, i.e., to reduce the Secontents of crops in Se-toxic soils or to increase the crop Secontents in Se-deficient soils by agricultural methods, S should beconsidered as an important factor.

啤酒大麦植株中的钼含量是种子＞叶＞根＞茎，除茎外均与施磷量呈显著曲线相关；而铁的含量是根＞叶＞茎＞籽，只有根及叶中的铁含量与施磷量呈显著曲线相关，但根中的铁含量随施磷量增加而增加。施大量磷肥会降低植株中的含铁量，铁主要集中在根部，当施P2O54.8g／盆时，叶中的含铁量比根低8．61倍，且叶中的P／Fe增大，达63—75倍，故呈现缺铁症。施磷（P2O5）2．4.／盆时，其体内各器官钼、铁含量最高，植株成熟时，钼、铁积累量分别为14.9μg／盆、3218μg／盆。种子中钼积累量最多，占总量的62．3％，而铁仅占总量的10．2％。施适量磷肥，能明显提高啤酒大麦的钼、铁含量及其产量和品质，增加千粒重、淀粉含量及降低粗蛋白质含量等。

Dear Editor,Utilization of heterosis is fundamental to modern agricultural improvement and contributes significantly to food security and agricultural development(Ouyang et al.,2022).However,heterosis of F,hybrids cannot be stably ***,or asexual reproduction through seeds,offers the potential for the fixation of heterosis in F,hybrids and the formation of clonal offspring,which could have considerable implications for plant breeding and agriculture(Schmidt,2020).But naturally occurring apomixis has never been found in major ***,synthetic apomixis has been successfully generated by inducing incomplete meiotic development combined with parthenogenesis development to produce cloned rice(Oryza sativa)seeds(Khanday et al.,2019;Wang et al.,2019;Vernet et al.,2022;Wei et al.,2023).
