DNA methylating inhibitor has been used in the study of epigenesis that caused by DNA methylation of plants.Also,it can be instead of low temperature treatment to induce flowering of plants,make flowering time earlier than usual.Further study and application in the improvement of plants will be continued.

DNA甲基化抑制剂已被用于因DNA甲基化引起的植物表观遗传研究中，同时它可以代替低温促进植物提早开花，并可能在植物性状改良中得到进一步的研究和应用。

However, because of the limitation of technology and the lack of flexible statistical method, epistasis, especially the cytonuclear epistasis was neglected too often in complex trait studies.

然而，由于技术发展的限制和相关统计分析方法的缺乏，上位性，特别是核质互作上位性在复杂性状遗传中的重要性常常被研究人员忽视。

Except for major QTLs, epistasis played an important role in the genetic basis of yield and fiber traits in upland cotton.

除了主效QTL外，上位性是陆地棉产量和纤维品质性状的重要遗传基础。

Furthermore, it was indicated that epistasis was the main genetic dynamics of speciation and adaption and the primary genetic component of heterosis and complex traits.

遗传物质间上位性是物种分化和适应的重要遗传学动力，也是复杂性状和杂种优势形成的重要遗传组分。

These near-isogenic lines were precious genetic materials for exactly mapping QTL and studying the effects of QTL and epistasis.

这些近等基因系可进一步用来精确定位性状的QTL位点和分离QTL位点及互作位点的遗传效应。

By the method of generation means, the heredity of fiber quality traits were mostly additive, as well as epistasis.

经模型适合性检验，纤维长度和纤维伸长率两个纤维品质性状符合加性—显性—上位性遗传模型。

The error variance in genetic analysis of poultry continuous traits was estimated by the method of the linear model.

By using a DH population derived from a rice indica/japonica cross, genetic analyses of floral characters, such as percentage of exserted stigmas, stigma length, stigma width, style length, anther length, anther width, spikelet length, spikelet width, length-width ratio of spikelet, and panicle exsertion degree, were conducted in the present study.

利用一个水稻籼粳交（窄叶青 8 号/京系 17 ）来源的 DH 群体对水稻柱头外露率、花柱长、柱头长、柱头宽、花药长、花药宽、颖花长、颖花宽和颖花长宽比 9 个花器性状和穗抽出度进行遗传分析。

In order to identify the mechanism of melanic mutant of S. exigua, genetic regulation on pupae body color, puparial exuviae, phenoloxidase activity, dopamine andβ-alanine of SEW and SEM were investigated.

本文以SEW和SEM为材料，分别从蛹黑色性状的遗传规律、多酚氧化酶活力、电镜分析、高效液相分析、多巴胺和β-丙氨酸的微量注射及饲喂诱变几个方面进行了研究，以期找出甜菜夜蛾黑化的机理。
