查询词典 epistatic

Based on the proposed genetic design, the maize inbreed lines JB and Y53, which are the parental lines of maize hybrid suyu 16 with strong heterosis, were used to create the mixed mapping population with two different cytoplasm backgrounds. The proposed method for mapping cytonuclear epistatic QTL were used to identify the cytonuclear QTL underlying maize agricultural and yield traits.

分析了各种遗传因素在株高和穗位高遗传基础中的相对作用大小，指出了加性、显性和上位性是玉米株高和穗位高的重要遗传基础。

As for digenic interaction, 18 pairs of epistatic loci with R2≥5% were resolved with a mean R2 of 6.9%, ranging from 5.1% to 11.8%, which was slightly larger than that of the main-effect QTLs identified for the traits. The majority of the main-effect and epistatic loci detected for seedling vigor related traits were clustered in a few chromosome regions.

种子活力相关性状的大多数主效应和互作QTLs成串分布于少数几个染色体区段（chromosome regions， CRs），并且成串分布在同一染色体区段的QTLs效应的方向总是一致，该结果与这些性状在表型上的正相关相一致。

As for digenic interaction, 18 pairs of epistatic loci with R2 ≥5 were resolved with a mean R2 of 6.9 ,ranging from 5.1 to 11.8 ,which was slightly larger than that of the main-effect QTL identified for the traits.The majority of the main-effect and epistatic loci detected for seedling vigor related traits were clustered in a few chromo-some regions.

种子活力相关性状的大多数主效应和互作QTL成串分布于少数几个染色体区段(Chromosome Regions，CRs)，并且成串分布在同一染色体区段的QTL效应的方向总是一致，该结果与这些性状在表型上的正相关相一致。

The methods proposed by Wang et al (1999) could analyze additive effects, additive by additive epistatic effects and their interaction with environments, but could not estimate dominance effects and epistatic effects related to dominance.

Wang等(1999)的方法能够分析加性效应、加加上位性效应及其与环境的互作效应，但无法估计显性以及与显性有关的上位性效应。

The method can unbiasedly estimate positions and effects of cytonuclear epistatic QTL as well as simultaneously detect the important epistatic interaction between QTL and inherited cytoplasmic genomes.

该方法既可无偏估计核质互作QTL在核基因组中的位置与效应，又可对有关QTL与细胞质遗传物质间的重要互作效应作出测验和估计。

The experimental results showed that all characters accorded with the addi tiv e-dominant-epistatic model, the additive gene effect and dominant gene effect pl ayed an important role in most characters of 6 crosses, epistatic gene effects w ere significant in all crosses for the 6 investigated traits, additive generic g ene-effects were more important on the spikelets per panicle and spike lets density than its non-additive generic gene-effects (［h］+［j］+［l］), b ut the l atter were relatively more crucial on the days to heading and panicle length in the two tested lines.

结果表明：六个性状都符合加性-显性-上位性模型，加性效应对两个多小穗小麦品系各性状的遗传有重要作用，部分性状存在显著的显性效应，不同类型上位性效应对各性状有不同程度的影响；各性状之间各类基因效应平方和百分比差异较大，不同类型上位性基因效应平方和百分比大小因被测系、组合而异。
