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 )的方法能夠分析加性效應(yīng)、加加上位性效應(yīng)及共與環(huán)境的互作效應(yīng),但無(wú)法估計(jì)顯性以及與顯性有關(guān)的上位性效應(yīng)。
The results oft - test indicated that few genetic main effects of qtls found were significant , among which additive by additive epistatic effects and additive effects were most significant for qtls controlling heading date , additive effects were most significant for qtls controlling kilo - grain weight T測(cè)驗(yàn)的結(jié)果表明,鑒別出的qtl中,遺傳主效應(yīng)達(dá)到顯著的不多,其中抽穗期的qtl以加加上位性效應(yīng)和加性效應(yīng)最為顯著,千粒重以加性效應(yīng)最為顯著。
Genetic models were constructed for qtl mapping by two - dimensional searching . corresponding analysis methods were also proposed , which could estimate additive effects , dominance effects , epistatic effects of additive by additive , additive by dominance , dominance by additive , dominance by dominance , and could predict their interaction effects with environments 構(gòu)建了可以估汁加性效應(yīng)、顯性效應(yīng)、加加、加顯、顯加、顯顯上位性效應(yīng)以及預(yù)測(cè)這些效應(yīng)與環(huán)境互作效應(yīng)的qtl定位兩維搜索遺傳模型,提出了相應(yīng)的分析方法。
It was shown that in short - season cotton , the seven traits relating to early maturity all presented dominating additive effect while displaying dominance effects , and epistatic effects from sowing to budding , from sowing to flowering and from budding to flowering ; the early maturity traits significantly interacted with the environments 結(jié)果表明:短季棉7個(gè)早熟相關(guān)性狀的遺傳均以加性效應(yīng)為主,同時(shí)存在著顯性效應(yīng),對(duì)于播種現(xiàn)蕾、播種開(kāi)花和現(xiàn)蕾開(kāi)花還存在著上位性效應(yīng);短季棉各早熟性狀的遺傳效應(yīng)與環(huán)境互作顯著。
It emphasizes on development of ct drive of profibus and ge 90 - 30 plc communication software , and draw a conclusion that using site bus can make the relation between plc and drives more close and can expediently exchange huge amount of data between them , therefore make it possible to realize epistatic control 本章重點(diǎn)探索了基于profibus的叮馬動(dòng)器與m90 30plc的通訊軟件的開(kāi)發(fā),由此得出了使用現(xiàn)場(chǎng)總線后可以使得plc與驅(qū)動(dòng)器之間的聯(lián)系更為緊密,可以彼此方便地交換大量數(shù)據(jù),從而使上位監(jiān)控成為可能。
Abstract : in this paper , triple test cross design was used in studing the resistance of soybean to 10 physiological race of cercospora sojina haraby inoculation . results o analysis of gene effects of resistance indicated that additive effect is significant in all the three crosses , dominant effect exsists only in the cross 1 and epistatic effect remains in the cross 2 and cross 3 摘要本實(shí)驗(yàn)利用三點(diǎn)測(cè)交分析的方法,對(duì)3個(gè)組合在人工接種大豆灰斑病菌的條件下的抗性表現(xiàn)進(jìn)行基因效應(yīng)分析,各組合均存在加性,組合1存在顯性,組合2 、 3存在上位性。
Monte carlo simulations were conducted to study the new approaches of qtl mapping , the results indicated that general least squares ( gls ) method , which was widely applied in mixed linear model , could unbiasedly estimate all genetic main effects , including additive effects , dominance effects and epistatic effects of additive by additive , additive by dominance , dominance by additive , dominance by dominance . the interaction effects between genetic main effects and environments could also be predicted unbiasedly by linear unbiased prediction ( lup ) . the heterosis prediction based on qtl effects was also unbiased 對(duì)新提出的qtl分析方法進(jìn)行了montecarlo模擬研究,結(jié)果表明,廣泛應(yīng)用于混合線性模型的廣義最小二乘法( gls )能夠無(wú)偏估計(jì)加性效應(yīng),顯性效應(yīng)以及加加、加顯、顯加、顯顯上位性效應(yīng)等各項(xiàng)遺傳主效應(yīng);運(yùn)用線性無(wú)偏預(yù)測(cè)法( lup )能夠無(wú)偏預(yù)測(cè)上述各項(xiàng)遺傳主效應(yīng)與環(huán)境的互作效應(yīng);基于qtl效應(yīng)的雜種優(yōu)勢(shì)預(yù)測(cè)也是無(wú)偏的。
