- 一方面,随着后基因时代的到来和生物信息的迅速发展,数量性状基因(Quantitative Trait Loci,简称QTL)定位领域发展迅速。Nowadays, since the bioinformatics and genetic science are making rapid progresses, the Quantitative Trait Loci (QTL) grows into a hot researching area.
- DNA分子标记可把复杂的数量性状分解成若干个数量性状位点(quantitative trait loci,QTL)的效应,并将QTL转入到栽培品系中去。In genetics, the advent of molecular markers enables the dissection of a complex trait into a number of quantitative trait loci (QTL), and assists the transfer of these QTL into desired cultivars or lines.
