MAS is used in the IBERS oat breeding programme, largely based on predictions derived from a few markers linked to large effect quantitative trait loci (QTL).
Quantitative trait loci (QTL) approach is the source for plant breeders to scrutinize the complex traits like drought, temperature, salinity stress tolerance, etc.
In the first of two volumes, researchers from several botanical sciences discuss principles, techniques, and applications of plant biotechnology, covering its history, scope, and importance; plant tissue culture; techniques in molecular biology; and molecular markers and mapping quantitative trait loci.
With the advent of genome sequencing and genotyping platforms, genome-wide association studies (GWAS) have become a powerful tool and increasingly used to dissect the genetics of quantitative trait loci (QTL) in several domestic livestock species.
Given that these traits are quantitatively inherited, the discovery of the quantitative trait locus (QTL) plays a central role in improvement through marker-assisted selection (MAS) (Tuberosa & Salvi, 2006).

Topics include the stomatal regulation of plant water status, drought tolerance mechanisms and their molecular basis, the rice SUB1A transcription factor, root-associated stress response networks, genes and salinity tolerance, molecular and physiological mechanisms of plant tolerance to toxic metals, genomics, and quantitative trait loci and association mapping.
One of its chief applications nowadays is QTL analysis which deals with quantitative trait loci mapping.

In this study, we investigated the growth characteristics and physicochemical properties of a "Cheongcheong" x "Nagdong" double haploid (CNDH) population and performed the analysis of QTL to attempt to determine quantitative trait loci (QTLs) associated with the taste of cooked rice and breed a new variety that produces rice having good taste.
