Qtl mapping thesis
Soybean (glycine max l merr) is the world's foremost source of edible plant oil and proteins, meantime, the biologically active secondary metabolites such as saponins and isoflavones are benefit to human healththe objective of this study was to identify quantitative trait loci (qtl) and epistatic interactions associated with isoflavone, protein, and oil contents in soybean seeds.

Qtl mapping thesis
Mapping of quantitative trait loci associated with levels of individual metabolites (mqtl) was combined with the mapping of agronomic traits to investigate the genetic basis of variation and co-variation in metabolites, agronomic traits, and plant phenology in a field-grown bread wheat population. Qtl mapping of economically important components of yield and quality can therefore be expected to facilitate more efficient incremental improvement of specific individual target traits in applied crop breeding programs.
