QTL mapping reveals key factors related to the isoflavone contents and agronomic traits of soybean (Glycine max).

ABSTRACT:

Background

Soybean is a valuable source of edible protein and oil, as well as secondary metabolites that can be used in food products, cosmetics, and medicines. However, because soybean isoflavone content is a quantitative trait influenced by polygenes and environmental interactions, its genetic basis remains unclear.

Results

This study was conducted to identify causal quantitative trait loci (QTLs) associated with soybean isoflavone contents. A mutant-based F₂ population (190 individuals) was created by crossing the Korean cultivar Hwanggeum with low isoflavone contents (1,558 µg g^-1) and the soybean mutant DB-088 with high isoflavone contents (6,393 µg g^-1). A linkage map (3,049 cM) with an average chromosome length of 152 cM was constructe
