High-resolution quantitative trait loci mapping and pyramiding effects of candidate genes for plant height in soybean.

ABSTRACT: Plant height is a crucial agronomic trait that significantly influences plant architecture and yield in soybean (Glycine max (L.) Merr.). Identifying major genes regulating plant height and developing closely linked molecular markers are crucial for breeding soybean cultivars with ideal architecture. In this study, a recombinant inbred line (RIL) population (F_2:7-8) developed from a cross between two soybean cultivars with contrasting plant heights was used to conduct quantitative trait loci (QTL) mapping for plant height across five environments based on a high-density genetic linkage map. As a result, 13 QTL associated with plant height were identified on seven chromosomes. Among these, four QTL (qPH-5, qPH6-1, qPH18, and qPH19-2) were consistently detected across multiple env
