dc.description.abstractRoot system architecture, as a complex trait, has gained attention due to climate change and abiotic stress pressure on crops. The incorporation of root traits in breeding objectives may enable new advances in climate-resilient crops. Here, the genetics of the seedling root system architecture in the Synthetic W7984 x Opata M85 Doubled Haploid mapping population was investigated. Three traits at the seedling stage and mature stage root and shoot biomass traits were mapped for quantitative trait loci (QTL) identification. A total of five different loci on chromosomes 1B, 5A, and 7D with major effects were identified for total root length, primary root length, and seminal root growth angle. Four regions on chromosomes 2A, 5A, and 7D had colocating loci for seedling and mature stage root traits. Chromosome 5A, with a locus affecting most of the seedling root traits, is promising. The correlations between seedling and mature root traits, and newly identified QTL for seedling root traits, maybe promising to unravel the genetic structure of root traits and for the marker-assisted selection.
