Haplotype-based insights into seminal root angle in barley.

ABSTRACT: Root system architecture (RSA) plays a crucial role in crop adaptation and yield stability, especially in the context of climate change and variable growing conditions. Despite this, the genetic basis of RSA remains poorly understood in barley (Hordeum vulgare L.), necessitating the need for more research to better characterize this architecture and explore the potential of diverse germplasm for trait improvement. In this study, we aimed to dissect the genetic basis of seminal root angle (SRA) by examining natural variation within a diverse global collection of 816 barley accessions, including both landraces and modern cultivars. Using a haplotype-based mapping approach, which reflects the recombination patterns considered in breeding programs, we identified chromosomal regions associated
