Abstract

This study aimed to analyze the variation, correlation, and regional differences in key agronomic traits of foxtail millet (Setaria italica L.) collected from eight regions in Korea and China. A total of 53 foxtail millet accessions were evaluated for eight agronomic traits, including days to flowering (DTF), days to maturing (DTM), number of branches (NB), panicle length (PL), panicle width (PW), culm length (CL), stem thickness (ST), and 1,000-seed weight (SW). The analysis revealed positive correlations between the growth period (DTF and DTM) and structural traits such as CL, PL, and ST. In contrast, negative correlations were observed between the growth period and yield-related traits such as PW and SW. The results also highlighted regional selection practices, with foxtail millet accessions from southern regions exhibiting delayed flowering, thicker stems, and heavier seeds, reflecting local community preferences. Additionally, significant differences in panicle and leaf shape, leaf color intensity, and seed coat color were observed across regions, with specific forms favored by local populations. These findings demonstrate the influence of local preferences on the selection and maintenance of key traits in foxtail millet landraces and provide valuable insights for future breeding programs aimed at improving regional adaptability and trait optimization.
