Abstract excerpt

BACKGROUND: This study investigates the genetic basis of oil content, fatty acid (FA) composition, and seed yield in safflower (Carthamus tinctorius L.) to support breeding efforts aimed at improving oil quality and yield. A genome-wide association study (GWAS) was conducted on 262 safflower accessions using 4,545 SNP markers to identify genetic loci associated with oil-related traits. Additionally, RNA-seq was...
