The research investigated the genetic correlations between agronomic traits within a variety of rice germplasm comprising 40 accessions, studied at various locations and cropping seasons. Correlation analysis revealed compelling associations among multiple plant traits. Genotypic correlation shed light on relationships involving panicle length, panicle length, plant height, leaf dimensions, effective correlation and yield. Meanwhile, the phenotypic correlation indicated a strong association between yield, panicle, days to maturity and days to flowering. In addition, he discovered the complexity among traits such as grain length, width and leaf dimensions. These findings were consistently reinforced by data obtained from different locations and years, confirming the fundamental role these traits play in determining yield and overall plant attributes across a wide variety of genotypes. In essence, this study underlines the key role of specific agronomic traits in influencing yield. Improving those traits could lead to improved yields, as evidenced by their index relationships. As such, she strongly advocates for further comprehensive research to elucidate the genome-wide links between these traits and yield, providing key insights into optimizing crop productivity.
