Analyzing rice (Oryza sativa L.) panicle structure of 122 RILs using P-TRAP software for spikelet related traits

Panicle architecture is shown to have a direct impact on rice grain yield, making it an important characteristic for varietal improvement. In this study, we focus the Trait Phenotyping Tool (P-TRAP), freely accessible, platform-independent software analyzing panicle architecture, as one of ways generating comprehensive and reproducible structure data identifying superior breeding lines. analysis, structures 122 RILs along with their parents were analyzed using P-TRAP software. assesses nine spikelet characteristics its yield. All traits had positive significant associations influence The findings indicate that most characteristics’ coefficients variation lower values, exception number, area comparison other traits, standard error traits spikelet number yield a larger value. To better understand genetic basis, these quantitative can be exploited in genome-wide association analyses. Hence, crucial. tool preferred because reduces human effort provides shorter time span when compared traditional method. Keywords: Rice, spikelet, p-trap,
