The aim is to identify high-yielding rice genotypes through multivariate phenotypic profiling.
Evaluated ten quantitative traits in 187 advanced rice genotypes using an augmented block design.
Assessed genetic variability and trait interactions with ANOVA, correlation analysis, PCA, and hierarchical clustering.
Applied the Multi-Trait Genotype-Ideotype Distance Index (MGIDI) for ideotype excellence assessment.
Filled grains per panicle had the highest genotypic (28.59%) and phenotypic (34.74%) coefficients of variation.
Grain yield showed significant positive correlations with plant height (0.34***) and days to maturity (0.31***).
MGIDI identified 28 promising genotypes, with G135, G3, and G131 as the most superior.
