This study gave empirical evidence seventeen morpho-physiological and yield data that were collected from fifty five rice germplasm consisting of Oryza sativa lines including checks. The association of all morpho-physiological traits was estimated by phenotypic correlation coefficient and showed that thirteen variables were positively correlated. Principal component analysis resulted in the six components with eigen value greater than 1 accounting for 71.37% of the total variation. The derived information would be very useful to select potentially breeding lines for future rice improvement program.
