This study was conducted in kharif, 2023 at the Indian Institute of Rice Research, Hyderabad, it involved 42 breeding lines and 3 checks in an Augmented Randomized Block Design. This study evaluates genetic variability, heritability, and genetic advance as percent of mean were recorded for all the traits, that revealed high PCV (22.16%) and GCV (20.96%) were recorded by grain yield per plant. Significant variability was observed in traits such as plant height, grain yield per plant, and kernel length, while high heritability coupled with genetic advance as percent of mean were noted for traits like plant height (96.20%;25.44%) and grain yield (89.48%;40.91%), indicating these characters could be improved through selection. Correlation analysis revealed that grain yield per plant shows a positive association with days to 50% flowering, plant height, panicle length, number of productive tillers, 1000 grain weight, hulling percentage, head rice recovery, kernel L/B ratio and amylose content suggesting importance should be given to these characters, during selection for improving yield and quality traits of aromatic short grain rice.
