An experiment with a total of 36 rice entries consisted of 28 cross and eight parental lines were evaluated to estimate the variability parameters for 10 yield attributing character, 6 physical quality traits; 8 cooking and chemical quality traits of rice cultures. Analysis of variance revealed the existence of significant differences among cultures for all traits studied. High PCV coupled with GCV was recorded for gel consistency and alkali spreading value revealed wider variability for these traits. Moderate PCV and GCV was observed for total number of tillers per plant, number of grains per panicle, LAI at maximum tillering stage, volume expansion ratio, water uptake, amylose content and grain yield per plant indicating the moderate variability.
