The present study was conducted for assessing the variability, heritability and genetic advance estimates of upland rice varieties viz., Swarnaprabha and Vaisakh having susceptibility to lodging after treating with gamma rays of dose 375 - 550 Gy. The germination percentage, shoot and root length were inversely related to increase in radiation dose. Correlation studies pointed out that yield is having strong positive correlation with panicle length, panicles per plant, days to maturity and harvest index and direct selection for these independent characters can enhance the yield.
