Abstract:
An experiment was conducted to detect the genetic parameters such as variability, heritability and genetic advance for morpho-physiologcal and yield related traits in rice under drought stress. For this study, 30 genotypes were screened using PEG in laboratory and 21 genotypes and phenotyped for drought tolerance under field condition in CRD at FSRS, Sadanandapuram during 2019-21. The result obtained from the current study showed that adequate variability was present among the genotypes for morpho-physiological and yield parameters. For all traits tested, the phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV). High GCV and PCV were observed for yield plant.
