In General the information available on various genetic variability components on different crops are based on single year's experimental data. when the result of those experimental data are assembled, wide differences among the values of those variability components are observed. The present experiment was designed in such way, with the expectation that the genotypic varibility estimated at different population level for a particular charcter will be more or less indentical in dimension and magnitude. Theoretically, it was expected that the differences in phenotypic varibility values at different population level for a particular character, if observed, mainly be contributed due to the differences in enviornmental factors. But from this experiment, close correspondences were obderved among environmental variability estimated at different population level for a particular trait. Comparatively wide differences in values both in magnitude and dimensions in some traits were observed in pooled population levels for different genotypic and phenotypic variability estimates. The results of the study clearly demand some modification or proposal of some new models for deducation of these variability components from the individual year as well as pooled population level to minimize the chance of such type of differences.
