The ability to taste phenylthiocarbamide (PTC), a bitter chemical has long been known to be a bimodal autosomal trait inherited in a simple Mendelian recessive pattern which is being widely used for both genetic and anthropological studies. The frequency of taster and non- taster alleles is found to vary in different population. This study was taken to determine PTC taste sensitivity among Brahmin, Kshatriya, Vaishya and Shudra population of Lucknow and discussed it with reference to genetic variability. Unrelated individuals of both sexes belonging to four Varna populations were randomly selected and screened using serial dilution method of Harris and Kalmus (1949). The phenotypic frequency for PTC taste ability varies between four populations ; Brahmin (79%) were observed with highest taster frequency while Vaishya (72%) and Shudra (73%) had the lowest taster frequency. The tester frequency of four population showed that the percentage of tester frequency more frequent than that of the non-tasters. Kshatriya (7.25) and Brahmin (6.98) population showed highest PTC mean threshold while Shudras (5.86) had the least. In inter- Varna differences in terms of X2 Value 0.1622 is the highest value in comparison of Brahmin and Vaishya whereas 0.0034 is the lowest value in the comparison of Vaishya and Shudra Varna population.
