Abstract: Present study revealed that polymorphic variants and their association with milk production traits at κ-casein gene (CNS3) locus in Malvi and Nimari, cattle. The frequency of A allele was found to be highest as compared to B allele in above both breeds of cattle under the study. Chi-square values for testing correspondence between observed and expected genotypic frequencies at this locus were found to be non-significant in both Malvi and Nimari breeds of cattle, indicating that the populations of these animals were in Hardy-Weinberg equilibrium at this locus. Association of polymorphic variants of κ -Casein (CSN3) gene with rotein (%) revealed that the mean protein per cent in the milk of AB genotype (4.02±0.15) of Nimari was significantly higher among the both AA and AB genotypes of Malvi.
