Description :
Present study revealed that polymorphic variants and their association with milk production traits at κ-casein gene (CNS3) locus in Malvi and Nimari, cattle. Association of polymorphic variants of κ -Casein (CSN3) gene revealed that the frequencies of AA are higher as compared to AB and BB genotypes. The frequency of A allele was found to be highest as compared to B allele in all the 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 Malvi, Nimari breeds of cattle, indicating that the populations of these animals were in Hardy-Weinberg equilibrium at this locus. The analysis of variance showed significant (P<0.01) effect of breed on SNF (%).The mean SNF per cent of Malvi was significantly lower than Nimari cattle. The maximum SNF per cent was noticed in Nimari breed of cattle.
