Abstract: India has a pride possession of a large livestock wealth, both in terms of number as well as diversity. The activity of livestock production is largely confined to the rural sector. In the present study systematic record in respect to LMY, 300 DMY, PMY, DAPMY and LP was taken from the pedigree sheets and daily milk yield records maintained at CCBP farm. The records of 411 Holstein Friesian x Deoni crossbred over a period of 38 years were utilized for study. Heritability and genetic correlation was done by parental half-sib correlation method. In Holdeo cows medium to high heritability (h2) in respect of LMY, 300DMY, PMY, DAPMY and LP. The genetic correlations of 300 DMY, PMY and LP with LMY were positive and significant (P < 0.01). PMY and DAPMY with 300 DMY were positive and significant (P < 0.01). Whereas, LP was non-significant. DAPMY with PMY was negative and significant (P < 0.01). While, LP was non-significant. LP with DAPY was negative and significant (P < 0.01). The phenotypic correlations of 300 days milk yield with LMY was positive and significant (P < 0.01). However, PMY and LP were positive and non-significant and DAPMY was negative and non-significant. PMY and 300 DMY was positive and non-significant. Whereas, DAPMY and LP with 300 DMY were negative and non-significant. DAPMY with PMY and LP were positive and non-significant. LP with DAPMY was negative and non-significant.
