Abstract:

Present study was based on three genetic groups viz., Jersey × Local (G1), Holstein Friesian × Local (G2) and Local (G3) cows, data collected from the field condition of Allahabad district, to determine the effect of service period, gestation period and calving interval. High estimates of heritability (above 60%) in broad sense were recorded for tall the characters under study. High heritability was observed for all traits viz.; service period according to genetic group (70.79%), calving interval according to genetic group (81.95%). Genetic distance plays a vital role, as parental diversity in optimum magnitude is required to obtain superior genotypes in segregating population. The crossing programme should be initiated between the genotypes belonging to more divergent clusters. The greater the distance between to clusters, the wider the genetic diversity between their genotypes.
