The present field work was done in order to study prevailing genetic diversity and to obtained information on the magnitude of variability of several morphological traits, predict heritability and genetic advance and estimate divergence in Doda and Kishtwar districts of Jammu region. A total of 50 Ambri apple trees were marked out of 150 trees explored in two districts situated at 1272 to 1798 above mean sea level. Out of fifty selected Ambri apple genotypes 70 per cent genotypes showed biennial, 24 per cent genotypes showed irregularity, 6 per cent genotypes were found regular and 24 per cent genotypes showed irregularity in flowering behaviour. In case of flower initiation, 32.00 per cent genotypes were early bloomers, 52.00 per cent genotypes were mid bloomers while rest 16.00 per cent genotypes were late bloomers. Regularity of flowering was categorised as regular (6 per cent), biennial (70 per cent), and irregular (24 per cent) among genotypes under study. On spur and mixed bearin

The present study highlights the presence of significant morphological variability among the Ambri apple accessions in Jammu region. All the observations made in this study will provide valuable evidence for decision making in characterization of Ambri apple germplasm and its management.
