The present study was done to evaluated the diversity of Ambri apple germplasm in Jammu region and to select elite Ambri apple genotypes possessing superior attributes. Fifty Ambri apple genotypes were collected from different locations in Jammu and their various morphological characters were studied. The genotypes showed wide variability with respect to tree and leaf characteristics. Studies on tree habit revealed substantial variability among the seedling raised Ambri apple genotypes. In the present investigation it was found that out of 50 Ambri apple genotypes (44 %) had upright tree habit while (46 %) had spreading and rest (10 %) genotypes had drooping tree habit. In case of tree vigour among the 50 selected Ambri apple genotypes none of the genotypes had extremely weak vigour, while (8 %) had weak tree vigour, (50 %) had intermediate, (38 %), had vigorous and rest (4 %) had very vigorous tree vigour. In case of leaf shape among the selected 50 Ambri apple genotypes (8 %) exhibi

The purpose of our study was to obtain diversity in Ambri apple and present study confirmed that there is huge diversity of Ambri apple in North western Himalayan region. Thus it become necessary to preserve these unique genetic resources for improvement of fruit quality parameters. And for continuing its study to ensure its conservation, exchange and utilization in future breeding programmes for future development of innovative, market-driven cultivars through adoption of effective genetic approach.
