Ladakh region includes Leh and Kargil districts of Jammu and Kashmir in India. The region is cold and arid limiting the growing of fruit crops. The study aims to characterize walnut diversity in the region which would be resourceful in the near future for various purposes and boost up walnut cultivation. Four genotypes are selected from various walnut growing areas of Ladakh viz. G1 from Skara, G2 from Nurla, G3 from Temisgam and G4 from Dhomkhar. It was evident that majority of the genotypes exhibited intermediate tree vigour with spreading nature of growth habit, glabrous shoot pubescence and leaf and rachis pubescence, strong shell seal and shell strength with good nut diameter and nut length, satisfactory kernel flavor, well filled kernel and easy removal of kernel halves. Leaflet shape observed was elliptic, leaflet margin was entire, green leaf and rachis colour, brown shoot colour, complete shell integrity and kernel plumpness was moderate in all the four genotypes. The branching habit was dense in genotypes G3 and G4, intermediate in G1 and intermediate to dense in G2. In general, the highest value of leaf length and kernel percentage was recorded in G2. G3 exhibited the maximum width of leaf, number of leaflets, inshell nut weight and kernel weight. The nut shape was broad to ovate in G2 and G3, while G1 was broad ovate and G4 was broad elliptic in shape. The shell texture of G2 and G4 was medium while G3 was medium to rough and G1 was rough. The shell colour of G1 was light, medium in G2, light to medium in G3 and medium to dark in G4. The shell thickness recorded the maximum in G4. The kernel colour was light in G2 and G4, while extra light and light to amber was observed in G1and

G3 respectively.
