Investigations were carried out during 2006 on 91 seedling trees of Persian walnut growing at high altitude (more than 300 mamsl.) at various locations of Ladakh region in India. Data were collected on 26 nut and kernel characters. A great magnitude of variability was noticed for various traits. Maximum coefficient of variability was recorded for kernel weight while minimum for nut width. Based upon the existing variability, selection criteria was made and elite genotypes were selected virk Tree No. 1 at Domkhar, Tree No. 1 and 2 at Nuda; Tree No.4 and 10 at Saspol and Tree No.4, 6, 9 and 19 at Khalsi. These selected types will be vegetatively propagated and released as cultivars for commercial cultivation in Ladakh region of India in future to boost the cultivation of walnut at high altitudes.
