Abstract: A survey was conducted in cold desert of Spiti Valley, Himachal Pradesh to assess morphometric and chemical seed oil traits diversity of Hippophae rhamnoides population. Nine major gene pool areas and three growing conditions within major gene pool areas selected for the study showed wide variation among different morphological, biochemical and leaf proximate compositions traits. On the basis of results, eventually, it may be concluded that GPA-3(Sheigo) was superior than other major gene pool areas for morphometric traits and seed oil chemical traits among different major gene pool areas. Over all GC-3 (crop land) was found superior for all morphometric traits and seed oil chemical traits among different growing conditions among different major gene pool areas. For seed oil evaluation Maximum per cent seed oil (5.23) was recorded in GPA-3 (Sheigo) while minimum plant height (4.25) was recorded in GPA-9 (Hurling) gene pool area. On the other hand, Maximum per cent seed oil (4.91) was recorded for GC-3 (crop land) which shows significant variation among different growing conditions. Maximum acid value(4.77 mg KOH/g), saponification value (231.51 mg KOH/g), and iodine value (151.37g I2/ 100 g) was recorded for GPA-3 (Sheigo) major gene pool area, and 4.91 mg KOH/g, 216.61 mg KOH/g and 146.37 g I2/ 100 g respectively for GC-3 (crop land) growing condition. Based on morphometric traits and exists in naturally growing populations of Hippophae rhamnoides in the Spiti Valley of Himachal Pradesh, and this morphological variation can be exploited for the further selection of suitable genotypes to accelerate the domestication process of this important species.
