dc.description.abstractThis study was carried out in College of Forestry Ranichauri, Tehri Garhwal, (Uttarakhand) during Oct 2019 March 2020. Cones of C. deodara were collected from 10 different natural growing ranges of Uttarakhand, Himalaya. Cedrus deodara (Deodar) is an important industrial/commercial timber yielding tree. Cones of C. deodara were collected to understand the extent and pattern of variation in morphological characteristics of cones and seeds among the seed sources. Seeds were germinated under laboratory conditions to assess the effect of temperature on germination. On the basis of morphological variation among the seed sources broad sense heritability, genetic advance and genetic gain were estimated. Simple correlation was also calculated with geographical attributes. Significant variation (P 95% germination in Kandoliya, Dhanaulti, Dandachalli and Hulanakhal seed sources. It is also observed that seed germination decreases after three months of storage period. Altitude, latitude, longitude, temperature, rainfall, pH and electric conductivity had significant positive relationship with cone weight, cone length, seed thickness and number of seeds. Broad sense heritability (h2) calculated for different morphological characters and germination characters showed a considerable possibility of genetic evaluation for rapid genetic improvement of these traits. The variability appeared to be geographically structured and would be mainly genetically controlled. Based on cone, seed germination and seedling traits, Pauri, Dhanaulti and Dandachalli were the best seed source among the studied seed sources. Thus, the result of present study should be helpful for collecting quality seeds and producing quality planting material of this potential tree species for afforestation of temperate region of Garhwal Uttarakhand, Himalaya India.en_US
