Abstract: Acacia catechu Willd. commonly known as Khair has a place with family Fabaceae occurs in tropical moist deciduous forests, dry tropical forests and tropical thorn forests. The present investigation was directed to illuminate the pattern of variation in pod, seed characteristics and germination behaviour among Acacia catechu seed sources collected from different districts of Uttarakhand (viz. Dehradun, Rishikesh, Haridwar, Udham Singh Nagar and Nainital). All pod characters i.e. weight, length, breadth, number of seeds per pod and seed characters i.e. length, width, weight, thickness and seed volume were recorded. Germination parameters include germination percentage, germination value, germination period, germination speed, which varied significantly among different seed source. The variation observed among different seed source may probably be influenced by different intensities of natural constrains acting upon these traits in the prevailing geographic/climatic conditions. On the basis of pod weight (67.24), seed weight (29.70) and germination percentage (79.56) it was concluded that Udham Singh Nagar showed best results to develop selection criteria for tree improvement programmes for Uttarakhand. The present study is helpful in selecting a good source of superior seed quality for healthy seedlings. The significant variation observed among different seed sources may probably be influenced by different intensities of natural constraints acting upon these traits in the prevailing geographic/climatic conditions.
