The present investigation entitled “Altitudinal variation in seed and nursery growth parameters in Dendrocalamus hamiltonii Nees in Himachal Pradesh.” was carried out in the Department of Tree Improvement and Genetic Resources. Field survey was carried out across the populations of Dendrocalamus hamiltonii Nees in different altitudinal zones of Himachal Pradesh. Flowering and morphometric traits were taken as selection criteria to select well-represented twelve seed sources viz. S1 (Jukhala), S2 (Sujanpurtira) S3 (Kallar), S4 (Chabutra) S5 (Sarkaghat) S6 (Ghumariwn), S7 (Toni Devi), S8 (Kuthar) S9 (Ratti) and S10 (Awah Devi), S11 (Giripul), S12 (Sapri). The clumps having flowering were randomly selected and the seeds were collected from individual clumps was done for studying the seed traits viz. 100 seed weight, seed length (mm), seed width (mm), Seed germination (%), Germination energy, Germination index, Germination value. The data analyzed by RCBD revealed that there was small variation between seed sources was observed for nursery growth parameters. The variation observed for seed traits did not follow any particular trend with regard to different populations. It is visualized that on altitudinal basis seed and germination parameters can be used as an effective tool for selecting genotypes for good quality seeds and seedlings from natural populations.
