Abstract:
The present investigation entitled “Assessment of population structure genetic diversity through morphometric traits 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 natural populations 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 morphometric traits were studied. The data was analyzed by RCBD revealed that there was small variation observed between natural poulations for morphometric traits. The variation observed for morphometric traits did not follow any particular trend with regard to different populations. It is concluded that on altitudinal basis morphometric traits can be used as an effective tool for selecting genotypes for good quality seeds and seedlings from natural populations.
