Progeny Performance of Plus Trees of Toona ciliata M. Roem. under Nursery and Field Conditions

Progenies of 25 seed sources (plus trees) of Toona ciliata (Toon) collected from different seed zones of Himachal Pradesh were evaluated under nursery and field conditions. Analysis of variance for seedling height, collar diameter and number of leaves indicated significant mean squares for all the characters studied under nursery conditions. Seedling height and collar diameter after 120 days of sowing exhibited high heritability (broad sense) coupled with high genetic advance. Under field evaluation, seed sources viz. S₁, S₂, S₅ and S₆ exhibited faster growth rate based on the values of growth parameters.
