EVALUATION OF NURSERY AND FIELD PERFORMANCE OF PROGENIES OF SELECTED PLUS TREES OF ALBIZIA CHINENSIS (SIRAN) UNDER MID-HILL CONDITIONS OF WESTERN HIMALAYAS

摘要

Progenies of 25 seed sources (plus trees) of Albizia chinensis collected from different seed zones of Himachal Pradesh were evaluated under nursery and field conditions. Analysis of variance for seedlings 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 condition, seed sources viz. S_1, S_2, S_55 and S_6 exhibited faster rate on the values of growth parameters.
