Variation Studies in Biomass Characters and Leaf Nutrients of Progenies of Different Provenances of Albizia lebbek

The present investigation on Albizia lebbek Benth was carried out to study the variation in some biomass and leaf nutrient characters of progenies of fifteen provenances from Himachal Pradesh. Analysis of variance revealed significant differences for all the characters viz; fresh shoot weight, dry shoot weight, fresh ischolar_main weight, dry ischolar_main weight, shoot ischolar_main ratio (fresh), shoot ischolar_main ratio (dry), nitrogen, phosphorus, potassium, calcium, magnesium and crude protein. High phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was observed for ischolar_main fresh weight i.e. 22.10 % and 20.70 %, respectively. High heritability (98.00 %) was estimated for both shoot dry weight and ischolar_main dry weight. As far as genetic gain is concerned it was found high for ischolar_main fresh weight (40.07 %).
