Popis: The seeds were collected from selected mother trees (ortets) one each at twenty seven locations and progenies were raised to study the extent and pattern of variation among biomass characters. The site S27 (Nauni), S14 (Ropar) and S11 (Jwalaji), showed better performance for these progeny traits as compared to others. High heritability with high genetic gain was observed for root dry weight (H= 0.88, GG= 88.49 %) and root fresh weight (H= 0.83, GG = 81.01 %) while high heritability with moderate genetic gain was found for shoot fresh weight (H= 0.87, GG= 64.84 %). Highly significant and positive genotypic and phenotypic correlations were observed for most of the characters.
