Screening of promising clones of Gmelina arborea Roxb. at gene bank with higher productivity: a multipurpose tree species

Abstract

To study the screening of clone, 25 clones of Gmelina arborea were selected based on height, collar diameter, DBH, straightness of the stem and insect susceptibility from total seventy (70) numbers of clones. Among them, 25 numbers of clones were selected considering the above parameters. Selected clones shows the performance for the clone number GA017and GA39 is in the same position (height 22.13±0.64 m) as best performing best and GA106 and (height 21.45±0.86 m) is in second position and collar diameter GA017 (67.07±0.57 cm) and GA106 (68.30±0.48 cm) respectively. Wood density parameters of different clones at gene bank were estimated as minimum range of clone number GA044as fresh weight 0.65 gm, total length 4.10 cm, fresh volume 0.59 gm, dry weight 0.24 gm and the maximum range resulted in GA008 as fresh weight 1.27 gm, total length 7.77 cm, fresh volume 1.13 gm, dry weight 0.48 gm.
