Abstract

INDIRA, E. P. 2006. Provenance variations in Gmelina arborea with particular reference to tree form.
Provenance trials of Gmelina arborea were conducted to examine the extent of genetic variation in various
traits and to estimate the genetic gain by choosing the best provenances for raising plantations. Fourteen
provenances were collected from the main Gmelina growing areas in India. Growth performance, tree form
and the characters controlling them were studied. With respect to tree form, the provenances varied
significantly for clear bole percentage and tapering. Axis persistence, straightness and mode of branching
also had significant variation between provenances at one of the sites. The provenance, Khasi Hills, showed
the best performance at both sites for tree form as well as growth in the early years. The provenances
Baramura and Begur also showed good tree form.
