The selection of plus tree candidate is considered an important and first step in the tree improvement programme. A total of 61 candidate plus trees of Gmelina arborea were selected from a 25- year-old plantation forest in Simen Chapori, Nari Forest Range under Pasighat Forest Division, Arunachal Pradesh. From these selected CPTs, 28 plus trees (PTs) were screened out based on their total index value (>average). The qualitative and quantitative traits of economic interest considered for selection were height, CBH, DBH, CD, stem straightness, branching behaviour, pest and disease free, lower forking, etc. The mean value of CPTs for height, CBH, DBH, CD, stem straightness, and branching behaviour were 24.54 m, 18.88 m, 49.41 cm, 69.70 cm, 3.59, and 3.61, respectively, and for plus trees were 27.29 m, 21.22 m, 51.81 cm, 75.01 cm, 3.89, and 3.93. The percent improvements by PTs were 11.22% for height, 12.38% for CBH, 4.86% for DBH, 7.62% for CD, 8.43% for straightness, and 8.93% for branching. The selected plus trees shall be useful in developing high quality planting material for mass propagation and future tree improvement programmes.
