A set of 60 accessions of Garcinia indica (Choisy), comprised of two to five years old, established as part of ex-situ field gene bank at the College of Horticulture, Bengaluru were evaluated for growth and development related characters over two consecutive years, 2019-20 and 2020-21. A set of 11 growth traits significantly varied in their relative per cent increase over successive years. Among all the growth parameters, tree volume recorded a maximum per cent increase of 186.56 per cent. The

Plant height was 150cm in 2019 and 220cm in 2020 in GI_SIR7; 210cm -290cm in GI_DAN2, 320cm-380cm in GI_YAN4 and 330-410 in GI_KAN3, respectively in two, three, four and five-year-old age groups. The traits such as number of branches, length of the branch, number of leaves, stem girth, canopy spread East-West and tree volume increased gradually over two years of study. The results have significance in per se establishment of the species in non-traditional areas such as this agro-climatic zone.
