VELEZ-SANCHEZ, Diego Fernando  e  NIETO-RODRIGUEZ, Víctor Manuel. Early growth performance of Rubber clones in Puerto Carreño, Vichada, Colombia. Colomb. for. [online]. 2013, vol.16, n.2, pp.186-199. ISSN 0120-0739.

ABSTRACT This study evaluated the performance of eleven rubber clones (Hevea brasiliensis) in a large-scale clonal field 12 and 36 months after planting. Clonal materials were established using a randomized complete block design with four replications of 100 trees per clone. Growth in height and circumference were evaluated. The clones that showed the greatest circumference growth at 12 and 36 months were FX 3864 (6,69 cm and 10,99 cm) and IAN 710 (6,48 cm and 11,41 cm), those with lesser growth in circumference at 12 months were IAN 873 with 4.65 cm and PR255 with 4,61 cm, while the clone with least growth at 36 months was IAN 873 with 7,80 cm. IAN 710 (4,97 m and 5,20 m) had the best growth in height at 12 and 36 months, while PR 255 with 2,21 m and PR 303 with 2,12 cm had the lowest height growth at 12 months and at 36 months IAN 873 had least growth with 2,82 m.
