Abstract
This study aimed to evaluate performance in a large-scale clonal field of rubber clones ( Hevea brasiliensis [Willd. ex Adr. de Juss.] Muell.-Arg.) IAN 710, IAN 873, FX 3864, RRIM 600, RRIM 703, PB 314, PB 312, PB 235, PR 255, PR 303 e IRCA 41 at 12 and 36 months of planting. Clonal materials were established using a randomized complete block design with 4 replications of 100 trees per clone. It was evaluated the growth in height and diameter. Clones that showed better diameter growth at 12 and 36 months were FX 3864 (2.13cm and 3.5cm) and IAN 710 (2.06cm and 3.63cm), those of smaller growth in diameter at 12 months were IAN 873 with 1.48 cm and PR255 with 1.47cm, while at 36 months was IAN 873 with 2.48cm. Respect to the total height IAN 710 (4.97m and 5.20m) presented the best growth at 12 and 36 months, while PR 255 with 2.21m and PR 303 with 2.12cm the lowest growth in 12 months and in 36 months IAN 873 slower growth with 2.82m.
