Resumo: The objective of this work was to evaluate the performance of 15 clones of the IAC 500 series of Hevea brasiliensis, developed at Instituto Agronômico (IAC), over a 12-year period, in the northwest region of São Paulo State, Brazil. The 15 new clones evaluated are primary clones obtained from selected ortets within half-sib progenies. The clone RRIM 600, of Malaysian origin, was used as the control. Dry rubber yield performance over a four-year period, mean girth at the tenth year, girth increment before and during tapping, thermal properties of the natural rubber produced and other characters of the laticiferous system were evaluated. Forty percent of the clones were superior in comparison to the control for yield. Clone IAC 500 recorded the highest yield (66.81 g per tree per tapping) over four years of tapping, followed by IAC 502 (62.37 g per tree per tapping), whereas the control recorded 48.71 g per tree per tapping. All selected clones were vigorous in growth. The natural rubber from this IAC clones showed thermal stability up to 300ºC. No differences were observed in the thermal behavior of rubber among the IAC series and the RRIM 600 clones. The clones IAC 500, IAC 501, IAC 502, IAC 503 and IAC 506 are the more promising for small-scale plantations, due to growth and yield potential.

Os 15 novos clones avaliados são clones primários resultantes de ortetes selecionados dentro de progênies de meios-irmãos. O clone RRIM 600, de origem Malaia, foi usado como testemunha. Foram avaliados: desempenho da produção por um período de quatro anos, média do perímetro do caule no décimo ano, incremento anual do perímetro antes e durante a sangria, propriedades térmicas da borracha natural produzida e outros caracteres do sistema laticífero. Quarenta por cento dos clones foram superiores em produção, em comparação ao clone RRIM 600. O clone IAC 500 registrou a maior produção (66,81 g por árvore por sangria) em quatro anos de sangria, seguido pelo IAC 502 (62,37 g por árvore por sangria), enquanto o clone testemunha registrou 48,71 g por árvore por sangria. Todos os clones selecionados apresentaram crescimento vigoroso. As borrachas avaliadas apresentaram estabilidade térmica até cerca de 300ºC. Não foram observadas diferenças no comportamento térmico entre os clones da série IAC e o RRIM 600. Os clones IAC 500, IAC 501, IAC 502, IAC 503 e IAC 506 são mais promissores para plantações em pequena escala, em virtude de seu crescimento e potencial produtivo.
