Resumo: The objective of this work was to evaluate the performance of 12 combinations ​​of three rubber tree panel clones (PB 311, PB 314, and RRIM 600) and four crown clones (F 4512, MDF 180, IAN 6158, and IAN 6543) grown in the southwest of the state of Mato Grosso, Brazil. A randomized complete block design was used, with four replicates. The following were evaluated: dry rubber yield, percentage of tappable trees, tapping panel dryness, nutritional status, dry rubber content, Wallace plasticity (P0 and P30), plasticity retention index, and Mooney viscosity. The combinations of the crowns IAN 6543 and MDF 180 with the panels PB 311, RRIM 600, and PB 314 showed adequate nutritional status, with dry rubber yield greater than 1.41 Mg ha-1 per year. The crown clone IAN 6158 provided, over eight years, the highest number of plants suitable for tapping. The panel/crown combinations showed low incidence of tapping panel dryness, except PB 311 x IAN 6158. The rubber of the 12 panel/crown combinations shows good resistance to thermal degradation and high plasticity retention.

Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições. Foram avaliados: produção de borracha seca, percentagem de plantas aptas à sangria, secamento de painel, estado nutricional, teor de borracha seca, plasticidade Wallace (P0 e P30), índice de retenção de plasticidade e viscosidade Mooney. As combinações das copas IAN 6543 e MDF 180 com os painéis PB 311, RRIM 600 e PB 314 apresentaram estado nutricional adequado, com produtividade de borracha seca acima de 1,41 Mg ha-1 por ano. O clone de copa IAN 6158 propiciou, em oito anos, as maiores quantidades de plantas aptas à sangria. As combinações painel/copa apresentaram baixa incidência de secamento de painel, exceto PB 311 x IAN 6158. As borrachas das 12 combinações painel/copa apresentam boa resistência à degradação térmica e alta retenção de plasticidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmbrapa, Grupo Guaporé AgropecuáriaMoraes, Vicente Haroldo de FigueiredoMoraes, Larissa Alexandra CardosoMoreira, AdônisSouza, Nilson Pereira deYokoyama, RobertoPereira, Ailton VitorFialho, Josefino de Freitas2013-09-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15571Pesquisa Agropecuaria Brasileira; v.48, n.6, jun. 2013; 597-604Pesquisa Agropecuária Brasileira; v.48, n.6, jun. 2013; 597-6041678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15571/12150info:eu-repo/semantics/openAccess2013-09-05T19:39:27Zoai:ojs.seer.sct.embrapa.br:article/15571Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-09-05T19:39:27Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
