Conteúdo: 	To determine the nature and extent of genetical and environmental control of vigour through annual girth increment in rubber trees [Hevea brasiliensis (Willd.ex Adr. de Juss.) Muell.Arg.], seven clones were studied in a replicated trial in Sao Paulo State at four different locations. The clones represented a range of imported germplasm while the locations were selected to represent a range of rubber growing areas. Trees were studied for annual girth increment over five years before the initiation of tapping for latex. The results of the analyses show a consistent decrease in genetic component over the five years from 10 per cent to 0,5 per cent with a corresponding increase in the effect of environment (19,0 per cent to 93,0 per cent). The genotype x environment effects from combined analysis were significant for three factor analysis of variance. Genetic correlation between locations for annual girth increment revealed a consistent positive and significant correlation between Mococa and Matao in the fifth year (r.=0,7128) Ribeirao Preto and Matao in the fifth year (r.=0,7113) and Ribeirao Preto and Presidente Prudente in the fourth year (r.=0,9367). The implications of these findings in selection of rubber for annual girth increment trait are discussed.
