Abstract

The objective of this study was to evaluate the behavior of twelve hevea clones cultivated in northwest region of Minas Gerais State. The work was carried out in the Paracatu city. The experimental design was randomized blocks, made up by 12 hevea clones (Hevea brasiliensis Müell Arg.) (PB 235, PR 255, IAN 3193, IAN 3087, IAN 3156, IAN 2880, RRIM 600, RRIM 701, LCB 510, IAC 15, IPA 1 and GT 1), with four repetitions. The experimental plots were making up by eight plants, cultivated in the spacing 10 x 2m. At the 14 and 26 months post planting was evaluated the plants survival, circumference of the stem, height plants and the projection areas of crown (2nd evaluation). The increment in circumference of the stem and in height of plants were also determined. There was 100% of survival for all clones studied, on the two evaluations. The clones RRIM 600, IAC 15 and GT 1, with larger increment in height, and the clones GT 1, RRIM 701, PB 235 and PR 255, with bigger circumference of the stem increment, showed larger potential of growth. Due to plants height, the clones RRIM 600, IAC 15, GT 1 and PB 235 showed the best establishment capacity in the studied area.
