Melhoramento genético da seringueira com ênfase na elevação da produtividade.

Abstract

The state of Pará, due to its location and territorial extension, presents different edaphoclimatic regions in which the behavior of clones is different due to their genotype x environment interaction. To obtain clones with satisfactory productive characteristics in our region, there is need for a rigorous selection process of new clones adapted to the different ecological conditions, and this is the main objective of the project under study. The trial was implemented using nine (09) clones selected from a small-scale experiment: IAN 8132, 8272, 8530, 8559, 8128, 7998, 8001, 8093, 8088 and the witness clone IAN 717, which showed good production and resistance to the fungus Microcyclus ulei. At the moment, the 8 plants obtained are bagged and are receiving the appropriate cultural treatments. Meanwhile, new nurseries were installed since the lack of "horses" made the grafting work difficult, as well as the scarcity of the cloning material itself, which is obtained from mother plants that were not "releasing bark". It should be noted, however, that the complementation of plants will take place during this year, since we have all the necessary conditions for the implementation of the trial.
