SUMMARY:
Genetic improvement programs for species native to the Atlantic Forest biome require the development of methodologies capable of reducing the time of improvement cycles and enabling the discovery of superior individuals more quickly. Among the techniques applied, rescuing genotypes through grafting and pollen processing are strategies that facilitate controlled crossings, increasing genetic gains per unit of time. The objectives of the present work were: a) to estimate genetic parameters in testing provenances and progenies of brown laurel, b) to establish a clonal recombination orchard, and c) to test and adapt methodologies for processing pollen used in eucalyptus for brown laurel. From genetic analysis, the 10 superior Louro-pardo genotypes were selected by genetic analysis and 10 genotypes through phenotypic analysis, which were rescued through grafting to form an indoor recombination orchard. To process Louro-pardo pollen, the methodology already established for obtaining eucalyptus pollen was adapted. The genetic analysis showed that DAP and total height were the characters with the highest heritability. The correlation between genotypic and phenotypic selection was 60%. Pollen collection required adaptations to the methodology already established for eucalyptus. With this work it was possible to contribute to the reduction of forest improvement cycles for native species to enable genetic programs for these species, in addition to helping to maintain the genetic diversity of Louro-pardo.
