The objeetive ofthis study was to seleet Pinus kesya prog enies by lhe estimation of g enetic p arameters using lhe method of restricted maximum likelihood (Remi) and prediction of additive genetic values by the best linear unbiased prediction (Blup ). The Pinus kesya progeny tesl was installed in randomized b/oeks. which consist ed of 30 progenies and three replications. Tlze twenty-year-old trees were evaluated for lhe traits diameter at breast heiglit (DBH), height (HT) and st em form (FOR). The DBH, HT and FOR means \Vere, respectively, 21.89 em, 21.89111 and 1.56 and their respective mean herit ability estimares of progenies were 0.58, 0.39 and 0.66. DBH presented the highest coefficient of additive genetic variation (17.89%). Tlze selection ofthe 80 best t rees whicli belon ged 1021 progenies provided a gain 0/,9.62%for FOR witli a mean of 3.81 trees selected per prog eny, an effective population si:e 0/,30.86 and g enetic diverg ence ofO.37. |

Coffea canephora genotypes from the breeding program of Instituto Capixaba de Pesquisa e Extensão Rural were evaluated, and genetic diversity was estimated with the aim of future improvement strategies. From an initial group of 55 genotypes, 18 from the region of Castelo, ES, were selected, and three clones of the cultivars ?Vitória? and ?robusta tropical.? Upon completion of the scheduled cycle pruning, 17 morphoagronomic traits were measured in the 22 genotypes selected. The principal components method was used to evaluate the contributions relative to the traits. The genetic dissimilarity matrix was obtained through Mahalanobis generalized distance, and genotypes were grouped using the hierarchical method based on the mean of the distances. The most promising clones of Avaliação Castelo were AC02, AC03, AC12, AC13, AC22, AC24, AC26, AC27, AC28, AC29, AC30, AC35, AC36, AC37, AC39, AC40, AC43, and AC46. These methods detected high genetic variability, grouping, by similarity, the genotypes in five groups. The trait that contributed the least to genetic divergence was the number of leaves in plagiotropic branches; however, this was not eliminated, because discarding it altered the groups. There are superior genotypes with potential for use in the next stages of the breeding program, aimed at both the composition of clonal variety and hybridizations |
