| The increasing demand for raw material for multiple uses of forest products and by-products has attracted the interest for fast growing species, such as the Australian Cedar (Toona ciliata), which presents high productive and economic potential. The present work aimed at estimating genetic diversity by DNA markers and morphological traits supported for the mixed models. The following traits were measured and genotypes were sampled randomly in different areas: diameter at breast height, height, cylindrical volume, diameter, distance between nodes and crown diameter. Twelve RAPD primers were used and generated a total of 91 marks, 82 of which were polymorphic. The high percentage of polymorphic markers, 90.10%, demonstrated that discrimination in this... |

| Objetivou-se, neste trabalho, estimar parâmetros genéticos e correlações associadas a características agronômicas do maracujazeiro amarelo (Passiflora edulis Sims), predizer o progresso genético esperado com a seleção direta e baseado em índice de seleção, bem como sugerir uma estratégia de capitalização de ganhos genéticos nos ciclos de seleção recorrente. Foram avaliadas 26 progênies de meio-irmãos provenientes da recombinação de genótipos selecionados do primeiro ciclo de seleção via Delineamento I, as quais representam a população melhorada, UENF/MA1. O delineamento estatístico utilizado foi blocos casualizados com duas repetições e parcelas constituídas de cinco plantas. Foram avaliadas cinco características relacionadas ao fruto, no período de... |

| The failure to obtain the ideal stand is one of the causes of decreased crop yields, in this sense it is important to investigate the genetic effects related to seed quality. The aim of this study was to measure the general combining ability (GCA), the specific combining ability (SCA) and the reciprocal effects (RE) for popcorn seed quality in addition to evaluate the association between germination and vigor tests with field emergencein order to identify hybrids with better germination and vigour. Ten inbred lines were evaluated using a complete diallel cross with reciprocals. Seed quality was measured by germination tests (GT) and by modified cold vigour tests (MCV). In the GT, the numbers of strong normal seedlings (SNS), weak normal (WNS), abnormal... |
