The objective of this study was to evaluate the genotype x environment interaction and estimate genetic components variance mean using mixed models in early selection 238 clones Pinus taeda propagated by somatic embryogenesis. experiment consisted a complete blocks design, with 12 replications, one plant per plot, four environments, at 1, 3, 4 years age. Estimates heritability gains evaluated environments showed good prospects for superior genotypes. effect pronounced all traits...
ABSTRACT Wood characterization must be done in huge populations of Eucalyptus breeding programs order to efficiently select potential trees. In this study, benthamii wood was non-destructively characterized and the performance near infrared (NIR) spectroscopy estimating basic density, lignin, extractive, glucose, xylan contents total carbohydrates evaluated. NIR models for traits were performed from 481 trees E. progeny test (4-year-old) managed pulp cultivated Santa Catarina state, Southern...
Abstract The greatest challenge faced when breeding populations of forest species is to achieve the right equilibrium among genetic gain and no loss effective population size. Thus this study aims define best thinning strategy compose a seed orchard Eucalyptus benthamii obtain maintaining E. studied consisted 28 open-pollinated progenies. diameter at breast height (DBH) (H) parameters were determined three years after planting. Measurement data analyzed compared using four different...
Calophyllum brasiliense Camb. é uma espécie predominante de áreas com alta saturação hídrica, sendo comum nos ambientes cilares do sul Minas Gerais. Com o intuito se estudar a variabilidade genética dessa espécie, 20 indivíduos reprodutivos C. foram amostrados duas populações localizadas montante Reservatório Hidroelétrico Funil, localizado no Município Lavras,MG. A análise eletroforese isoenzimática permitiu obtenção 17 alelos, distribuídos entre oito locos, estes representados em cinco...
The objective of this study was to assess the genetic variability in two natural populations Calophyllum brasiliense located along different rivers state Minas Gerais, Brazil, using RAPD molecular markers. Eighty-two polymorphic fragments were amplified 27 primers. values obtained for Shannon index (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>I</mml:mi></mml:mrow></mml:math>) 0.513 and 0.530 on margins Rio Grande das Mortes, respectively, demonstrating...
ABSTRACT This study aimed to estimate the genetic correlation among selection ages (juvenile - adult) and efficiency of early for height, diameter, volume traits individuals from Pinus taeda families propagated via somatic embryogenesis. was carried out by genetic-statistical analysis, estimation procedure variance (Reml), prediction components breeding values (Blup), using Selegen-Reml/Blup software. Genetic correlations juvenile rotation age were performed applying linear model developed...
Esta pesquisa objetivou estimar a eficiência da seleção precoce em clones de Eucalyptus “urograndis”. Para isto, avaliou-se um teste clonal grandis W. Hill ex Maiden x urophylla S. T. Blake localizado no município Telêmaco Borba, PR. O diâmetro à altura do peito – DAP (centímetros) e ALT (metros) foram mensurados aos três nove anos meio idade. experimento foi delineado blocos completos casualizados com 68 tratamentos (Clones), sendo quatro testemunhas (materiais operacionais). Os ganhos...
Selecting individuals in breeding programs for pulp production, the physical and chemical wood traits must be considered genotype selection. In this study, trees from hybrid progeny tests of Corymbia torelliana x citriodora (CTOxCCT) progenies Eucalyptus dunnii (EDU) were investigated. Sawdust genetically selected standing was collected, classified prepared near infrared (NIR) spectra readings. The properties determined through kraft pulping. Predictive models each property developed based...
Eucalyptus benthamii is a fast-growing eucalypt with excellent potential as pulp and biomass crop in subtropical areas that are subject to occasional cold snaps. It among the most frost-tolerant of eucalypts has been deployed commercially selected regions North South America. Several relatively low-input domestication breeding programs underway. The species restricted natural range along Nepean River system west Sydney, Australia, facing ongoing threat due fragmentation caused by...
Objetivou-se com este trabalho avaliar a capacidade de propagação famílias dePinus taeda por embriogênese somática utilizando estimativas parâmetros genéticos. Para somática, foram selecionados cones imaturos 65 famílias-elite Pinus taeda. O germoplasma utilizado para implantação dos testes campo foi composto 238 clones 31 famílias. estudo realizado meio análise genetíoco-estatística pelo procedimento estimação componentes variância via máxima verossimilhança residual (Reml) e predição...
In this work, we analyzed the correlation between canopy coverage of two commercial clones Eucalyptus benthamii Maiden & Cambage and one dunnii their shoot yields in a clonal mini-garden system. By coverage, referred to area picture occupied by leaves (green area) when using computational resources. The was set up yield shoots on regular time schedule (between 20 30 days) obtain mini-cuttings for propagation. Pictures were taken at approximately cm above upper from plots containing...
This study aimed to estimate the genetic parameters of diameter at breast height over bark (DBHOB), percentage (Bark%) and correlation between DBHOB Bark% for Corymbia spp. Three independent trials were evaluated during this study: C. variegata (CV) mixed spotted gum species (CMSG) progeny measured 4-years age, (CSPP) from different seed sources 3-years age. The CV CMSG mainly comprised variegata, while CSPP consisted torelliana, maculata citriodora progenies. There significant differences...
The photosynthetic light-response curve reflects the instantaneous response of net rate to different gradients photosynthetically active radiation. Genetic materials can respond differently light and consequently alter productivity. Thus, this work aimed compare clones Eucalyptus benthamii dunnii by checking CO2 assimilation due increase in evaluations were carried out mini-stumps implanted a clonal mini-garden system. curves determined with aid portable photosynthesis meter. (A) radiation...
Eucalypts are economically important worldwide, being largely propagated by clonal means, that is, frequently achieved mini-cuttings. Regional climatic conditions, however, interfere with this strategy. Southern Brazil, especially in higher altitudes, has a considerable number of cloudy and cold days annually. It is challenge for propagation, even cold-tolerant species such as Eucalyptus benthami E. dunnii. The supplementation artificial light proved to be effective improving growth...
The main objective of this study was to investigate genetic control for individual volume and phenotypic correlation between trait measured at two different ages. We also assessed three selection intensities ( i = 1%, 5% 10%) understand the effects on gain effective size. Eight progeny tests were evaluated which included Corymbia citriodora subsp. (CCT), C. variegata (CCV), torelliana (CTO). Narrow-sense heritability [Formula: see text] ranged from 0.26 0.62 CCT tests, 0.07 0.21 CCV 0.14...
