ABSTRACT Jambu is important nationally and internationally for its dietary medicinal use, notably espilanthol. Despite versatility, breeding work scarce. This study aimed to evaluate aerial traits estimate genetic parameters in jambu accesses support a program. The experiment was conducted greenhouse at the Universidade Federal da Amazônia, Capitão Poço campus. treatments included 172 genotype clones from seven municipalities Northeast mesoregion, obtained farmer’s market. Seedlings were...
Sweet sorghum has considerable potential for ethanol production due to its succulent stalks that contain directly fermentable sugars.Since many traits need be considered in the selection process breed superior cultivars production, then correlations between might of use help breeder define optimal improvement strategies.The aim this study was investigate association principal agro-industrial sweet sorghum, and evaluate direct indirect effects primary secondary on per hectare.In total, 45...
O objetivo deste trabalho foi determinar a estratégia seletiva mais adequada para o incremento simultâneo de componentes da produção frutos em açaizeiro (Euterpe oleracea). Implantou-se um experimento com 25 progênies meio-irmãos, no Município Santa Izabel, PA, tendo-se utilizado delineamento blocos ao acaso, quatro repetições e parcela cinco plantas. Os índices seleção Smith & Hazel, Williams, Mulamba Mock foram aplicados três estratégias seletivas. Foram utilizados, como pesos...
O conhecimento das correlações genéticas entre os principais caracteres utilizados no melhoramento de plantas serve base para delinear estratégias otimizadas seleção. procedimento da análise trilha permite refinar essas correlações, desdobrando-as em efeitos diretos e indiretos sobre o caráter principal. objetivo deste trabalho foi desdobrar as relativos ao cacho à produção frutos progênies meios-irmãos açaizeiro a total frutos, fim verificar melhor estratégia seleção obtenção mais...
The breeding program of Urochloa ruziziensis evaluates many genotypes in initial phases. Evaluations through grades might make the selection less costly. aim this study was to verify efficiency visual for green biomass yield relation different strategies, such as mass by phenotypic mean, BLUP (Best Linear Unbiased Prediction) and at random. For purpose, 2,309 regular were evaluated an augmented block design two cuts. evaluators gave plant vigor, later, plots measured yield. coincidences...
O objetivo deste trabalho foi avaliar a necessidade de bordadura e estimar o tamanho ótimo parcela em experimentos para avaliação Urochloa ruziziensis. Foram avaliadas altura das plantas produção massa verde oito progênies meio-irmãos U. ruziziensis, dois cortes. Utilizou-se delineamento blocos ao acaso, com quatro repetições parcelas 16 m². Cada subdividida 32 estratos 0,5 m², sendo cada estrato considerado como uma unidade básica. Para determinar bordadura, realizada análise variância,...
Abstract Ruzigass ( Urochloa ruziziensis ) is a forage crop with high agronomic and nutritional value. Plant breeders often assess ruzigrass phenotypic traits using vigor ratings. The analyses of these categorical data fail to meet usual statistical assumptions. In this study we compared four fittings linear models for rating analyses: i) mixed model the original scale (LMM), ii) Box-Cox transformed (BCLMM), iii) multinomial generalized (GLMM), iv) hierarchical Bayesian (HBM). Additionally,...
Forage plant breeders often use visual scores to assess agronomic traits because of the costs associated with in-depth phenotyping in initial stages breeding cycles. The aim this study was investigate impact number graders on effectiveness indirect selection high-yielding genotypes and determine an optimal early-stage trials Urochloa ruziziensis. For that purpose, five assessed 2.219 U. ruziziensis augmented block design. Biomass production vigor were evaluated two cuts analyzed using a...
The aim of this study was to use multivariate methods and Pearson partial correlations disregard phenotypic characteristics that contribute little differentiation between Brachiaria ruziziensis genotypes.Eighty-one genotypes B. were assessed in completely randomized blocks with three replications.Ten assessed: plant height, leaf length, width, sheath length the flower stem, inflorescence axis, number racemes per inflorescence, basal raceme, spikelets width rachis.The best traits for...
