No processo de produção comercial mudas gérbera, a cor da flor é uma das principais características morfológicas interesse agronômico, sendo característica importante em programas melhoramento genético. A utilização marcadores moleculares pode servir para direcionar cruzamentos, confirmar novos híbridos ou genótipos mutantes e identificar fins comerciais. Nesse contexto, o objetivo deste trabalho foi analisar divergência genética entre seis cultivares Gerbera jamesonii ('Jaguar Yellow',...
Objetivou-se neste trabalho, selecionar famílias de feijoeiro promissoras para a produtividade grãos com tipo ideal utilizando informações fenotípicas e marcadores moleculares ligados QTLs. Foram utilizadas 100 F3:7, avaliadas em três safras, dois experimentos/safra, totalizando seis experimentos. A primeira safra foi da seca/2007, na qual conduziu-se um experimento Lavras-MG o outro Ijaci-MG. Nas safras inverno/2007 águas 2007/2008, foram conduzidos, cada uma, Lambari-MG. Em todos eles...
Selecting appropriate donors and acquiring information about the genetic basis of inheritance is essential for breeding programs. In this study, a diallel cross was produced by crossing 15 progenies with five commercial lines wide diversity different rice traits (grain yield, plant height, days to flowering, panicle blast, brown spots, leaf scald, grain discoloration) in an incomplete design. The 20 parents 25 F2 crosses constituting were evaluated triple lattice design field test. analysis...
Objetivou-se determinar um protocolo de micropropagação por organogênese indireta em capítulos florais gérbera (Gerbera jamesonii Adlam) e comparar as características anatômicas folhas obtidas in vitro com mantidas condições vivo. Capítulos foram utilizados como fonte inicial explantes para a indução calos regeneração. As brotações enraizadas e, após 30 dias, plântulas aclimatizadas. Posteriormente, realizados estudos anatômicos provenientes do cultivo vivo vitro. Obtiveram-se média 3,2 6,6...
The purpose of this paper was to assess which environmental factor(s) (location, sowing season or years) in the common black bean genotypes interaction more expressive and verify existence with broad and/or specific adaptations season. Data grain yield thirteen were tested twelve trials value cultivation use during 2003 2004 south-central region Brazil. Analyses variance performed decomposition × environments interaction, allowed a partial isolation factors, subsequently, eight used complete...
Variação somaclonal é uma variação fenotípica de origem genética, ou seja, cromossômica que se torna herdável nas gerações seguintes, epigenética, transitória devido ao estresse fisiológico o material sofre, quando submetido cultivo in vitro. Um problema específico envolvendo a em bananeiras 'Prata Anã' foi observado Andradas, Minas Gerais, plantas oriundas micropropagação. A maior dificuldade na separação dos indivíduos normais e variantes os caracteres morfológicos, são inerentes este tipo...
BRS Catiana is an irrigated rice cultivar with a medium cycle and excellent grain quality, suited for cultivation in 17 Brazilian states. It has high yield potential (15,535 kg ha-1) mean of 7,253 ha-1, wide adaptation late senescence (stay green trait).
Fusarium wilt is a serious soil disease affecting common bean cultivation, especially crops under central pivot irrigation system.Our objective was to identify lines that combine resistance in the field with other desirable traits.Twenty-eight randomized block trials three replicates were conducted rainy, winter, and dry seasons from 2009 2012 states of Goiás, Federal District, Paraná.The composed six elite (one carioca five black grain type) selected previous study as resistant controlled...
A partnership program of Embrapa and BASF resulted in the development a new irrigated rice cultivar adapted to Clearfield® production system Rio Grande do Sul. The is tolerant imidazolinone herbicide kifix®. In field trials Sul it produced mean yield 8394 kg ha-1.
The lowland rice breeding program, developed in the state of Minas Gerais, has as basic objective to release new commercial cultivars. In this way, program is making available a cultivar named BRSMG Rubelita, which main characteristics: medium cycle, high tillering, lodging tolerance, diseases grain quality, and yield.
The aim of this study was to evaluate the phenotypic stability and specific broad adaptability common black bean genotypes for Central Center-South regions Brazil by using Annicchiarico AMMI (weighted average absolute scores: WAAS, weighted scores productivity: WAASP) methodologies. We carried out 69 trials, with 43 26 trials in regions, respectively. Thirteen were evaluated a randomized block design three replications, during rainy, dry, winter seasons 2 years. To obtain estimates...
Na produção de sementes, a secagem pós-colheita é um processo importante visando reduzir o grau umidade das sementes níveis seguros para armazenamento e manutenção da qualidade fisiológica. Diante disso, objetivou-se avaliar efeito temperatura na fisiológica feijão cultivar superprecose BRS FC104. Foi avaliado em estufa à constante 35ºC, 40ºC 45ºC, natural laboratório campo. Após os métodos secagem, as foram submetidas aos testes determinações do (GU), peso mil (PMS) germinação (G), primeira...
The lowland rice breeding program, developed in Minas Gerais state, has as basic objective to release new commercial cultivars. In this way, program is making available a cultivar named BRSMG Alterosa, which main characteristics: high grain yield, tillering, medium cicle, diseases tolerance and quality. It was recommended 2017.
The early-maturing irrigated rice cultivar BRS A702 CL was developed by Embrapa in partnership with BASF for the Clearfield Production System of tropical region Brazil. In states Tocantins and Roraima, produces a mean yield 7,650 kg ha-1.
The aim of this study was to select traditional accessions, compose a core collection common bean, and assess the representativeness in relation base accommodated BAG Embrapa using analysis strategies for multivariate models. We used data characterizing 2903 accessions from collections representing all geographic areas Brazil regarding three morphologic descriptors (seed color, growth habit type, seed size) four ecogeographic (geographical areas, states, altitudes, soil classes). A set 400...
variables.Descriptors were used to estimate the coefficient of similarity between two accessions and obtain dissimilarity distance semi-partial correlation squared values.Experiment I was comprised genetic material from 745 common beans planted in pots with three plants for each accession.In Experiment II, 240 selected I, using four accession.The phenotypic data this reduced group showed increased dissimilarity, contributing information research plant breeding farmers who may need seeds.The...
Abstract Rice is one of the most consumed cereals in world and extreme social economic importance Brazil. Minas Gerais leading State irrigated rice production Southeast Region. This study aimed to estimate genetic progress 26 years breeding programme Epamig Brazil by time meta‐analysis. Genetic was estimated for grain yield, plant height days flowering. The dataset understood 162 genotypes 91 trials value cultivation use seasons. rate annual gain yield .99% (49.85 kg year −1 ). It also...
