In order to evaluate the genetic divergence among soybean cultivars, an assay was carried out at Formoso do Araguaia, TO, Brazil, in off-season of 2007, irrigated lowland conditions. The experimental design were randomized blocks with 12 treatments and three replications. Genetic evaluated by multivariate procedures: Mahalanobis distance, Tocher clustering method's nearest neighbor method. It observed formation two distinct groups dendrogram dissimilarity, which identical those formed...
Ensaios conduzidos em condições de campo são premissas básicas para gerar informações úteis à recomendação uma cultivar determinada situação cultivo. Neste sentido, objetivou-se com o presente trabalho avaliar os atributos agronômicos nove cultivares comerciais soja na região central do estado Tocantins, safra 2014/2015. Foram avaliados altura planta, primeira vagem, dias florescimento, a maturação, estande inicial plantas, final massa mil grãos e produção grãos. Todas as apresentaram planta...
A avaliação de germoplasmas como ferramenta na busca genes que confiram resistência a doenças cultura do milho tem sido meta constante em programas melhoramento. Com esse intuito, determinou-se, por meio cruzamento dialélicos, capacidade geral (CGC) e específica (CEC) combinação para Puccinia polysora oito híbridos comerciais diferentes níveis adubação fosfatada. Cultivaram-se 56 combinações híbridas (F1s recíprocos) genitores dois ambientes distintos quanto à disponibilidade fósforo (baixo...
The fungus Corynespora cassiicola (Berk. & M.A. Curtis), the causal agent of target spot in soybean, have occurred frequently North Central region Brazil and may, under high temperature humidity conditions, cause serious damage to crop. As use chemical fungicides is recommended susceptible cultivars, objective this study was determine fungicide efficiency control soybean cerrado Tocantins, Brazil, crop 2014/2015. experimental design a randomized block with four replications. treatments were...
O melhoramento genético pode propiciar ganhos em produtividade, com o desenvolvimento de genótipos, explorando a variabilidade genética existente na cultura do milho.Outro fator, que aumenta eficiência nos programas melhoramento, é conhecimento da relação componentes produtivos e produtividade grãos.O objetivo deste trabalho foi avaliar variação genotípica produtivos, índices milho sua grãos.Entre as safras 2009/2010 2013/2014, foram conduzidos 24 experimentos sob delineamento blocos ao...
The parent selection for crossings is one of the most important steps in genetic improvement programs, which prediction potential hybrids allows breeder to channel human and financial resources at higher populations. In this sense, objective study was estimate general (GCA) specific combining ability (SCA) seven soybean genotypes, two generations (F1 F2), indicate parents hybrid combinations that are promising achieve new favorable combinations. F1 hybrids, F2 populations were evaluated city...
Recentes estimativas apontam que o estresse nutricional aflige áreas agrícolas ao longo do mundo pode levar à extinção precoce de reservas naturais fósforo, forma desenvolvimento genótipos milho eficientes no uso nutriente terá papel fundamental na agricultura.Neste sentido, objetivou-se com presente trabalho avaliar, por meio cruzamentos dialélicos, as capacidades geral (CGC) e específica (CEC) da combinação oito híbridos comerciais milho, em níveis distintos adubação fosfatada, intuito...
The soybean, the main crop in state of Tocantins, responds differentially to environment for agronomic characteristics, so that regionalized trials seasons planting should be performed.In this sense, considering importance season and scarcity studies soybean State eight competition were performed, being four 2014/15 harvest 2015/16 Porto national Santa Rosa -TO.The experimental design used each trial was a randomized block with three replications seven treatments (cultivars).The...
A existencia de elevada variabilidade genetica no germoplasma milho pipoca tropical, sugere a possibilidade em melhorar tanto para produtividade quanto capacidade expansao. Sabendo que o cerrado tocantinense apresenta condicoes propicias exploracao dessa cultura, objetivou-se com esse estudo avaliar potencial genetico familias 40 meios-irmaos nas do tocantinense. Para isso, foram recombinadas duas marcas comerciais pipoca, Produtos Paulista e Yoki. Utilizou-se delineamento blocos...
In order to determine the efficiency and response regarding use of phosphorus soybean cultivars, experiments were conducted in 2013/2014 season, evaluate 15 genotypes under two using a randomized complete block, with three replications. To simulate environments low high levels phosphorus, doses 40 120 kg.ha -1 P 2 O 5 applied. Characteristics evaluated for number pods per plant, grain yield methodology proposed by Fageria & Kluthcouski (1980), determined phosphorus. The environment...
The constant improvement of selection methods is necessary in order to optimize efficiency breeding programs for aluminum tolerance. Thus, the aim this study was establish a vase volume ideal semi-hydroponic cultivation forage grasses subjected stress by nutrient solution. experimental design completely randomized, with four replicates, each replicate consisting one plant per vase. treatments were arranged factorial 4x5, being first factor consists genotypes Brachiaria Humidicola; brizantha...
El objetivo fue evaluar la influencia de diferentes epocas y densidades siembra sobre el rendimiento soja ( Glycine max (L.) Merrill.) en region centro-sur Estado Tocantins. Cuatro ensayos se instalaron ano agricola 2008/09. diseno experimental bloques al azar con tres repeticiones 36 tratamientos. Los tratamientos fueron arreglados un factorial 3 x 2 2, que consta cultivares (M-SOY 9144 RR, M-SOY 8867 RR e P98Y70), tasas (6, 10 14 plantas por metro) dos fechas cada municipio. En Gurupi...
The study of genetic diversity allows the formation heterotic groups, which are important to direct crosses and derive segregating populations in breeding programs. In this sense, objective with was determine correlation between productive attributes, as well divergence half-sibling progenies popcorn corn conditions cerrado Tocantins, Brazil. For this, an experiment conducted at Universidade Federal do campusGurupi, a randomized block design three replicates, where treatments were composed...
Objetivou-se avaliar a influencia de diferentes epocas e densidades semeadura na produtividade graos soja ( Glycine max (L.) Merrill.) regiao centro-sul do Estado Tocantins. Foram instalados quatro ensaios no ano agricola 2008/09. O delineamento experimental utilizado foi blocos casualizados, com tres repeticoes 36 tratamentos. Os tratamentos foram dispostos num esquema fatorial 3 x 2 2, constituido por cultivares (M-SOY 9144 RR, M-SOY 8867 RR P98Y70), (6, 10 14 plantas metro linear), duas...
