Avaliação de acessos de mandioca quanto ao teor de ácido cianídrico em raízes frescas. Repositório Alice
ZAGO, B. W.; HOOGERHEIDE, E. S. S.; SILVA, B. R. da; BARELLI, M. A. A..
A mandioca é considerada a espécie cianogênica mais importante do Brasil, sendo classificada pela taxonomia popular em bravas e mansas dependendo do teor de ácido cianídrico encontrado nas raízes. Este componente varia substancialmente em razão da variedade, mas pode variar também, em menor escala, em relação as condições de cultivo, época de colheita e condições ambientais. As mandiocas consideradas bravas têm sabor amargo, e elevado teor de glicosídeos cianogênicos, e podem ser consumidas após o processamento. As consideradas mansas não têm sabor amargo, contêm baixo teor de glicosídeos cianogênicos e podem ser consumidas com ou sem qualquer processamento. Com a finalidade de colaborar na seleção de novas cultivares de mandioca para o consumo ?in...

VENDRUSCOLO, T. P. S.; BARELLI, M. A. A.; CASTRILLON, M A. S.; SILVA, R. S. da; OLIVEIRA, F. T. de; CORRÊA, C. L.; ZAGO, B. W.; TARDIN, F. D..
Sorghum biomass is an interesting raw material for bioenergy production due to its versatility, potential of being a renewable energy source, and low-cost of production. The objective of this study was to evaluate the genetic variability of biomass sorghum genotypes and to estimate genotypic, phenotypic, and environmental correlations, and direct and indirect effects of seven agronomic traits through path analysis. Thirty-four biomass sorghum genotypes and two forage sorghum genotypes were cultivated in a randomized block design with three replicates. The following morpho-agronomic traits were evaluated: flowering date, stem diameter, number of stems, plant height, number of leaves, green mass production, and dry matter production. There were significant...

Genetic diversity among cassava genotypes (Manihot esculenta crantz) collected in the south-central mesoregion of the state of Mato Grosso-Brazil. Repositório Alice
ZAGO, B. W.; BARELLI, M. A. A.; SILVA, V. P. da; AZEVEDO, R. F.; CORRÊA, C. L.; NEVES, L. G.; HOOGERHEIDE, E. S. S..
The aim of this research was to evaluate the genetic divergence between 164 genotypes of Manihot esculenta from the South-Central mesoregion of the State of Mato Grosso. The genotypes are from projects conducted by the Laboratory of Genetic Resources & Biotechnology of the University of the State of Mato Grosso, Cáceres-Mato Grosso (UNEMAT), and the Brazilian Public Agricultural Research Corporation - Agrosilvopastoral (EMBRAPA). The agronomic descriptors evaluated were plant height, height of first branching, branching levels, weight of the aerial part of the plant, total weight of the plant, number of roots per plant, average weight of roots per plant, yield of commercial roots, yield of non-commercial roots, number of rotten roots per plant and...

Genetic variability of Colletotrichum sublineolum through ISSR markers. Repositório Alice
GUIMARÃES, T. S.; BARELLI, M. A. A.; CORREA, C. L.; SILVA, V. P. da; FLORIANO, A. J. S.; SANDER, N. L.; DUARTE, A. V. M.; ZAGO, B. W.; RIBEIRO, J. L. B.; TARDIN, F. D.; SILVA, D. D. da.
The occurrence of diseases is a limiting factor in the development of sorghum crop. Among the diseases that causes losses in sorghum production, anthracnose is the main and most severe, mainly by the genetic variability of the pathogen. In this context, the aim of this study was to evaluate the genetic variability of Colletotrichum sublineolum isolates. DNA were extracted from 56 monosporic isolates of C. sublineolum using a DNA extraction kit, and to perform the analysis of genetic diversity of the isolates were used ISSR primers. After amplification, it was determined the polymorphic information content (PIC), allelic frequency, UPGMA and Tocher clustering analyzes and, using software Structure, the genetic structure. According to the descriptive...

Genetic variability of garlic accessions as revealed by agro-morphological traits evaluated under different environments. Repositório Alice
HOOGERHEIDE, E. S. S.; AZEVEDO FILHO, J. A.; VENCOVSKY, R.; ZUCCHI, M. I.; ZAGO, B. W.; PINHEIRO, B. J..
The cultivated garlic (Allium sativum L.) displays a wide phenotypic diversity, which is derived from natural mutations and phenotypic plasticity, due to dependence on soil type, moisture, latitude, altitude and cultural practices, leading to a large number of cultivars. This study aimed to evaluate the genetic variability shown by 63 garlic accessions belonging to Instituto Agronômico de Campinas and the Escola Superior de Agricultura ?Luiz de Queiroz? germplasm collections. We evaluated ten quantitative characters in experimental trials conducted under two localities of the State of São Paulo: Monte Alegre do Sul and Piracicaba, during the agricultural year of 2007, in a randomized blocks design with five replications. The Mahalanobis distance was used...

Morphological diversity of cassava accessions of the south-central mesoregion of the State of Mato Grosso, Brazil. Repositório Alice
ZAGO, B. W.; BARELLI, M. A. A.; HOOGERHEIDE, E. S. S.; CORRÊA, C. L.; DELFORNO, G. I. S.; SILVA, C. J. da.
Genetic variability of cassava (Manihot esculenta Crantz) in Brazil is wide, being this the result of natural and cultural selection during pre- and post-domestication of the species in different environments. Given the number of species of the genus found in the region (38 of a total of 98 species), the central region of Brazil was defined as the primary center of cassava diversity. Therefore, genetic diversity characterization of cassava accessions is fundamental, both for farmers and for plant breeders, because it allows the organization of genetic resources and better utilization of available genetic diversity. This research aims to assess genetic divergence of cassava accessions from the south-central region of the State of Mato Grosso, based on...

Multicategorical variables for determining the genetic divergence among biomass and saccharin sorghum genotypes. Repositório Alice
CASTRILLON, M. A. de S.; BARELLI, M. A. A.; VENDRUSCOLO, T. P. S.; SILVA, R. S. da; OLIVEIRA, F. T. de; LIMA, C. C.; ZAGO, B. W.; TARDIN, F. D..
This study aimed to evaluate the genetic diversity of biomass and saccharin sorghum genotypes, based on 19 agronomic traits by the means of multicategorical variables. The experiment was conducted in the experimental area of the University of the State of Mato Grosso/UNEMAT, in Cáceres. We evaluated 25 genotypes of saccharin sorghum and 36 genotypes of biomass sorghum, in a randomized complete-block design with three replications. The data were submitted to three clustering methods, Tocher optimization, UPGMA hierarchical and Projection distances in 3D plan and comparing their results. The study showed the most divergent genotypes and the behavior of the three methods, which have proved partially concordant in the grouping of genotypes. The combined use of...

CASTRILLON, M. A. S.; BARELLI, M. A. A.; CORREA, C. L.; SILVA, V. P.; ALMICI, M. S.; VENDRUSCOLO, T. P. S.; SILVA, R. S.; ZAGO, B. W.; DUARTE, A. V. M.; SILVA, D. D. da; ARAUJO, K. L.; COTA, L. V.; TARDIN, F. D..
The objective of this work was to evaluate the reaction of biomass and saccharin sorghum genotypes to a isolate of the Ramulispora sorghi. The experiment was conducted in a completely randomized design with three replications in a greenhouse. The variables analyzed were: area below the disease curve progress; lesion length (LL), lesions width (LW); normalized area below the curve of the lesion area expansion; incubation period and latency period. Data were submitted to analysis of variance, Pearson correlation and multivariate analysis based on Mahalanobis distance, using the Tocher and UPGMA clustering method. Significant differences were observed in the level of (p<0.01) and (p<0.05), for almost all variables analyzed. Of the 45 correlations, only...
