Agronomic characterization of high-yielding irrigated barley accessions in the Cerrado
Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: Sayd,Ricardo Meneses; Amabile,Renato Fernando; Faleiro,Fábio Gelape; Montalvão,Ana Paula Leite; Coelho,Mateus Costa.
Abstract: The objective of this work was to estimate the genetic, phenotypic, and environmental parameters of 113 barley accessions (Hordeum vulgare), previously selected based on high yield, in an irrigated production system in the Cerrado (Brazilian savanna), for use in breeding programs in Brazil. The experiment was conducted in 2013 at two sites in the Federal District, using a randomized complete block design with three replicates. The evaluated traits were: grain yield, kernel plumpness, thousand grain weight, plant height, lodging, and days to heading. Significant differences were observed between environment and accessions for all studied traits, as well as genotype x environment interaction. The MCU 3832 PI 402310, MCU 3484 PI 401962, CI 08053...

Genetic variability in conilon coffee related to grain attributes in an irrigated crop in the Cerrado
Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: Brige,Felipe Augusto Alves; Celestino,Sonia Maria Costa; Amabile,Renato Fernando; Fagioli,Marcelo; Delvico,Francisco Marcos dos Santos; Montalvão,Ana Paula Leite; Sala,Pedro Ivo Aquino Leite.
Abstract: The objective of this work was to quantify the genetic variability of 213 conilon coffee accessions of the Robusta Tropical cultivar, based on chemical characteristics related to the quality of green coffee beans, as well as to identify promising accessions for the breeding program of irrigated conilon coffee in the Brazilian Cerrado. The chemical characteristics evaluated were: protein and caffeine contents, total soluble solids and total lipids, ether extract, pH, and total titratable acidity. The data were subjected to the principal component analysis and cluster analysis based on the similarities observed within the first two principal components using the minimum variance method (Wards) and, as a measure of similarity, the Euclidean...

Genetic parameters, phenotypic, genotypic and environmental correlations and genetic variability on sunflower in the Brazilian Savannah
Provedor de dados: Ciência Rural
Autores: Lira,Ellen Grippi; Amabile,Renato Fernando; Fagioli,Marcelo; Montalvão,Ana Paula Leite.
ABSTRACT: Sunflower (Helianthus annuus L.) is an annual crop that stands out for its production of high quality oil and for an efficient selection, being necessary to estimate the components of genetic and phenotypic variance. This study aimed to estimate genetic parameters, phenotypic, genotypic and environmental correlations and genetic variability on sunflower in the Brazilian Savannah, evaluating the characters grain yield (YIELD), days to start flowering (DFL) based on flowering date in R5, chapter length (CL), weight of a thousand achenes (WTA), plant height (H) and oil content (OilC) of 16 sunflower genotypes. The experiment was conducted at Embrapa Cerrados, Planaltina, DF, situated at 15º 35’ 30”S latitude, 47º 42’ 30”W longitude and 1.007m above...
