Feed efficiency is jointly determined by productivity and feed requirements, both of which are economically relevant traits in beef cattle production systems. The objective of this study was to identify genes/ QTLs associated with components of feed efficiency in Nelore cattle using Illumina BovineHD BeadChip (770 k SNP) genotypes from 593 Nelore steers. The traits analyzed included: average daily gain (ADG), dry matter intake (DMI), feed-conversion ratio (FCR), feed efficiency (FE), residual feed intake (RFI), maintenance efficiency (ME), efficiency of gain (EG), partial efficiency of growth (PEG) and relative growth rate (RGR). The Bayes B analysis was completed with Gensel software parameterized to fit fewer markers than animals. Genomic windows containing all the SNP loci in each 1 Mb that accounted for more than 1.0% of genetic variance were considered as QTL region. Candidate genes within windows that explained more than 1% of genetic variance were selected by putative function based on DAVID and Gene Ontology. |

Butternut pumpkin is a cucurbit species of great economic and social importance for the Northeastern Region of Brazil. About 500 accessions are maintained in the Active Germplasm Bank of Embrapa Tropical Semiarid. This great potential for agricultural production has stimulated research on the characterization and study of the species? divergence, with a view to identify promising preserved accessions for breeding programs. The purpose of this study was to detect similarity groups among the 73 C. moschata accessions from the above-mentioned Cucurbit Germplasm Bank. Seed descriptors were used to observe the relationship between collection site and formation of divergent groups. Twenty-four seeds per accession and six multicategorical descriptors were used to generate a Jaccard similarity matrix and an UPGMA dendrogram. The formation of two major groups with four subgroups each, with a minimum phenotypic similarity of 31.5 and 35.8%, respectively, was observed. In conclusion, wide variability and no relationship between site collection and phenotypic similarity were observed among the accessions. |
