The objective of this study was to evaluate some important agronomic traits for silage production of 12 hybrids and a variety of sunflower (Helianthus annuus L.) participant of the national assay of sunflower, in the agricultural year of 1996/97. The experiment was conducted from February to June 1997. The experimental procedure followed a randomized block design and the means values were compared by Student-Newman-Keuls test. Significant differences among hybrids for fresh and dry matter productions, leaf, head and stem percentages, stem's circumference close the head, broken plants percentage and height of the plants were observed. No significant differences among hybrids for stem's circumference close the ground, diameter of the head and laying plants percentage were found. The agronomic traits indicated that some hybrids of sunflower present potential to be used for silage production in double-cropping system, or during the drought. |

Accurate identification of species is fundamental to every biological research. While morphological identification is a time-consuming and skilled technique, straightforward molecular techniques require the availability of a database of previously sequenced and identified specimens. For most countries of South America, species of noctuids with available sequences are scarce, mostly restricted to species of economic importance, making molecular identification untenable. Here we sequenced the mitochondrial DNA ?barcode? region of the cytochrome c oxidase subunit I gene of 34 specimens pertaining to 26 species of South American noctuids, 20 of these for the first time. For all species, genetic distances were higher for interspecific than for intraspecific relations, supporting the utility of DNA ?barcodes? to identify species. Larger intraspecific divergences occurred in species of Agrotis and Anicla, and interspecific divergences lower than 2% occurred in about one fifth of the species, all in species of Agrotis, Feltia, and Anicla. These results will allow identifying these species using DNA ?barcodes?, either for pest management or general biological studies. Furthermore, we carried out phylogenetic analyses with those sequences and 158 other sequences of 85 species of noctuids mined from GenBank. These analyses, in every case, grouped species of the same genus suggesting that the DNA ?barcodes? region alone can be useful for lower level phylogeny in this group, recovering as monophyletic groups such as Copitarsia, Agrotis and Austrandesiita. Conversely, groups such as Mythimna (Mythimna) and the subgenera of Feltia were not recovered as monophyletic, suggesting the need for further taxonomic studies in these groups.
