Resumo: | The objective of this work was to evaluate the agronomic traits of sunflower hybrids adapted to second crop and to determine the correlations between them. Fifteen hybrids were tested – two high-oleic and 13 non high-oleic ones (traditional hybrids) –, besides one hybrid used as a check. A randomized complete block experimental design was carried out with four replicates, and sowings were done in 2013 and 2014. The evaluated traits were the following: days to physiological maturity, plant height, grain yield, oil content, and oil yield. The higher grain yields occurred in hybrids that are neither of early cycles nor of shorter stems. The correlation between grain yield and oil yield was positive and significant; however, the correlations between oil content and these two traits were not significant. The 'Syn 045' and 'Syn 3950A' sunflower hybrids (high-oleic) stood out, in the second season, both for grain yield and oil yield. The 'CF 101' hybrid – early cycle – shows good grain and oil yield, and, therefore, it is an appropriate option for late sowing in the second season. Thus, adapted sunflower hybrids with appropriate traits are available for second season cropping and to meet market demands. |

Testaram-se 15 híbridos – dois alto oleicos e 13 não alto oleicos (híbridos tradicionais) –, além de um híbrido como testemunha. Um delineamento experimental de blocos ao acaso foi utilizado com quatro repetições, e as semeaduras foram feitas em 2013 e 2014. As características avaliadas foram as seguintes: dias para a maturação fisiológica, altura de planta, produtividade de grãos, teor de óleo e produtividade de óleo. As maiores produtividades de grãos ocorreram em híbridos que não são nem precoces nem de porte mais baixo. A correlação entre produtividade de grãos e produtividade de óleo foi positiva e significativa; no entanto, as correlações entre teor de óleo e essas duas características não foram significativas. Os híbridos de girassol 'Syn 045' e 'Syn 3950A' (alto oleico) se destacaram, na segunda safra, quanto à produtividade de grãos e de óleo. O híbrido 'CF 101' – ciclo precoce – apresenta boa produtividade de grãos e de óleo e, portanto, é a opção adequada para a semeadura tardia na segunda safra. Assim, estão disponíveis híbridos de girassol adaptados e com características adequadas ao cultivo de segunda safra e às demandas do mercado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraDalchiavon, Flávio CarlosCarvalho, Claudio Guilherme Portela deAmabile, Renato FernandoGodinho, Vicente de Paulo CamposRamos, Nilza PatríciaAnselmo, Jefferson Luís2016-12-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/23737Pesquisa Agropecuaria Brasileira; v.51, n.11, nov. 2016; 1806-1812Pesquisa Agropecuária Brasileira; v.51, n.11, nov. 2016; 1806-18121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/23737/13627https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/23737/15673Direitos autorais 2016 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2016-12-23T12:32:40Zoai:ojs.seer.sct.embrapa.br:article/23737Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2016-12-23T12:32:40Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
