Resumo: The objective of this work was to evaluate the relationship among phenotypic and quality traits in a set of indigenous and exotic accessions of linseed (Linum usitatissimum). The experimental material consisted of 151 accessions of linseed belonging to landraces and cultivars collected from diverse agroecological zones. Five randomly chosen plants of each accession in each replicate were tagged, and data were recorded for the 12 following agronomic traits: days to flowering, days to maturity, plant weight, plant height, tillers per plant, secondary branches per plant, capsules per plant, seeds per capsule, 1,000 seed weight, harvest index, seed yield per plant, and oil content. Capsules per plant, harvest index, and plant weight played a direct and indirect major role on seed yield. High heritability, coupled with high genetic advance for plant weight, secondary branches per plant, capsules per plant, and seed yield per plant, suggests that selection based on these traits can be effective. Regarding per se performance, the following accessions can be exploited for commercial cultivation: Shweta (5.41 g), Gaurav (5.07 g), and EX-3-3 (4.77 g) for seed yield; and Shubhra (45.09%), Mukta (44.94%), Laxmi-27 (45.06%), and Shweta (44.25%) for oil content. The chemical profiling of fatty acids obtained in the present study can provide a platform for the selection of accessions for the genetic improvement of linseed.

O material avaliado consistiu de 151 acessos de linhaça nativos ou de cultivares obtidas de diferentes zonas agroecológicas. Cinco plantas de cada acesso, selecionadas aletoriamente, foram identificadas, e foram registrados dados para as 12 seguintes características agronômicas: número de dias para o início do florescimento, número de dias para a maturação, peso da planta, altura da planta, número de perfilhos por planta, número de ramos secundários por planta, número de cápsulas por planta, número de sementes por cápsula, peso de mil grãos, índice de colheita, produção de sementes por planta e conteúdo de óleo. O número de cápsulas por planta, o índice de colheita e o peso da planta desempenharam papel importante tanto direta quanto indiretamente na produção de sementes. Altos valores de herdabilidade, associados a alto avanço genético para peso da planta, número de ramos secundários por planta, número de cápsulas por planta e produção de sementes por planta, sugerem que a seleção com base nestas características pode ser eficaz. Em relação ao desempenho per se, os seguintes acessos podem ser explorados em cultivo comercial: Shweta (5,41 g), Gaurav (5,07 g) e EX-3-3 (4,77 g) para produção de sementes; e Shubhra (45,09%), Mukta (44,94%), Laxmi-27 (45,06%) e Shweta (44,25%) para teor de óleo. O perfil químico dos ácidos graxos obtido no presente trabalho pode fornecer uma plataforma para a seleção de acessos para o melhoramento genético de sementes de linhaça.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLinum usitatissimum, correlaçãoácidos graxosavanços genéticosherdabilidadeanálise de trilhaSiddiqui, AmeenaShukla, SudhirRastogi, AnuBhargava, AtulNiranjan, AbhishekLehri, Alok2017-02-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/24033Pesquisa Agropecuaria Brasileira; v.51, n.12, dez. 2016; 1964-1972Pesquisa Agropecuária Brasileira; v.51, n.12, dez. 2016; 1964-19721678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/24033/13647https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/24033/15940Direitos autorais 2017 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2017-02-07T11:19:59Zoai:ojs.seer.sct.embrapa.br:article/24033Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2017-02-07T11:19:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
