Resumo: The annual ryegrass is widely used in pastoral systems in southern Brazil because it is cold-resistant, productive, vigorous, high nutritional forage, being recommended to compose the diet of cattle and sheep with greater nutritional demand as it provides high gains in animal production. The various commercially available ryegrass cultivars can be divided into annual ryegrass (diploids or tetraploids) westerwoldico variety (Lolium multiflorum Lam. var. westerwoldicum) and italic ryegrass variety (L. multiflorum Lam. var. italicum). Originally, annual ryegrass is diploid (2n), but after natural hybridization and/or genetic improvement, several tetraploid (4n) cultivars were developed and made available. The differences between them include leaf/stem ratio, size of leaves and tillers, number of tillers, initial vigor, dry matter production, nutritional quality, drought resistance, length of the productive cycle, among other characteristics. Although, the variety and ploidy level are insufficient to determine the superiority of one material over another and, when deciding which seed to acquire, the particular characteristics of each cultivar and the pastoral system where it will be used must be carefully observed. The aim of this study was to gather information about the annual ryegrass and some of the cultivars commercialized in the State of Santa Catarina, Brazil.

Os vários cultivares de azevém-anual comercialmente disponíveis podem ser divididos em azevém-anual (diploides ou tetraploides) variedade westerwoldicum (Lolium multiflorum Lam. var. westerwoldicum) e azevém-anual variedade itálico (L. multiflorum Lam. var. italicum). Originalmente, o azevém-anual é diploide (2n), mas após hibridização natural e/ou melhoramento genético vários cultivares tetraploides (4n) foram desenvolvidos e disponibilizados. As diferenças entre eles incluem relação folha/colmo, tamanho de folhas, perfilhos e sementes, número de perfilhos, vigor inicial, produção de matéria seca, qualidade nutricional, resistência à seca, duração do ciclo produtivo, entre outras características. Mas a variedade e o nível de ploidia são insuficientes para determinar superioridade de um material sobre outro e, no momento de decidir qual semente adquirir, devem ser observadas cuidadosamente as características particulares de cada cultivar e do sistema pastoril onde será utilizado. O objetivo deste estudo foi reunir informações sobre o azevém-anual e alguns dos cultivares comercializados no estado de Santa Catarina, Brasil.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2022-04-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/130610.52945/rac.v35i1.1306Agropecuária Catarinense Journal; Vol. 35 No. 1 (2022); 85-92Agropecuária Catarinense; v. 35 n. 1 (2022); 85-922525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1306/1304Copyright (c) 2022 Ângela Fonseca Rech, Ulisses Cordoba, Vanessa Fávaro, Jefferson Flaressohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRech, Ângela FonsecaCordoba, Ulisses de ArrudaFávaro, Vanessa RuizFlaresso, Jefferson Araújo 2022-06-22T11:43:17Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1306Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2022-06-22T11:43:17Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
