Resumo: High grain yield and good quality are the main objectives of rice breeding program of Epagri. Twobreeding methods are used, namely crosses between two or more cultivars, and induced mutations. The latter allows the generation of genetic variability from a single cultivar. Rice cultivar SCS 114 Andosan was obtained through gamma rays irradiation of seeds from the parent cultivar IR 841. IR 841 was one of the first dwarf type and highly productive cultivars used in Santa Catarina, due to its high grain yielding potencial; however, its grain quality is poor. As the rice grown area expanded, IR 841 became susceptible to blast. The selected mutant SCS 114Andosan is as productive as the original cultivar and has also shown higher resistance to blast and superior grain quality.

Na Epagri, o melhoramento de arroz irrigado visa o desenvolvimento de cultivares produtivas, alto rendimento industrial e adequadas propriedades culinárias. Dois métodos mais utilizados são a hibridação controlada entre duas ou mais cultivares e a mutação induzida, que permite criar variabilidade a partir de uma única cultivar. A cultivar SCS 114 Andosan foi desenvolvida através da irradiação com raios gama sobre as sementes da cultivar IR 841. Esta cultivar foi uma das primeiras do tipo moderno cultivadas em Santa Catarina, cuja característica principal era o seu alto potencial produtivo. Entretanto, após alguns anos, tornou-se suscetível àbrusone, além de apresentar baixa qualidade de grãos. A mutante obtida SCS 114 Andosan mostra-se tão produtiva como a variedade original, além de apresentar maior resistência à brusone e qualidade de grãos bem superioresà variedade IR 841.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2021-06-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/986Agropecuária Catarinense Journal; Vol. 18 No. 3 (2005); 87-90Agropecuária Catarinense; v. 18 n. 3 (2005); 87-902525-60760103-0779reponame: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/986/883Copyright (c) 2005 Agropecuaria catarinensehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessIshiy, TakaziSchiocchet, Moacir Antonio Bacha, Richard Elias Morel, Dario Alfonso Ando, Akihiko Tulmann Neto, Augusto Knoblauch, Ronaldir 2021-06-23T14:20:52Zoai:ojs.publicacoes.epagri.sc.gov.br:article/986Revistahttps://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:2021-06-23T14:20:52Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
