Summary: | Popcorn is a special type of corn and approximately a thousand of landraces are conserved in situ in rural properties (on farm) from the Western Santa Catarina (WSC). The characterization is fundamental to promote their conservation, valorization and commercial use. This study aimed at characterizing ten popcorn landraces from this region. Thus, the varieties were evaluated in Florianópolis-SC, in a complete randomized block design with four repetitions and useful plot of 4m². Morphological characteristics of plants, ears, kernels and cycle of the varieties were evaluated according to descriptors of Zea mays L. The popcorn varieties from WSC showed diversity for phenological, morphological and agronomic characteristics. Two varieties were classified as extra early, three were early, one intermediate and four were late. The varieties 880A, 977A, 574A, 2312A and 2489D were highlighted as genetic sources for important characteristics in the development of new cultivars, such as plant height, productive potential and circularity index. |

A caracterização destas variedades é fundamental para a promoção da sua conservação, valorização e uso comercial. O objetivo deste estudo foi caracterizar a diversidade fenotípica de dez variedades locais de milho pipoca desta região. Para tanto, as variedades foram avaliadas em Florianópolis/SC, em blocos completos casualizados com quatro repetições e parcela útil de 4m². As características morfológicas de planta, espiga e grão e o ciclo das variedades foram avaliados de acordo com os descritores de Zea mays L. As variedades de milho pipoca do EOSC apresentaram diversidade para caracteres fenológicos, morfológicos e agronômicos. Duas variedades foram classificadas como hiperprecoces, três precoces, uma intermediárias e quatro tardias. As variedades 880A, 977A, 574A, 2312A e 2489D se destacaram como fontes genéticas de características importantes para o desenvolvimento de novos cultivares, tais como altura de planta, potencial produtivo e índice de circularidade.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2019-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/36410.22491/RAC.2019.v32n3.7Agropecuária Catarinense Journal; Vol. 32 No. 3 (2019); 56-61Agropecuária Catarinense; v. 32 n. 3 (2019); 56-612525-60760103-0779reponame: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/364/450Copyright (c) 2019 Revista Agropecuária Catarinenseinfo:eu-repo/semantics/openAccessSeledes, Rose MariOgliari, Juliana BernardiMelhorança, Estêvão Augusto LombertiSouza, Rosenilda dedos Santos Oliveira, Wagner Bastos2020-04-28T21:40:08Zoai:ojs.publicacoes.epagri.sc.gov.br:article/364Revistahttps://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:2020-04-28T21:40:08Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false |
