Summary: | The far west region of Santa Catarina (FWSC) state in southern Brazil was indicated as a microcenter of diversity of the Zea genus. In this region, local popcorn varieties are grown in small areas, but in a significant number of farms. The present study aimed to characterize the diversity of 41 local populations from that region, based on phenology and morphological characters of plant, ear and grain. Therefore, an experimental design of complete randomized blocks with two replications was conducted. The data allowed to identify a rich diversity of popcorn in the FWSC for the characteristics of plant, ear, and grain, as well as for the phenology. For the color, 20 populations presented white grain, nine black, nine yellow, two red and one orange. Regarding the cycle, all varieties of yellow and round grains were considered hyper early/early and the varieties of white grains, intermediate/late. Average plant height varied from 1.8 to 3.2 m, while the weight of one thousand kernels varied from 80.9 to 200.4 g. The accumulated day degrees for tasseling ranged from 689.05 to 1,090.57. Based on the cluster analysis of qualitative and quantitative characters, three groups were formed, and five populations were isolated. The inclusion of plant characteristics and phenology can be an important and complementary tool for studies in popcorn races. Trends in some plant characteristics were observed within popcorn varieties with the same grain features. This result is important information for popcorn genetic breeding strategies. |

En esta región, las variedades locales de maíz reventón se cultivan en áreas pequeñas, pero en un número significativo de propiedades. El presente estudio tuvo como objetivo caracterizar la diversidad de 41 poblaciones locales de este tipo de maíz de esa región, con base en la fenología y caracteres morfológicos de planta, mazorca y grano. Por lo tanto, se realizó un diseño experimental de bloques completos al azar con dos repeticiones. Los datos permitieron identificar una rica diversidad de maíz reventón en el EOSC por las características de planta, mazorca y grano, así como para la fenología. Para el color, 20 poblaciones presentaron grano blanco, nueve negros, nueve amarillos, dos rojos y uno naranja. En cuanto al ciclo, todas las variedades de granos amarillos y redondos se consideraron muy precoces/tempranas y las variedades de granos blancos, intermedias/tardías. La altura promedio de las plantas varió de 1,8 a 3,2 m, mientras que el peso de mil granos varió de 80,9 a 200,4 g. Los grados acumulados por día para la emisión de la espiga vario entre 689,05 y 1.090,57. Con base en el análisis de conglomerados de caracteres cualitativos y cuantitativos, se formaron tres grupos y se aislaron cinco poblaciones. La inclusión de las características de las plantas y la fenología puede ser una herramienta importante y complementaria para el estudio de las razas de maíz reventón. En algunas características se observaron tendencias de las plantas dentro de las variedades con la misma característica de grano. Este resultado es importante para el mejoramiento genético de este tipo de maíz.A região do Extremo Oeste de Santa Catarina (EOSC), no sul do Brasil, foi indicada como um microcentro de diversidade do gênero Zea. Nesta região, as variedades locais de pipoca são cultivadas em pequenas áreas, mas em um número significativo de propriedades. O presente estudo teve como objetivo caracterizar 41 populações locais de milho pipoca dessa região, com base em descritores fenológicos e morfológicos associados à planta, espiga e ao grão. Para tanto, foi realizado um experimento no delineamento de blocos completos casualizados com duas repetições. Os dados permitiram identificar uma rica diversidade de milho pipoca no EOSC para as características de planta, espiga e grão, bem como para a fenologia. Quanto à cor, 20 populações apresentaram grãos brancos, nove pretos, nove amarelos, duas vermelhos e uma alaranjado. Quanto ao ciclo, todas as variedades de grãos amarelos e redondos foram consideradas hiperprecoces/precoces e as variedades de grãos brancos foram intermediárias/tardias. A altura média de planta variou de 1,8 a 3,2 m, enquanto o peso de mil grãos variou de 80,9 a 200,4 g. O acúmulo de graus dia para o pendoamento variou de 689,05 a 1.090,57. Segundo a análise de agrupamento de caracteres qualitativos e quantitativos, três grupos foram formados e cinco populações ficaram isoladas. A inclusão de características de planta e fenologia pode ser uma ferramenta importante e complementar aos estudos de raças de milho pipoca. Tendências em alguns caracteres de planta foram observadas em variedades de milho pipoca com a mesma característica de grão. Este resultado é importante para a definição de estratégias de melhoramento genético dessa cultura.Research, Society and Development2021-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1673410.33448/rsd-v10i7.16734Research, Society and Development; Vol. 10 No. 7; e46710716734Research, Society and Development; Vol. 10 Núm. 7; e46710716734Research, Society and Development; v. 10 n. 7; e467107167342525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/16734/15034Copyright (c) 2021 Francisco Wilson Reichert Júnior; Juliana Bernardi Ogliari; Otávio Rechsteiner Maghelly; Rosenilda de Souzahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessReichert Júnior, Francisco Wilson Ogliari, Juliana BernardiMaghelly, Otávio RechsteinerSouza, Rosenilda de2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/16734Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:12.794213Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
