Resumo: | The objective this work was to verifield efficience of repetibility methods in the genotypes sugarcane selection on final stages of experimentation. The experiment was conducted in randomized block design with four repetitions. Were evaluated sixteen genotypes in four harvest cycles. The caracters analyzed were POL tonnage per hectare, sugarcane tonnage per hectare and total recoverable sugar tonnage per hectare. Were used four methodologies for repetibility analyses: variance analyse, principal components, estructural analyse and mixed linears models. The genotypes RB96972616 and RB972631 showed hight productivity, hight genetics valours predicteds and showed high genetic means free from interactions. By the variance analyse methods, of the principal components and estructural analyse three assessments would be necessary to select genotypes with 80% of predictability of the your real valours. The mixed models methodology, showed more efficient because besides to identified genotypes with genotipic stability in the harvest cycles, revealed that, through a 90% accuracy, two evaluations are enough to selected genotypes with high regrowth capacity, in the final stages of experimentation. |

El experimento fue diseñado en bloques aleatorios con 4 repeticiones. Se evaluaron 16 genotipos en cuatro ciclos de cosecha, los caracteres evaluados fueron: toneladas de pol por hectárea, toneladas de caña por hectárea y toneladas de azúcares recuperables totales por hectárea. Se utilizaron cuatro metodologías para el análisis de repetibilidad: análisis de varianza, componentes principales, análisis estructural y modelos lineales mixtos. Los genotipos RB972616 y RB972631 se destacaron en términos de productividad, predijeron valores genéticos y tuvieron mayores medios genotípicos libres de interacciones. Mediante el método de análisis de varianza, componentes principales y análisis estructural, serían necesarias tres evaluaciones para la selección de genotipos, en las etapas finales de experimentación, con una previsibilidad del 80% de sus valores reales. La metodología del modelo mixto, por otro lado, demostró ser más eficiente, porque además de identificar genotipos con estabilidad genotípica a lo largo de los ciclos de cosecha, reveló que, con una precisión del 90%, dos evaluaciones son suficientes para la selección de genotipos con alta capacidad de rebrote, en las etapas finales de experimentación.O presente trabalho teve por objetivo, verificar a eficiência de diferentes métodos de repetibilidade na seleção de genótipos de cana-de-açúcar, com maior capacidade de rebrota, nas fases finais de experimentação. O experimento foi delineado em blocos ao acaso com 4 repetições. Foram avaliados 16 genótipos em quatro ciclos de colheita, os caracteres avaliados foram: toneladas de pol por hectare, toneladas de cana por hectare e toneladas de açúcares totais recuperáveis por hectare. Utilizou-se quatro metodologias para análise de repetibilidade: análise de variância, componentes principais, análise estrutural e modelos lineares mistos. Os genótipos RB972616 e RB972631 se destacaram quanto a produtividade, valores genéticos preditos e apresentaram maiores médias genotípicas livres das interações. Pelo método da análise de variância, de componentes principais e da análise estrutural, três avaliações seriam necessárias para a seleção de genótipos, nas fases finais de experimentação, com previsibilidade de 80% de seus valores reais. Já a metodologia de modelos mistos, mostrou-se mais eficiente, pois além de identificar genótipos com estabilidade genotípica ao longo dos ciclos de colheita, revelou que, por meio de uma acurácia de 90%, duas avaliações se mostram suficientes, para a seleção de genótipos com alta capacidade de rebrota, nas fases finais de experimentação.Research, Society and Development2020-08-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/724610.33448/rsd-v9i9.7246Research, Society and Development; Vol. 9 No. 9; e174997246Research, Society and Development; Vol. 9 Núm. 9; e174997246Research, Society and Development; v. 9 n. 9; e1749972462525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/7246/6616Copyright (c) 2020 João de Andrade Dutra Filho; Tercilio Calsa Júnior; Djalma Euzébio Simões Neto; Lauter Silva Souto; Rômulo Gil de Luna; Anielson dos Santos Souzahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDutra Filho, João de Andrade Calsa Júnior, TercilioSimões Neto, Djalma EuzébioSouto, Lauter SilvaLuna, Rômulo Gil deSouza, Anielson dos Santos2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/7246Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:02.129856Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
