Conteúdo: |
Durante o ano agricola de 1975/76, estudou-se, em Vicosa, o comportamento de 60 variedades de mandioca, visando a producao de raizes e de ramas e teor de amido. Efetuou-se, ainda, um estudo de caracteristicas da parte aerea e das raizes das variedades. Paralelamente procuraram-se verificar algumas correlacoes entre producao de raizes e as variaveis producao de ramas, diametro do caule a 5 cm do solo, altura da planta, largura de ramificacao e altura de ramificacao. O ensaio foi instalado em um solo Podzolico Vermelho Amarelo Cambico, fase terraco, distrofico. Usou-se o delineamento de blocos ao acaso, com tratamentos comuns com 4 repeticoes. As variedades foram divididas em 3 grupos, de acordo com a altura observada antes da retirada da rama para plantio. |

In experiments with selection of perennial plants, the initial performance is expected to be maintained throughout the productive life. The probability of repeating the agronomic response can be evaluated by the repeatability coefficient. The objective was to estimate repeatability coefficients of agronomic characteristics in Panicum maximum Jacq. using different methods and identify the best combinations between harvests according to the genotypic stabilization. Seventeen genotypes were evaluated in a randomized complete block design with three replicates. The coefficients of repeatability were estimated by the methods: ANOVA, structural analysis based on the mean of the correlation coefficients (SACOR), analysis of principal components based on the covariance matrix (PCCOV) and correlation matrix (PCCOR). In the genotypic stabilization, coefficients estimated by ANOVA and PCCOR were used. For total DM, repeatability coefficients ranged from 0.3500 to 0.4300 by the ANOVA and PCCOR methods, respectively. High repeatability coefficients were found for the characteristic leaf DM, while low coefficients were observed for leaf and stem percentages and leaf:stem ratio. For the genotypic stabilization of total DM and leaf:stem ratio, the best coefficients were observed for the combination of harvests 5 to 8. There are variations in the estimate of repeatability by different methods and the highest coefficients were those of the principal components based on the correlation and covariance matrices. For the genotypic stabilization, the best coefficients of repeatability and determination were observed for the harvests performed in the second rainy period.
