The present work has aimed to assess the consideration of the appropriate variation sources of the statistical model and their impacts on the conclusions plant breeding. The Value for Cultivation and Use test was conducted to assess three common locations (Lages, Ponte Serrada, and Canoinhas) and four non-common locations (Chapecó, Guatambu, Urussanga, and Campos Novos). The grain yields of six bean genotypes were evaluated in order to represent the imbalance between the common and non-common locations. The statistical analysis considered two situations: i) union of the location factors and cultivation years, with a single variation source called environment and ii) decomposition of the mean square values of the two factors, location and year. According to... |

Selection for grain yield, combined with phenological and morphological characteristics of agricultural interest, represents technological advances in the common bean. The objectives of this work were to estimate genetic parameters and the efficiency of both the Pedigree and Single-Seed Descent (SSD) methods for progression segregating populations in order to obtain common bean lines superior in grain yield, precocity and plant architecture. To do this, 136 inbred lines obtained using the Pedigree method, and 136 inbred lines obtained by SSD method were evaluated in a 17 x 17 simple lattice design, integrating the 272 inbred lines in the F7 generation and 17 cultivars as control. Estimates of moderate narrow sense heritability were obtained for grain... |
