Resumo: | Well-designed field experiments are able to deal with spatial variability, resulting in accurate and useful information. However, it is known that there are variations in the experimental areas, in addition to those indirectly induced by driving practices. In this sense, the aim of this paper was to decompose the causes of variation, making it possible to verify the effect of the genotype x block interaction and its implications, in the evaluation of grain yield in fixed and segregating bean genotypes. The experiment was conducted in the field crop in the 2020/21 senson in Lages - SC. The treatments were composed by the genotypes: i) IPR88 Uirapuru x BAF35, in the F2 generation; ii) IPR88 Uirapuru x BAF35, in the F5 generation; iii) IPR88 Uirapuru parent and iv) BAF35 parent; arranged in a randomized block experimental design with more than one repetition per block, with 3 blocks and 4 repetitions per treatment in each block. With the grain yield data (g plot-1), analysis of variance and decomposition of the causes of variation by orthogonal contrasts were performed. Analysis of variance showed significance for block, genotype and the genotype x block interaction (p<0.05). Similarly, the decomposition into genotypes within each block also revealed significance (p<0.05). In addition, the decomposition of the genotype variation in the different blocks showed a greater fraction of this sum of squares, present in only one block, being inherent mainly to the parents. Thus, the repletion use within the blocks made it possible to properly verify the spatial variation this the experiment, which is essential when applying the selection. |

Contudo, sabe-se que existe variações nas áreas experimentais, além das indiretamente induzidas por praticas de condução. Neste sentido, o objetivo do trabalho foi decompor as causas de variação, possibilitando verificar o efeito da interação genótipo x bloco e suas implicações, na avaliação do rendimento de grãos em genótipos fixos e segregantes de feijão. O experimento foi conduzido a campo na safra agrícola 2020/21 em Lages – SC. Os tratamentos foram compostos pelos genótipos: i) IPR88 Uirapuru x BAF35, na geração F2; ii) IPR88 Uirapuru x BAF35, na geração F5; iii) genitor IPR88 Uirapuru e iv) genitor BAF35; dispostos em delineamento experimental de blocos casualizados com mais de uma repetição por bloco, sendo 3 blocos e 4 repetições por tratamento em cada bloco. Com os dados do rendimento de grãos (g parcela-1), foi realizada a análise de variância e decomposição das causas de variação em contrates ortogonais. A análise de variância demonstrou significância para bloco, genótipo e a interação genótipo x bloco (p<0,05). Analogamente, a decomposição em genótipos dentro de cada bloco, também revelou significância (p<0,05). Além disso, a decomposição da variação de genótipos nos diferentes blocos, demonstrou uma maior fração da soma de quadrados presente em apenas um bloco, sendo inerente principalmente aos genitores. Com isso, o uso de repetições dentro dos blocos possibilitou uma verificação adequada da variação espacial do experimento, sendo essa fundamental no momento de realizar a seleção.Universidade Federal Rural da Amazônia/UFRA2024-01-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontextoapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/3590Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 66 (2023): RCA AJAES; 1-10Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 66 (2023): RCA AJAES; 1-102177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
