Genetic progress estimation strategy for upright common bean plants using recurrent selection. Repositório Alice
PEREIRA, L. A.; ABREU, A. F. B.; VIEIRA JÚNIOR, I. C.; PIRES, L. P. M.; RAMALHO, M. A. P..
Common bean producers in Brazil tend to grow plants as upright as possible. Because the control of this trait involves a large number of genes, recurrent selection (RS) is the best approach for successful plant improvement. Because plant architecture (PA) is evaluated using scores and usually has high heritability, RS for PA is performed through visual selection in generation S0. The aim of the present study was to evaluate selection progress and investigate whether this progress varies with the number of selected progenies or the generation evaluated. In addition, the effect of RS for the upright (PA) trait on progeny grain yield (GY) was investigated. Data of progenies S0:3 and S0:4 of the fifth, eighth, and twelfth cycles were used. A combined analysis...
