ZANELLA, Rodrigo et al. Performance of common bean genotypes as a function of growing seasons and technological input levels1. Pesqui. Agropecu. Trop. [online]. 2019, vol.49, e54989.  Epub Sep 26, 2019. ISSN 1517-6398.

In Brazil, common bean (Phaseolus vulgaris L.) is cultivated in different growing seasons and environments, with different genotypes responses due to the genotype x environment interaction. This study aimed to identify common bean genotypes with a better production stability in each growing environment. The trials were conducted in a randomized block design, with three replications, involving three growing years, nine common bean genotypes and four environments (first and second growing seasons with high and low levels of technological input, such as fertilizers and pest and disease control). Biplot analyses were performed using the GGE Biplot software. The use of high levels of technological input results in an average increase of 14.4 % for yield and is more representative in the crop environments, as well as more adequate for genotype selection. IPR Campos Gerais, BRS Esplendor and BRS Campeiro showed a high stability and presented the best productive performance under both technological levels.

Keywords : Phaseolus vulgaris L.; genotype x environment interaction; grain yield.
