HIOLANDA, Rosivaldo et al. Performance of carioca bean genotypes in Central Savannah's Brazil. Rev. de Ciências Agrárias [online]. 2018, vol.41, n.3, pp.241-250. ISSN 0871-018X.  https://doi.org/10.19084/RCA17285.

The common bean is cultivated by small, medium and large producers in different regions of the world and times of cultivation, being the time of the drought (2nd harvest) more appreciated by the farmers. The objective of this study was to evaluate the performance and productivity of carioca beans in Cerrado of Campo Novo do Parecis, Mato Grosso, Brazil. The study was conducted in two years, between February and May 2016 and 2017, in the experimental area of ​​the Federal Institute of Education, Science and Technology of Mato Grosso - IFMT. The experimental design was in randomized blocks, with twenty treatments (genotypes) and three replications. Data were submitted to analysis of variance and the Scott-Knott mean test at 5% probability. For the vegetative characteristics plant height and stem diameter, when observed to the adaptation to the mechanical harvest (height > 40 cm) and absence of lodging, standard genotypes and the lines stand out. In terms of precocity, all genotypes are suitable for cultivation in the Central’s Brazil. The genotypes CNFC 15805, CNFC 15820, CNFC 15743, CNFC 15801 and CNFC 15853 showed higher yield potentials (above 460 kg ha^-1) to the others (including the standard genotypes), whose yields were below 443 kg ha^-1, which are statistically the same.
