Beans Genotypes (Phaseolus vulgaris L.) of the Black Group in the Cerrado Environment, Brazil

Abstract

Beans are considered one of the most economically important agricultural crops in Brazil. However, the country is not yet self-sufficient in this crop, importing still about 10% of the beans consumed. The objective of this study was to evaluate the performance of seven black bean cultivars under the soil and climatic conditions of the Brazilian cerrado. The experiment was carried out under a randomized block design, with three replicates. Seven cultivars of black beans were tested: i) BRS Campeiro, ii) BRS 7762 Supremo, iii) BRS Esplendor iv) CNFP 10104, v) CNFP 10793, vi) CNFP 10794 and vii) CNFP 10806). Plant architecture, planting, number of days to flowering and number of days to harvest, as well as the final population of plants, grain yield per plant, yield and weight of 100 grains were evaluated. The varieties tested did not present significant differences in relation to the architecture and the lodging degree. In addition, the number of days to flowering, as well as the number of days to harvest, had little variation among the tested cultivars. However, cultivars CNFP 10104 and CNFP 10793, although they did not show a significant statistical difference compared to the other cultivars in relation to the final population of plants and production per plant, presented the highest yields (kg ha-1) and also the highest values for the Weight of 100 grains. It is concluded that the cultivars CNFP 10104 and CNFP 10793 are those with the greatest potential for use in the soil and climatic conditions of the cerrado of Brazil.
