The common bean (Phaseolus vulgaris L.) is the main source of vegetable protein in the human diet and due to its nutritional characteristics, it is a legume of great importance worldwide. With the advance of technology and the fall in the cost of new generation sequencing (NGS), obtaining genotypic data such as SNPs is becoming more and more accessible. The main "bottleneck" today is the exploitation of the large amount of data obtained, so that the investment for genotyping can be fully utilized. Genome wide association studies (GWAS) allow the identification of loci that influence the expression mainly of quantitative characteristics. In this context, the current project aims to identify QTLs/genes associated with color control, brightness and darkening of the grain, flowering cycle, maturation and protein content. For this reason, a set of 5,679 GBS genotyped SNPs will be used in a population composed of 91 backcrossing inbred lines and 6,000 SNPs genotyped via BeadChip in a core collection composed of 288 accessions from the Agronomic Institute of Campinas (IAC), in a total of 379 Brazilian accessions with 11,679 SNPs. The work will allow the integration of the genotypic data of the Brazilian accessions to the BEAN_ADAPT project, contributing significantly to the understanding of evolution, genetic diversity and population structure, making possible the application of the results in future programs of common bean breeding in the world.
