Adaptation of fluorescent technique for genotyping with new microsatellite markers in common bean.

The objectives of this work were to adapt the fluorescent labeling ( PCR) technique using M13 universal primer for genotyping purposes, and to present a new set of microsatellite markers for common bean ( Phaseolus vulgaris L.). A large population (380 common bean lines) was used for microsatellite genotyping. PCR fluorescent labeling method showed to be very efficient for multiplex analysis, providing lower costs and saving time, thus increasing the quality of genotyping analysis. A new set of 50 microsatellites developed from an enriched library derived from cultivar IAC-UNA was presented. This study provides better tools for assisting common bean breeding programs.
