ABSTRACT The lack of records about snap bean cultivars is one of the obstacles that has led to a yield gap and low prominence of the crop. This work aimed at indicating snap bean lines obtained by the Breeding Program of the Universidade Estadual do Norte Fluminense (UENF) to assess their performance and to apply for a certificate of plant variety protection. The study was managed using a randomized block design with three replicates in a greenhouse at the Research Support Unit of the UENF. Nine candidate lines were compared to the commercial cultivar “Topseed Blue Line” in accordance with 56 descriptors set by the National Plant Variety Rights. All lines presented themselves as homogeneous. The L31 line provided a total of 30 different descriptors of the commercial cultivar. For the quantitative data added to the Distinctness, Uniformity and Stability, (DUS) tests, the analysis of variance was performed and the GT biplot generated by the R software. Variability was noticed among the genotypes for all assessed traits, excepting days until germination and seed thickness. The lines that showed the best mean performance were L6, L7, L10, L11, and L13. Among those, the L6 and L11 lines provided higher stability.
