In the selection process of common bean genotypes with high yield performance associated with high adaptability and stability, accurate statistical procedures should be used, which promote greater precision in the comparison of means. In this context, the study aimed to select black bean genotypes of a normal and early cycle that simultaneously combine high yield, adaptability, and stability via nonparametric methods and mixed models. For this, two simultaneous trials were conducted in 2020 and 2021 in Campos dos Goytacazes-RJ. The first trial consisted of 14 black bean genotypes of the normal cycle; the second trial consisted of 14 black bean genotypes of the early cycle. The experimental design was a randomized block design with 14 normal-cycle and 14 early-cycle genotypes and three replications. After detecting the significant genotype-environment interaction (GxE), the adaptability and phenotypic stability of the genotypes were analyzed by the methods of the harmonic mean of the relative performance of genotypic values (HMRPGV), Annicchiarico (J Genet Breed 46:269–269, 1992), Lin and Binns (Can J Plant Sci 68(1):193–198, 1988), and stability index called WAASB (Weighted Average of Absolute Scores). The genotypes that gather adaptability and stability associated with high yield potential, sufficient for a recommendation for the state of Rio de Janeiro, are BRS FP403, BRS Esteio, CNFP 19325 belonging to the normal group and BRS Campeiro, CNFP 17445, and CNFP 17466 belonging to the early group. Therefore, the joint use of estimates of predicted genetic gain and estimates of adaptability and stability (MHPRVG) via mixed models, as well as estimates of stability and adaptability parameters according to the methodology of Annicchiarico (J Genet Breed 46:269–269, 1992), Lin and Binns (Can J Plant Sci 68(1):193–198, 1988), modified by Carneiro et al. (Novas metodologias de análise da adaptabilidade e estabilidade de comportamento, Doctoral dissertation, Universidade Federal de Viçosa, 1998), as well as the average performance and stability of genotypes using WAASB enabled the selection and more accurate indication of the most promising genotypes described above.
