The common bean (Phaseolus vulgaris L.) is a crop of great importance in Cuba, but it is necessary to implement strategies to increase its yields, since production is well below national demand. The selection of varieties adapted to the product context plays an important role. The objective of this work was to evaluate the yield, the adaptability between seasons and the peasant acceptance of red bean ‘Odile’ new cultivar. Four experiments were carried out in the period between September 2015 and April 2017 in two areas, farm “El Mulato” and the experimental area of the National Institute of Agricultural Sciences (INCA), where five commercial varieties were included. In turn, in September 2015, January 2016 and November 2017, the cultivar ‘Odile’ was sown in experimental plots with other experimental lines and commercial varieties, to carry out the participatory selection carried out by farmers. The analysis of variance of the yield and the reaction to diseases indicated that the cultivar 'Odile' showed yields higher than 2000 kg ha-1 and resistance to common bacteriosis, BGYMV and rust, as well as an interaction between planting seasons. The AMMI analysis showed the stability of the cultivar 'Odile' yield and the analysis of proportions showed that black beans are more accepted by farmers, but cultivar 'Odile' showed high peasant acceptance with percentages higher than 96 %.
