| Descripción: | Introduction: The rescue of common bean landraces is of importance to preserve biodiversity, and to make use of this genetic base in plant breeding programs. There are few studies about this subject in Costa Rica. Objective: To characterize seeds of some common native beans in Guanacaste, Costa Rica. Methods: From April to August 2013, we collected seed samples of common bean (Phaseolus vulgaris) landraces (also called creole common beans) in Nicoya and Hojancha, through visits to local growers. We worked with Mantequilla, Nica, Revuelto, Sesenteno, Turrialba, and Vaina Blanca. Results: We found differences among varieties for quantitative variables, and a range of variation for weight of 100 seeds (17,16-26,52g), and for seed length (9,78-10,97mm), width (5,69-6,25mm), thickness (3,96-4,81mm), length/width ratio (1,69-1,84), length/thickness ratio (2,29-2,76), and width/thickness ratio (1,25-1,55). Conclusion: In Nicoya and Hojancha, there are significant variations among and within native bean seed landraces. |
