Abstract: Common beans (Phaseolus vulgaris L.) are vital for food security and rural livelihoods in Central America and Haiti. Over the past 30 years, R&D has focused on breeding resilient bean varieties to withstand climate change, pests, and diseases. However, the success of these innovations depends not only on variety development but also on efficient seed systems that deliver them to farmers—a crucial yet often overlooked factor in maximizing agricultural R&D benefits.
