Abstract Background There is a need for better evidence for the impact of plant breeding research on nutrient-rich crops such as pulses to guide policy-making and investment. Mungbean (Vigna radiata (L). Wilczek) is one of the major pulses of South and Southeast Asia and makes an important contribution to food security and agricultural sustainability. The objective of this study is to quantify impact of and returns on investment from international mungbean breeding research for Myanmar.
