Can Hybrid Rice Technology Help Productivity Growth in Asian Tropics?

The 1990s witnessed a significant deceleration in growth of rice productivity. The productivity potential of the existing modern rice varieties is getting exhausted especially under irrigated environments. This raises a serious concern about Asia's ability to sustain its food security in the 21st century. To find solutions to reverse this trend in irrigated systems, and raise yield levels in rain-fed areas, many public sector R and D institutions across Asia have invested huge public resources to explore new frontiers of rice science. However, many farmers, who grew hybrid rice initially, have started dropping out from hybrid rice cultivation. Can the currently available hybrid rice technology sustain productivity growth in the Asian tropics? Why has it not been possible to replicate in the Asian tropics China's success with hybrid rice? The paper provides a synthesis of major findings of a multi-country evaluation of farmers' experiences with the adoption of hybrid rice varieties.
