Rice is a staple food crop grown and consumed widely in India. A larger portion of rice acreage in India is still occupied by land race cultivars mostly cultivated by small and marginal farmers. This situation is more prevalent in upland rice farming. Upland farmers in Eastern India lacked high yielding rice variety with good quality and quantitative attributes and hence mostly cultivated poor yielding cultivars. In the late 1990s, a new approach known as Participatory Plant Breeding was adopted for breeding drought tolerant rice varieties suitable for upland cultivation in Eastern India. This was funded through Department For International Development (DFID), UK and implemented in collaboration with University of Wales at Bangor, UK in partnership with Gramin Vikas Trust (GVT), an NGO and Birsa Agricultural University (BAU). The research lead to the development of two upland rice varieties Ashoka 200F and Ashoka 228 and medium land varieties such as Sugandha 1 and Barkhe. Seed production and dissemination for these drought resistant cultivars has taken place through NGOs, farmers, and other innovative mechanisms of seed supply. However, the research and dissemination activities are carried out through donor funded projects of DFID and Rockefeller Foundation. No private companies are interested in the multiplication of these improved cultivars due to lack of profit margins. This research is aimed at evaluating the economic benefits of drought tolerant rice research investments and its adoption in Eastern India. We use the economic surplus model to compare the cost of research and diffusion programs through participatory plant breeding in Eastern India. Further, the causal relationship between yield levels of upland varieties obtained at the farmers' fields through trials in relation to their location and varietal characteristics were determined using simple OLS regression method. We used Unnevehrs' hedonic price model to calculate the consumer and producer surplus attributing the difference in prices between Ashoka and BG102 to better quality. Lastly, we estimated efficiency of Rockefeller funding component towards the drought tolerant rice research and seed dissemination in Eastern India. Preliminary results favored higher social returns towards both drought tolerant rice research and dissemination efforts in Eastern India.
