Khumal-4 rice is popular and widely grown in mid hills region of Nepal which was developed by crossing a high yielding dwarf foreign sourced germplasm IR-28 with a local Nepali variety <em>Pokharilo Masino</em>. Economic benefits of Khumal-4 rice adoption and impact was analysed using economic surplus model, where additional productivity and profitability gained from developing Khumal-4 was estimated in monetary value in comparison with existing farmers’ variety <em>Pokharilo masino</em>. The finding showed that Khumal-4 covered 9% of rice area in the mid-hills and 7% in the mountains during year 2010-12 years covering about 40 thousand hectares of rice area. Data show that there is a clear yield gain of 1.25 mt per hectare with cost in rice yield equivalent when farmers switch from traditional <em>Pokhareli Masino </em>to improved Khumal-4 variety. Estimation of additional revenue per hectare with total adoption area of Khumal-4 in prevailing market price in Nepal was NRs 1.07 billion (US $ 11 million) per annum. This is reasonable economic benefits obtained annually from flow of foreign sourced genes (IR-28) for the development of an improved Khumal-4 rice variety in Nepal. This finding indicates that access to foreign germplasm is important for ensuring national food security and gaining higher economic benefits in the country.</p><p><strong>Agronomy Journal of Nepal (Agron JN)</strong> vol. 4, 2016</p> ER -
