Abstract: Demonstration of crop new varieties has played an important role in agricultural extension. This paper constructed an evaluation index system of osculation value model by survey data collected during 2015 investigation, and analyzed the production advantages of Yugu 18, local corn and local foxtail millet, so as to evaluate the demonstrative effect of new foxtail millet variety Yugu 18 in various regions. The results showed that the score of Yugu 18 osculating value in 4 regions was the lowest, but it ranked the first among crops from these 4 regions, showing obvious relative advantage. It was the most promising crop with bigger development potential. This conclusion has provided a theoretical support for the planting area expansion of coarse grain Yugu 18 under the current “sickle bay”plan.
