%X Aiming at the economic aspect of preserving crop germplasm resources,this paper first develops a quadratic zero-one integer programming model with the objective of maximizing crop breed diversity subject to some economic constraints. To solve the program efficiently,the paper converts the model into an equivalent one.Finally,it extends the range of the model.
