The results are displayed vividly in virtual scene which is established with program language of Visual C++ and OpenGL. At present flow field simulation manner mostly has time delay, deficient controllability, so this paper brings forward the methods of drawing flow velocity vector graphics with OpenGL in the 3D virtual scene to simulate and analyze flow field. At the same time cross section and flood analysis are completed. Accordingly, it assists flood flow field visualization and provides the more effective analysis method for the flood mathematics model research and application.

The RAPD was used to study the genetic diversity of 19 KinXin series potato cultivars. The result showed that 52 RAPD bands were amplified using 7 primer, among them 43 bands were polymorphic, and 4~9 bands were amplified in each lane. The RAPD analysis indicated that the genetic distance of 19 potato cultivars was between 0.17~0.72, average value was 0.39. When all of the polymorphic bands were analysed by cluster analysis, 19 potato cultivars were classified into 3 groups. The analysis showed that there existed close sibship among the majority of potato cultivars, and the genetic distance between the minority cultivars and the others is longer, which indicate that the genetic basis of KeXin series potato cultivars is wide.
