The special band of TN1 population maybe link with avirulence, it was quality character confirmed by genetics experiment and tested by X2-test, followed 3:1 segregationratio.
Segregation index of calculation is consistent with experimental data under different volumetric ratio and rotating speed.
在不同的转速和不同的体积比下，计算得到了与试验值较符合的离集指数。
3
The texture ratio between segregated area and non-segregated area is used as the evaluation index of segregation, the evaluation criteria of different level segregation is obtained.
