Microsatellite markers are used to analyze the genetic background of KM outbred mice from Shanxi. The two populations were bred by mating in an outbred manner for nine generations and nineteen generations (named A9 and A19 respectively). Seven SSR markers located on seven different chromosomes were utilized in this research, D3Mit22 was selected for detailed analysis.

The results showed that 13S5 and 13S8 tended to grow faster but sporulate less during subculturing. Sporulation was not significantly different in the first 6 generations, but after subculturing over 6 to 7 generations the sporulation declined significantly, by 81.7% and 69.0% respectively, as compared to that of the first generation.

结果表明，野生型出发菌株Bb13的单孢分离株13S5和13S8在继代培养过程中均发生生长速率加快和产孢量下降现象。13S5在前5代，13S8在前6代产孢量有所下降但不显著，至第10代时产孢量比第1代分别下降了81.7%和69.0%。

Meanwhile, our successive observations for 3 generations on several lines of untransformed regenerants indicated that, their fertility under long-day showed a trend to return to normal level of original materials with the advancement of generations. But the transgenic lines still kept more stable and relative higher level over the control under long-day.
