| 摘 要： | 通过实地抽样调查及田间试验得到品种比例、小种比例和品种×小种适合度等参数,将其输入某种运算程序进行在一定程度上符合小种消长实际情况且合乎逻辑的运算得小种比例预测值,与实测值相比较,条中29号被预测为上升最快的小种,这符合近年来29号发展为优势小种的实际情况,但各小种预测值与实测值相差甚大,文中对其原因进行了分析。

| Abstract: | The variety propprtion in wheat population and the frequency of race in pathogen was monitored.The fitness of variety race was measured in field.Based on these parameters,the race frequency was predicted by simulation.The results showed that the frequency of race NO.29 increased repidly,this tally with the practi- cal change of race NO.29.But,there is much difference between the value predicted by simulation and he value measured by investigating. The reason was analysed in the report. |
