In order to understand the optimal storage time of millet seeds under natural storage conditions,65 varieties of foxtail millet seeds from regional trial of late-maturing millet group in China from 2011 to 2015 were used for germinating test in this study. The changing trend of germination rates during the storage periods was analyzed,and the annual differences were analyzed by one-way ANOVA and multiple comparisons. Meanwhile the changes of germination rate of different varieties in the same annual interval were analyzed. The results showed that 4 years of seed storage was a key inflection point,and the germination rates were significantly declined. The variation of coefficient was obvious among different varieties. In 2013,the germination rate of Chao 201058 was only 10. 5%,while the germination rate of Changnong 35 was as high as 92. 5%. Among the varieties participating in the 2 year regional experiment from 2012 to 2013,the germination rates of 7 varieties differed greatly from 10. 0% to 67. 5%.When the seeds were stored for 5 years and 6 years,the germination rate declined to below 21. 0% and15. 5% respectively.
