To understand total flavonid content of rice landraces with different seed coat color and their correlations with germination quality. 17 rice landraces from Yunnan province were used to measure total flavonoid content in grains,brown rice and husk. The germination indexes of grains and brown rice including seed germination force(GF),germination percentage(GP),germination index(GI),vigor index(VI) were investigated. The results showed that there were significant difference in total flavonid content of grains and brown rice with purple and red seed coat,which was very significantly higher compared with that from white seed coat. However,there was no significant difference in total flavonoid content of husks. The above 4 germination indexes of grains with red seed coat were better than that of purple and white seed coat,respectively. However,it was only significant difference of seed germination force between grains with red and white seed coat. The 4 germination indexes of brown rice with red seed coat were very significantly higher than that of purple and white brown rice. The other 3 germination indexes of brown rice with purple seed coat were also significantly or very significantly higher than that of white seed coat except for GI. These results showed that total flavonoid content of colored grains and brown rice were higher that of colorless. The germination indexes of colored grains and brown rice were also higher than that of colorless. There was no significant correlations existed between total flavonoid content and 4 germination indexes in grains. However, significant positive correlation was found between the total flavonoid content of brown rice and 4 germination indexes. These results indicated that flavonoids of grains didn’t make contribution to seed germination . However flavonoids of brown rice significantly affect seed germination Characteristics.
