| Abstract: |
| In order to advance tea resources and breeding efficiency in Guangxi， we tested pollen vitality and
researched interspecific artificial hybridization pollination of 8 good tea varieties（national level）. The results showed
that the vitality ranged from 31.8% to 74.24%， the Guilv 1 st had the highest with 74.24%， the Guixiang 22 st and Yaoshan
xiulv had 69.15% and 68.15% respectively， the Guihong 4 st had the lowest. The pollen vitality showed significant
differences among different varieties. The maturing rate of 8 hybridized combination was from 5.0% to 28.5%， averaged
16.0%. The maturing rates of hybridized combination using Guilv 1 st and Guixiang 22 st as male perent were higher than
that of using Fuyun 6 st and Fuding white tea as male parent. The crossbreeding compatibility of Fuding white tea hybridized
with Guilv 1 st and Guixiang 22 st was higher than that of Fuyun 6 st . According to the fruit traits， the Guilv 1 st × Funyun 6 st ，
Guilv 1 st × Fuding white tea， and Funyun 6 st ×Guilv 1 st showed excellent traits， they exceeded their parents. |
