A Preliminary Study on the Cross-compatibility among Sect.Camellia Species and C.japonica Cultivars in the Genus Camellia

By crossing experiments of some camellia species and C.japonica cultivars from 2002 to 2003, the results showed that cross-compatibility among some camellia species crossing C.japonica cultivars were better than those among some camellia species crossing species. While crossing among camellia species, the average fruit set percentage of 19 cross-combinations were 18.18% in 2002 and 21.35% in 2003,the range of fruit set percentage were from 4.00% to 64.00%.
