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%;The observations based on cross-compatibility led to suggestions that those could be female parents, such as C.polyodonta,C.longicaudata,C.villosa展开更多
