| Abstract: | A new intergeneric hybrid between Sinocalycanthus chinensis W.C.Cheng et S.Y.Chang and Calycanthus floridus was obtained firstly in China in 2001,and this hybrid plant blossomed in May,2006.The hybrid progeny presents much of the excellence of its parents,showing a high value in the horticulture.Its flowers exhibit intermediate traits with the color of mauve to pink,for white in its female parent and maroon to mauve in its male parent,and its floristic form and structure are similar to that of Sinocalycanthus chinensis,its female parent as the flowers of hybrid plant perform a large,charming,showy look.Besides,the leaves in the hybrid also exhibit the intermediate traits with the similar shape and color to Sinocalycanthus chinensis,and their size more similar to Calycanthus floridus.Moreover,the heterosis in the growth of hybrid plant is marked with the good adaptability to high temperature and intense sunrays,which inherits from Calycanthus floridus. |
