The construction of genetic linkage map in Camellia. a A genetic linkage map containing 4255 markers is constructed based on F1 hybrids from C. japonica and C. chekiangoleosa. b The floral morphology of C. japonica (left) and C. chekiangoleosa (right). c, d The violin plot of the floral size (c) and stamen numbers (d) for the parents and F1 offspring (n = 10), respectively. The flower size and stamen number of C. chekiangoleosa are significantly larger than those of C. japonica
