[Induction and identification of autotetraploid plant of Platycodon grandiflorum].
The methods and technique of inducing polyploid plants of Platycodon grandiflorum were done. Many autotetraploid plant lines were induced by colchicine in vitro successfully. The identification of main agronomic characteristics of these clonal lines was conduced in the fields. The results showed the giant type occurred in tetraploid plants comparing with that in diploid plants. It may show prospective way in developing new varieties with high yield and high content of useful compounds.
