Variance type of capsule morphological characters in Platycodon grandiflorum population.

[Objective] The aim was to study variance type of capsule morphological characters in Platycodon grandiflorum population,and provide some theoretical basis for seeking to genetic markers which can differentiate different P.grandiflorum and breeding new varieties.[Method] According to shape morphological characters of capsule from the same population of perennial purple P.gandiflorum,seven types of distinct diversity capsule were selected,variance analysis and multiple comparison on the length,diameter,length/diameter of the different types of capsule were carried out.[Result] There is unicolor and bicolor,even trichrome,among main color was brown and purple.Capsule shape was main cone,furthermore,containing long roller type,spheroidicity and sphericity.[Conclusion] P.gandiflorum capsule was divided into long form,short form and middle type from length/diameter size in perennial culture P.gandiflorum population.
