title: [Studies on strain characteristics of Pseudostellaria heterophylla varieties].
abstract: OBJECTIVE
  To characterize the different varieties of Pseudostellaria heterophylla during cultivation.
  
  
  METHODS
  Using systematic selection in the main productive areas, the techniques of random design, all varieties were observed for 3 years.
  
  
  RESULTS
  The biological and 425 productive characteristics of P. heterophylla var. macrophylla, P. heterophylla var. Foliolum, and P. heterophylla var. anvense were significantly different (P < 0.01). There were also differences in ecological adaptability, plant characteristics, pollen granule, chromosomes, and isoenzyme of the three cultivars.
  
  
  CONCLUSIONS
  The strain types of P. heterophylla was denominated for the first time. The characteristics and productivity index system of P. heterophylla varieties were determined.
