Objective:
To characterize the different varieties of Pseudostellaria heterophylla during cultivation.
Method:
Using systematic selection in the main productive areas, the techniques of random design, all varieties were observed for 3 years.
Result:
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.
Conclusion:
The strain types of P. heterophylla was denominated for the first time. The characteristics and productivity index system of P. heterophylla varieties were determined.
