ABSTRACT
<p><b>OBJECTIVE</b>To characterize the different varieties of Pseudostellaria heterophylla during cultivation.</p><p><b>METHOD</b>Using systematic selection in the main productive areas, the techniques of random design, all varieties were observed for 3 years.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>The strain types of P. heterophylla was denominated for the first time. The characteristics and productivity index system of P. heterophylla varieties were determined.</p>
