Background : Panax ginseng the king of Oriental medicines, has enormous potential against many of the disease symptoms and ailments. Panax quinquefolius is an another important member of Panax family which has similar benefits and medicinal properties. Both the species contains ginsenosides a pharmacologically active component abundant in their roots. In an effort to establish the new ginseng cultivars with improved agronomical characters such as root shape, stress tolerant and higher ginsenoside contents, the reciprocal interspecific hybrids were generated Methods and Results : Four elite cultivars and two new lines of ginseng were chosen to produce interspecies reciprocal hybrids with P. quinquefolius, by pollen dusting on the emasculated flowers. Among the F1 populations, the reciprocal hybrids generated by using new line 0837 both as maternal and paternal parent showed better properties and hybrid vigor. They showed strong root phenotypes with many lateral and fine roots thus having 10% to 20% higher ginsenoside contents compared to the parental populations. Among the major ginsenosides, the pharmacologically active ginsenosides such as Re, Rb1, Rb2 and F1 were enriched and accounted for the 70% of the PPD ginsenosides in 0837/Pq and Pq/0837 crosses, displaying strong dominance. Conclusion : Thus, based on our result we could conclude that P. ginseng line 0837 is the superior variety compared to the already existing lines for performing the interspecific hybrids with promising outcome in their root quality and ginsenoside content.
