Abstract
Epilobium parviflorum Schreb. is a new medicinal plant used in cases of prostate’s adenoma.
The domestication of this increasingly popular and expensive plant is justified, especially in view of the elaboration of a pharmaceutical speciality, wich needs raw material with a standardized chemical composition.
Therefore, a good knowledge of the breeding system of the plant is needed in view of seeds production and also for the genetic improvement of the species.
A determination of the rate of cross-pollination of E. parviflorum has been carried out in 3 different sites, using the very variable sensitivity of different lots of E. parviflorum to powdery mildew (Sphaerotheca epilobii) as a genetic marker.
In each site, sensitive and resistant plants have been self-fertilized.
Controlled cross-fertilization and free pollination have also been realised between the two types of plants.
The observation of the sensitivity of progenies to the pathogen revealed that the rate of cross-pollination in field conditions varies between 2.4 and 8.3 %, with significant differences between the 3 sites.
