Abstract
Artemisia scoparia Waldst & Kit. (F: Asteraceae), a potent source of scoparone forms populations in foot hills of North-West Himalayas at different climes that include Jammu (332 masl), Rajouri (915 masl) and Kud (1705 masl) regions of J&K state, India. It is a luxuriantly growing plant in the areas of study. The plant exhibits a stable genetic system with diploid chromosome constitution (2n=16) and high pollen viability resulting in high sexual reproductive efficiency. An interesting feature in the species of study is the presence of functional monoecy. The species is predominantly an outcrosser exploiting anemophily. Seed set on open pollination is adequate in dense populations ranging from 52.5% to 60.4%. Present communication encompasses detailed studies on the genetic system of this wormwood species; with focus on the role of functional males in the capitula in percentage seed set in this species
