Abstract: Present communication encompasses detailed studies on genetic system of Artemisia tournefortiana Reichb., (F. Asteraceae) sprawling at Rumtse, Khardong and Kharu areas of Ladakh region of Jammu & Kashmir, India . Species has high sexual reproductive efficiency and exhibits a stable genetic system with diploid chromosome constitution and high pollen stainability resulting in good seed set averaging 60.61+1.55 on open pollination. Plants of the species studied by us are based on x=9 and invariabily exhibit 2n=18 as their chromosome number. Somatic analysis reveals presence of 16M and 2 SM chromosomes.
Keywords: Artemisia, Chromosome, Genetic system, Reproductive efficiency, Somatic analysis
