بررسی تنوع ‏ژنتیکی صفات مورفولوژیکی، فنولوژیکی و عملکرد اسانس تعدادی از جمعیت‏های گونه بابونه کبیر (parthenium Tanacetum)

In order to evaluation of identification of 5 populations of the Chamomile parthenium Tanacetum species, an experiment was conducted in a Randomized Completely Blocks Design (RCBD) with three replicates. 12 quantitative and qualitative traits such as: length and width of vegetative crown, plant height, flower number per plant, fresh and dry weight, time of flowering, time of harvest, essential oil percentage, essential oil yield, growth degree days of flowering and harvest were measured. Analysis variance showed that there was significant difference between population for all traits population for parthenium Tanacetum species (p ≤0.01) except for essential oil yield which was significance at p ≤0.01 . Simple correlation analysis showed that there was significant positive correlation between flower number per plant with length and width of vegetative crown, plant height traits. This study showed that gorgan3 population of parthenium Tanacetum species, considered as superior population. Population of Golestan3 had lower value of growth degree days in flowering and harvesting time and it was considered as earlier population compare with other populations.
