Variation in yield and yield components in cultivated accessions of Satureja macrantha in Yazd

Background & Aim: The genus Satureja belonging to the family of lamiaceae and consists of over 235 different species throughout the world. Fourteen species grow naturally in IRAN of which eleven species are endemic. Different species of Satureja are used in food, Healthy, cosmetic and medical industry. This reseach has been carried due to selection and introduction of suitable germplasm in Satureja macrantha accessions. Experimental: This reseach has been carried in medicinal plants research station inYazd province with the coordinates of longitude and latitude 55 31 49 northly, 27 15 54 east to a heigh of 1209 meters above Sea level in the region Gerdefaramarz city of Yazd shahedial. In order to in the first year seeds 3 accession of Satureja macrantha obtained from the research institute of forsts and Rangelands, were planted in jifypot and in the green house. Then seedling in case of randomized complete block with three replication were planted on the main floor. Rate of plant establishment, canopy diameter, plant height, yield, essential oil yield per hectare, percentage of essential oil, were meseared and recorded. Results & Discussion:The results showed, analysis of variance rate of plant establishment at the level of one percent was significant and plant heigh, canopy diameter, yield, essential oil yield per hectare, percentage of essential oil, dry weight of shoot and leaf, were not significant. Regarding to yield, percentage of essential oil, essential oil yield per hectare and amount plant stablishment accessions SM1 with mean of yield(2410 kg/ha), percentage of essential oil(1.03%), oil yield(15.8kg/ha) and amount plant stablishment(42.7%) with origin East Azarbayejan province was selected superior accessions. Recommended applications / industries: Because of that in Satureja macrantha is essential oil and high yield. for planting in the same climate zones is recommended.
