Background and ObjectivesSatureja rechingeri, belonging to the Lamiaceae family, has been recently used in the pharmaceutical industry due to its high level of carvacrol in the essential oil. In order to select suitable clones for commercial cultivation in Dezful climatic conditions, in this study morphological and biological production traits of 58 clones of Satureja rechingeri were evaluated.
Materials and Methods After initial screening of plant populations, 58 genotypes were selected based on their adaptation into field conditions. To evaluate the morphological and biological production traits of these clones in Dezful climatic conditions, an experiment was conducted based on randomized complete block design with three replications. Morphological and biological production traits of 58 clones were evaluated in the second year of cultivation at the flowering stage.
Results Analysis of variance showed significant differences for all studied traits (pDiscussion Superior S. rechingeri clones could be used for commercial cultivation in Dezful climate conditions. The most important biological production traits, yield of leaf and flower fraction, essential oil content and yield showed significant variation between clones. These variations could be used to breed high-quality and desirable cultivars for use in food and pharmaceutical industries.

Satureja rechingeri, an endemic species from Iran, is distributed in narrow habitats in Ilam and Khuzestan provinces. This study was conducted in 2013 and some morphological characteristics, oil content, rosmarinic acid content and ecological features of different populations of S. rechingeri were studied. Identified habitats of S. rechingeri are located in sub-tropical areas of Ilam and khuzistan provinces, within 32-33◦ longitude and 46-49◦ latitude and the plant mainly grows on calcareous rocks in the northern and southern slopes. The highest coefficient of variation among the traits of S. rechingeri was obtained for leaf surface area (43.01%) and the lowest (9.25%) was obtained for the diameter of the calyx. The coefficient of variation for essential oil yield was 33.71%. The lowest (2.1%) and the highest (3.51%) average essential oil yields were observed in Kaver and Lives populations, respectively. Minimum (0.93%) and maximum (6.2%) essential oil yields were observed among the individuals of the Lives and Kaver populations, respectively. Highest (54.49%) coefficient of variation for rosmarinic acid content was observed in Bone Adab population. Amount of rosmarinic acid of methanolic extract of under study populations showed high variability and varied from 0.54 to 7.29% among individuals, while the average rosmarinic acid in populations varied from 1.62 percent (Kaver population) to 4.14 percent (Zarrin Abad population). Diversity of S. richingeri within populations was higher than among them showing limited segregating of populations.

Satureja rechingeri, belonging to the family Lamiaceae, has been recently used in the pharmaceutical industry due to its high level of carvacrol in the essential oil. The domestication and breeding of suitable S. rechingeri variety has been started since few years ago in Iran. The initial screening of natural populations, grown in the same environment, was performed and 58 talent clones were selected. In the present study, half-sib (HS) progenies of the 58 parent clones were obtained by polycross and were evaluated in a randomized complete block design (RCBD) with six replications. Different production biological traits as plant height, main branches number, lateral branches number, leaf width and length, fresh and dry weight, dry weight of leaves and flowers and essential oil content and yield were evaluated at full flowering stage. Narrow sense heritability values based on measurement at the individual plant level (H1) and based on plot mean (H2), additive variance and general combining ability were calculated for each trait. Highest narrow sense heritability was observed for plant diameter, plant height and main branches number while lowest value was obtained for the number of lateral branches. Additive variance was significant for main branch number, fresh weight, and dry weight, weight of leaves and flowers and plant height. By selection of 20 percent of the half-sib families, based on general combining ability for essential oil yield, families of F27, Z12, Z37, F14, E59, E37, Z26, Z28, K56 and G27 clones can be selected as parents of a synthetic variety.

The prevalence of diabetes in word is rapidly rising.Stress oxidative is risk factors in diabetes. . If untreated, it is complications ,such as atherosclerosis , ophthalmic complication ,retinopathy and cardiovascular complications, nephropathy, disability and death.Satureja rechingeri essence has antioxidant effects.The aim of this study was effect Satureja rechingeri essence on treating diabetes in diabetic male wistar rats. The study was carried out on 30 male rats. Male rats were divided into three groups randomly,group one as control, group two diabetic untreated, group three diabetic treated with Saturejarechingeri essence by injection 100 mg/kg ,i.p .Diabetes was induced in the second and third groups by injection 60 mg/kg ,i.p of streptozotocin .After 3 weeks ,the serum levels of glucose،triglyceride (TG), cholesterol (C), LDL ,VLDL ,HDL of all groups were analyzed. The serum levels of glucose, triglyceride (TG), cholesterol(C) low density lipoprotein (LDL),very low density lipoprotein (VLDL) decreased in treated groups significantly.The levels of high density lipoprotein (HDL) increased in treated groups significantly. This study showed that Satureja rechingeri essence effect on treating diabetes in diabetic rats.
