This research was carried out with the aim of introducing the most suitable accessions in T. kotschyanus and T. lancifolius species of the thyme genus for the development of cultivation in low salinity water and soil conditions at the Pardisan Salinity Research Station of Qom. The seeds of 7 accessions along with the control (T. vulgaris) were planted in the greenhouse and in GF pots in January 2016, and in April of the following year, potted seedlings were planted in the main field in complete randomized block design in three replications. In this experiment, aerial organ function, percentage and yield of essential oil in two years and the percentage of essential oil compounds in the second year were measured and determined. Essential oil extraction was done by water distillation method and essential oil analysis was done by gas chromatography method. The results of composite variance analysis of traits showed that the effect of population, year and the interaction of year in population were significant in all traits at the probability level of one or five percent. The results of the comparison of the average traits in the investigated species showed that the average T. lancifolius species was superior to the average of the other two species in terms of essential oil yield in the first, second and second years. Among the four populations of T. kotschyanus, populations 5 and 70 were superior to other populations of this species in terms of percentage and yield of essential oil. Population 48 of T. lancifolius species was superior to other populations in terms of many traits alone or with population 45 of the same species. In total, 48 and 45 populations of T. lancifolius species from Khorramabad and Faridunshahr regions, respectively, and 5 and 70 populations of T. kotschyanus species from Qazvin and Urmia regions, respectively, can be used for the development of cultivation in areas with brackish water and soil. and also be introduced as candidates for the introduction of promising cultivars of these species in these conditions. Carvacrol chemotypes were identified in Qazvin 1 and 2 accessions, thymol in Naqdeh accession and geraniol in Qazvin 1 accession.

EXTENDED ABSTRACT
In recent years, the quantitative and qualitative reduction of water resources has become a national problem, and agriculture, as the largest consumer of water, is facing the greatest damage and threat. One of the major and effective ways to get out of this crisis is to modify the cultivation pattern and optimal production management. Medicinal plants have a special place in the cultivation pattern modification program due to their impact on society's health, great added value and the potential to create employment.
This research was carried out with the aim of introducing the most suitable accessions in T. kotschyanus and T. lancifolius species of the thyme genus for the development of cultivation in saline soil and water conditions, at Pardisan Qom Salinity Research Station.
The seeds of 7 accessions along with the control (T. vulgaris species) were planted in the greenhouse and in GF pots in January 2016, and in April of the following year, potted seedlings were planted in the main field in the form of a randomized complete block design in three replications. In this experiment, aerial organ function, percentage and yield of essential oil in two years and the percentage of essential oil compounds in the second year were measured and determined. Essential oil extraction was done by water distillation method and essential oil analysis was done by gas chromatography method.
The results of composite variance analysis of the traits showed that the effect of population, year and the interaction of year in the population were significant in all traits at the probability level of one or five percent. The results of comparing the average traits in the investigated species showed that the average of T. lancifolius species was superior to the average of the other two species in terms of essential oil yield in the first, second and average years. Among the four populations of T. kotschyanus, populations 5 and 70 were superior to other populations of this species in terms of percentage and yield of essential oil. Population 48 of T. lancifolius species was superior to other populations in terms of many traits alone or with population 45 of the same species.
In total, 48 and 45 populations of T. lancifolius species from Khorramabad and Faridunshahr regions respectively and 5 and 70 populations of T. kotschyanus species from Qazvin and Urmia regions respectively, for the development of cultivation in areas with brackish water and soil and They were also introduced as candidates for the introduction of promising cultivars of these species under these conditions. Carvacrol chemotypes were identified in Qazvin 1 and 2 accessions, thymol in Naqdeh accession and geraniol in Qazvin 1 accession.
