In the early 2000s, it has been proposed for implementation a number of new plants for Moldova. One of them was Origanum vulgare ssp, hirtum (Link) Ietswaart (1), which subsequently appeared promising and currently occupies more than 300 ha. Origanum vulgare var. vulgare L. is a perennial herbaceous plant, which has various uses: in medicine, food industry (spice), as aromatic and as melliferous plant. It is particularly appreciated for the production of essential oil, which due to phenolic compounds (carvacrol and thymol) has antimicrobial, antifungal, antioxidant action [2, 3, 4]; it has natural Eurasian habitat, with many biotypes, genotypes and forms. Origanum vulgare ssp. vulgare is spread in Moldova, while Origanum vulgare ssp. hirtum in the wild flora of the country is not found. These subspecies have identical uses but differ greatly among themselves both morphologically and by the content and composition of volatile oil (2). At Origanum vulgare ssp. vulgare technical conditions for pharmaceutical raw material are developed (5). At Origanum vulgare ssp. hirtum these conditions are lacking. At the Institute of Genetics, Physiology and Plant Protection were made researches on which it could be possible to elaborate technical conditions for the reception of raw materials. The researches were performed on Origanum  vulgare ssp. vulgare, local population, and on ssp. hirtum – with generative descendants of fertile line no. 54 of German origin. The researches were conducted on plantations in the third year of vegetation. In flowering phase, plants were harvested and investigated morphologically and biochemically. In whole plants and in parts of segments 0-20 cm, 2030 cm, 30-40 cm and below 40 cm from the top, it was determined the weight ratio of the flowers, leaves, stems and the volatile oil content in them. The mass was determined by weighing and the content of essential oil - by hydrodistillation. Ssp. vulgare plants in culture conditions, by flowering, are tall (76 cm), but only 20-25 cm from apical side is leafy and can be used as pharmaceutical raw material. Hirtum subspecies plants are smaller and reach 69-70 cm, have leafy stalks almost on their entire length, with bloom much more diffuse than at ssp. vulgaris. The mass of 25 shots at flowering is 179 g at ssp. hirtum and 112 g at ssp. vulgare. Both subspecies are volatile oil rich in flowers (inflorescence) followed by leaves. In stems, volatile oil is lower or is completely missing. But the volatile oil accumulation in the whole plant at flowering stage ssp. hirtum is 5-6 times higher compared to ssp. vulgaris and properly accounted 2.570% and 0.467% (absolutely dry mass).  At ssp. vulgaris, 94% of the inflorescence is located in segment 0-20 cm from the top, while at ssp. Hirtum, inflorescences persist as well in segments 20-30 cm and 30-40 cm. Volatile oil content (absolutely dry mass) on segments 0-20 cm, 20-30 cm, 30-40 cm and > 40 cm properly constituted 1.020; 0.251; 0.108 and 0.053% at ssp. vulgare and 2.880; 1.145; 0.926 and 0.377% at ssp. hirtum. Given that the volatile oil content is higher on lower segments at ssp. plant hirtum, whole leafy plant has a useful production. This fact was confirmed in practice and production conditions. In 2015, agricultural specialized  enterprises in Căuşeni district, ssp. hirtum cultivated on area of 160 ha, the whole plants being harvested in full flowering phase with cutting at 8-10 cm above the ground have achieved high production of over 70.0 kg /ha of volatile oil, getting 12.8 kg of volatile oil per each tonne of fresh herbs. So, at the ssp. Hirtum, aromatic raw material will consist not only of the plant segments with length of 20 cm (applies to ssp. vulgare) but of all leafy plant, harvested at full flowering by cutting at 8-10 cm above the ground.
