Technology for cultivation of pre-basic and basic parental seeds, as well as certified sunflower seeds, is similar with the intensive technology for cultivation of commercial seeds. Due to the goal of producing high quality and genetically pure seeds, relatively free of pathogens, in the case of hybrid seeds production, some requirements are mentioned, as follow: spatial isolation of the fields; cultivation in the fields with fertile soil; sunflower in crop rotation should lie on the same field not earlier than 6-7 years. In order to ensure a higher genetic quality of the seeds, the female inbred line should be pollinated only from the pollen of selected male inbred line, that’s why the fields must be isolated from pollen from other sources. The minimum distance from neighboring sources of pollen that could generate undesirable pollination should be: more than 1500 m – for the production of basic seed of hybrids and of the varieties other than hybrids; and minim 1200 m – for the production of certified seeds. Sunflower is cultivated preferentially in the rotation with autumn or spring cereals (wheat, oats, barley, corn etc.). Due to their susceptibility to many common diseases (Sclerotinia, white and grey mold etc.), it is not recommended to sow sunflower in the field where sunflower, rape, soybeans, beans, chickpeas or mustard were cultivated the last 6-7 years. Over the 20 years the sunflower hybridization areas in the seeds production companies, ranged between 5672 ha (1996) and 10543 ha (1991), ensuring a harvest from 2000 (1998) to 9382 (1992) tonnes of seeds from the first generation, which has fully ensured the sowing of fields for commercial sunflower seeds production. Since 1999, the technologies of seeds production from Research Institute for Field Crops have been partially taken over by the company Magroselect, and then (in 2010) by the Agroselect Comert SRL. Within AMG - Agroselect Comert SRL during the period 2011-2017, 84 tonnes of basic seed of parental forms were grown on a total area of 140 hectares. The quantity of basic seed allows the growth of hybrid seeds according to the plan drawn up based on buyers' demand. The production of certified seed during this period was carried out on a total area of 6800 ha, from which 5500 tonnes were harvested, cleaned, stored and commercialized. Although only 150 years have passed since the introduction of sunflower in the Republic of Moldova, we can surely observe that this branch
