Relevance. Vegetable seed production is a key step in using of new varieties/hybrids in agriculture. The main problem of vegetable seed production is the negative effect of environment to the seed productivity of plants and seeds quality. Usually, vegetable seeds produce in greenhouses in Russia, but special greenhouses are necessary for the obtaining of qualitative seeds. Possibilities different types of greenhouses for seed production of new special tomato varieties for multi circle hydroponics have been studied at this paper.Materials and methods. Materials of study: plants, fruits and seeds of two new tomato varieties Natasha and Timosha. Influence type of plants cultivation on the yield, plant productivity, the middle mass of the fruit and seeds quality have been studied at the two factorial experiment, which has been carried out with help of random repetitions method with 4 repeats. Seed quality has been evaluated by GOST 32 592-2013. Experimental data have been calculated with dispersion analysis by B.A. Dospekhov (1985).Results. It has been established, that the environment of “Rishel” greenhouse (France firm “Rishel”) with polycarbonate cover is optimal for the seed production of new tomato varieties Natasha and Timosha for multi circle hydroponics. The productivity and the yield of seed’s plants were significantly higher in “Rishel” greenhouse, than in the usual greenhouse. The middle mass of one fruit at the plant was significantly higher too. The quality of seeds was in accordance to GOST 32 592-2013 for qualitative tomato seeds (2014).
