Agrobiological characteristics of grapevine va-riety Nizina is given. The variety was breeded by joint effords of breeder- experimenter Kraynov V.N. and ARRIV&W – Branch of Federal State Budget Scientific Institution «FRARC» as a result of interbreeding of varie-ties Talisman and Kishmish luchistyy.

The variety is of early maturation of table use. The duration of the production period for 5 studied years was 115 days with the amount of active temperatures to full maturity of berries 2673°С. The variety is characterized by high winter hardiness, the percentage of breaking buds varies from 49 to 100 %. With a total amount of minus temperature 519 0C and the absolute minimum temperature of minus 24,6 оC, bud break was 58,5 %. 90-100% of shoots were fruitbearing, fertility ratio 0.6. On a sin-gle-plane trellis, with a planting scheme of 3 m × 1.5 m, the yield from a bush was 5,5 kg or more.
