In this article names of hybrids of sunflower of different groups of ripeness are listed. The short characteristic of hybrids of new generation for cultivation is provided in steppes.

For the last 5 years 22 hybrids of sunflower of different groups of ripeness are created and transferred to the State sortoispytaniye.
The short characteristic of sunflower of hybrids of the new generation recommended for cultivation in the steppe.
The ANNOUNCEMENT – a simple interlinear early ripe hybrid with the vegetative period of 100-105 days. Height of plants – 150-160 see. Basket thin, slaboponikshy. Diameter – 18-22 see Maslichnost of seeds – 51-53 %. Mass of 1000 seeds – 55-70 gr. Potential productivity – 5,2 t/hectares.
SYMBOL – a simple interlinear early ripe hybrid with the vegetative period of 105-110 days. Height of plants – 160-170 see. A basket thin, slaboponikshy, diameter – 18-22 see Maslichnost of seeds – 51-52 %. Mass of 1000 seeds – 52-70 gr. Potential productivity – 5,0 t on hectare.
OLIVER 90–simple interlinear early ripe hybrid with the vegetative period of 105-110 days. It is characterized by the high content of olein acid in oil (88-90 %). The Maslichnost of seeds – 50-52 %. Mass of 1000 seeds – 57-70 gr. Height of plants – 130-160 see. A basket thin, slaboponikshy, diameter – 18-22 see. Potential productivity – 4,2 t/hectares.
ODOR-a simple interlinear early ripe hybrid, with the vegetative period of 107-112 days. The Maslichnost of seeds – 50-52 %, mass of 1000 seeds – 50-70 gr. Height of plants – 165-180 see. A basket thin, slaboponikshy, diameter – 18-22 see. Potential productivity – 5,0 t/hectares.
ZGODA-a simple interlinear early hybrid, with the vegetative period – 112-118 days. Height of plants – 150-180 see. A basket thin, a little hung, diameter 18-24 see Maslichnost of seeds – 49-52 %. Mass of 1000 seeds – 55-62 gr. Potential productivity of 4,6 t/hectares
All described hybrids of sunflower differ high productivity, endurance to adverse conditions of cultivation, stability to the most harmful diseases and the high content of oil.
In the Crimea not bad proved also a sunflower grade PROMETHEUS who in some farms gives productivity of seeds to 25 c/hectares.
In summary it is necessary to note that the main source of providing plants of sunflower moisture, are its stocks which have been saved up for the autumn and winter period. To count on receiving an acceptable crop of sunflower it is possible only in case of a soil promachivaniye for this period on depth not less than 1 meter and the content of available moisture within 170-180 mm. Such stocks of moisture this year in many regions of the Crimea isn’t available, and loss of a precipitation during vegetation at low stocks of moisture before crops, won’t provide necessary need of plants of sunflower for it.
According to mean annual data of the Klepininsky meteorological station from April till August only 62 mm of the precipitation which about a half doesn’t get to a korneobitayemy layer of earth drop out, and evaporates in the atmosphere it means that the need of sunflower for moisture for receiving a crop within 1,5-2,0 t/hectares won’t be provided. Therefore in the conditions of 2008 it is not necessary to go on considerable expansion of the areas of sunflower in not irrigated conditions, and at crops to use the early ripest hybrids and grades.
