Abstract


Purpose. To assess the demand for sorghum seed material and sufficiency of domestic seeds.

Results. The analysis of the State register for the period of 2002–2012 showed that there was the tendency not only towards increasing quantity of sorghum crops in general but their substitution by hybrids of foreign breeding. During the period from 2002 to 2017, 72 sorghum varieties were entered on the State register in total, among them only 12 varieties were of domestic breeding, the rest 60 was presented by foreign breeding institutions. Investigation results allowed to determine that the production of base and prebase seeds of sorghum in 2010 amounted to 1,3 t, in 2016 was 43 t. During the same period the production of sugar sorghum increased from 0,2 to 12,0 t, grass sorghum – from 4,0 to 83 t. In 2017, requirements of acreage of such crops as grass sorghum and broomcorn were completely satisfied by the amount of grown seeds. At the same time, the need for seeds of sorghum and sugar sorghum can not be covered completely at the expense of domestic varieties reproduction. In 2017, general demand for sorghum seeds was 400,5 t, among which only 42,0 t was of domestic production. The rest demand for seeds will be met at the expense of import of foreign breeding seeds into the country to be grown and prepared for sowing abroad.

Conclusions. In the Register of plant varieties suitable for dissemination in Ukraine, there are 72 sorghum varieties among them only 12 varieties were of domestic breeding, that is 17%, as compared to 83% of recommended great sorghum varieties of foreign breeding. In Ukraine, the area occupied by sorghum cultivation was 22,8 thou ha in 2005, up to 2017 it increased to 89,0 thou ha, and accordingly the demand for seeds run up from 102,6 to 400,5 t. The area occupied by the sugar sorghum in 2005 amounted to only 2,6 thou ha, in 2017 – 20,0 thou ha, that accordingly determined increase of demand for seed material from 13,0 to 99,9 t. In 2017, the part of the area where domestic hybrids of sorghum are growing was 10%, hybrids of sugar sorghum – 12%, that was indicative of very poor situation with domestic varieties dissemination.
