Agrobiological parameters of various varieties and hybrids of sweet sorghum

Purpose. To reveal the features of agrobiological parameters formation sweet sorghum various varieties and hybrids in conditions Right-Bank Forest-Steppe Ukraine.
 Methods. During 2018–2020 twenty-one ecological geographical origins (Ukraine, Russia, USA, France, Germany, Hungary, Brazil) were studied field. Parameters like plant height indices their individual productivity (grain weight per panicle, 1000 grain weight, etc.), yield dry biomass grain, content sugar juice protein as well estimated a crop. The counts carried out phase physiological ripeness culture.
 Results. In group Ukrainian hybrids, plants from 272 to 306 cm high, foreign – 274 412 cm. Varieties ‘Red Amber’, ‘Sioux’, ‘Affas CJ 899’, ‘Freed’ ‘Early Orange’ are high value for breeding practice, tallest 388 panicle length cultivars ranged 16.0 17.3 cm, 11.0 19.4 Grain one varied 32.8 41.6 g 29.2 43.5 g, respectively. wide range, depending on varietal characteristics, indicator number grains also 1338 1708 pcs. mass 28.0 31.0 breeding, ones 19.3 g. vegetative was at level 8.24–9.11 t/ha. highest rates shown hybrid ‘Mamont’ ‘Huliver’ variety 9.05 9.11 t/ha, For this 7.00 12.17 Significantly higher comparison with standard (‘Sylosne 42’) produced by ‘Vorai Sumac’, ‘Sorgo Cucre’, ‘Freed’, ‘Mohavk’, 9.03–12.17 15.2 17.2%. 0.82–0.89 0.72 1.18 all it 0.94–1.18 t/ha.
 Conclusions. varies greatly origin hybrid. Forest-Steppe, order obtain yield, is advisable grow ‘Sylosne 42’, ‘Favoryt’, ‘Troistyi’, ‘Dovista’, ‘Ananas’, ‘Medovyi’, hybrids. ‘Vaconia Orange’, Cucre’ ‘Ald Sorghum’, provide yields masses. Hybrids 899’ produce large (11.08–12.17 t/ha), (8.00–8.15 t/ha) (9.8–11.3%).
