Sorghum is cultivated in many countries of the world on around 50 ml hectares. The main producers of sorghum are India, Nigeria, Sudan and the USA. Sorghum comes from equatorial Africa. India and China are the secondary places of origin and formation. The USA achieved great success in breeding, seedgrowing and agro technologies of grain sorghum. In the country sorghum occupies 14.4% of the world amount of sowing areas; the gross yield is 40%. Sorghum breeding on Don was started by E.S. Yakushevsky in 1938. In 1963 after a long break the work was restarted at the Zernograd Breeding Station headed by Ya.I. Issakov. At present the amount of sowing areas for sorghum is constantly increasing in RF (220.3 thousand ha in 2015). It occurs due to aridity of climate and more frequent use of the crop as insurance. Besides, the development of white kernel varieties gave an opportunity to use sorghum for starch and spirit. There are 221 varieties and hybrids of sorghum registered in the State List. The main directions of breeding work with grain sorghum are early maturity, suitability for mechanical harvesting, productivity and grain quality. The ARRIGC developed the white kernel early maturing varieties ‘Velikan’, ‘Zernogradskoe 88’, ‘Ataman’ without necessity to be dried after harvesting, with productivity of 8 t/ha. The main directions of breeding work with sweet sorghum are early maturity, high intensity of initial growth, low height, resistance to lodging, high productivity and quality of green chop. The ARRIGC developed the varieties for fodder use (‘Listvenit’), for spirit and treacle (‘Debyut’ and ‘Zernogradsky Yantar’). Sorghum due to origin and varietal diversity even in dry and hot parts of the world allow obtaining stable, high yields of grain and green chop. This makes sorghum the leading grain-forage and food crop
